ICA ICA listener connection timeout Computer HKLM\SOFTWARE\Policies\Citrix\ICAPolicies\StackListenTimeout   Maximum wait time for a connection using the ICA protocol to be completed. By default, the maximum wait time is 120000 milliseconds, or two minutes. XenApp 6.0 or later (VM Hosted Apps) and XenDesktop 5.0 or later X X
ICA ICA listener port number Computer HKLM\SOFTWARE\Policies\Citrix\ICAPolicies\IcaListenerPortNumber   The TCP/IP port number used by the ICA protocol on the server.
The default port number is 1494. The port number must be in the range of 0–65535 and must not conflict with other well-known port numbers.
If you change the port number, restart the server for the new value to take effect. If you change the port number on the server, you must also change it on every plug-in that connects to the server.
XenApp 6.0 or later (VM Hosted Apps) and XenDesktop 5.0 or later X X
ICA\Auto Client Reconnect Auto Client Reconnect Computer HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix\ICAPolicies\AllowAutoClientReconnect 1=Allowed
0=Prohibited
Allows or prevents automatic reconnection by the same client after a connection has been interrupted.
Allowing automatic reconnection allows users to resume working where they were interrupted when a connection was broken. Automatic reconnection detects broken connections and then reconnects the users to their sessions.
However, automatic reconnection can result in a new session being launched (instead of reconnecting to an existing session) if a plug-in’s cookie, containing the key to the session ID and credentials, is not used. The cookie is not used if it has expired, for example, because of a delay in reconnection, or if credentials must be reentered. Auto Client Reconnect is not triggered if users intentionally disconnect.

XenApp 6.0 or later and XenDesktop 5.0 or later X X
ICA\Auto Client Reconnect Auto client reconnect logging Computer HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix\ICAPolicies\ACRLogEvents 1=Log auto-reconnect events
0=Do Not Log auto-reconnect events
Records or prevents recording auto client reconnections in the event log. By default, logging is disabled.
When logging is enabled, the server’s System log captures information about successful and failed automatic reconnection events. The server farm does not provide a combined log of reconnection events for all servers.

XenApp 6.0 or later and XenDesktop 5.0 or later X X
ICA\Auto Client Reconnect Auto client reconnect authentication Computer HKLM\SOFTWARE\Policies\Citrix\ICAPolicies\ACRRequireAuth 0=Do not require authentication
1=Require authentication
Requires authentication for automatic client reconnections.
When a user initially logs on to a server farm, XenApp encrypts and stores the user credentials in memory and creates a cookie containing the encryption key which is sent to the plug-in. When this setting is added, cookies are not used. Instead, XenApp displays a dialog box to users requesting credentials when the plug-in attempts to reconnect automatically.

XenDesktop 5.0 or later X  
ICA\End User Monitoring ICA round trip calculation Computer HKLM\SOFTWARE\Policies\Citrix\EndUserMonitoring\IcaRoundTripCheckEnabled 1=Enabled
0=Disabled
Enables or disables the calculation of ICA round trip measurements. By default, ICA round trip calculations are allowed.
The ICA round trip is the time interval, measured at the client device, between the first action a user takes (such as typing the letter “A”) and the result of that action (such as the graphical display of the letter “A”).
By default, each ICA roundtrip measurement initiation is delayed until some traffic occurs that indicates user interaction. This delay can be indefinite in length and is designed to prevent the ICA roundtrip measurement being the sole reason for ICA traffic. To perform round trip calculations regardless of user activity level, configure the “ICA round trip calculations for idle connections” setting.
To set the interval at which calculations occur, configure the “ICA round trip calculation interval” setting.
XenApp 6.0 or later and XenDesktop 5.0 or later X X
ICA\End User Monitoring ICA round trip calculation interval (Seconds) Computer HKLM\SOFTWARE\Policies\Citrix\EndUserMonitoring\IcaRoundTripCheckPeriod   The frequency, in seconds, at which ICA round trip calculations are performed. By default, ICA round trip is calculated every 15 seconds. XenApp 6.0 or later and XenDesktop 5.0 or later X X
ICA\End User Monitoring ICA round trip calculations for idle connections Computer HKLM\SOFTWARE\Policies\Citrix\EndUserMonitoring\IcaRoundTripCheckWhenIdle 1=Enabled
0=Disabled
Determines whether ICA round trip calculations are performed for idle connections. By default, calculations are not performed for idle connections.
By default, each ICA roundtrip measurement initiation is delayed until some traffic occurs that indicates user interaction. This delay can be indefinite in length and is designed to prevent the ICA roundtrip measurement being the sole reason for ICA traffic.
XenApp 6.0 or later and XenDesktop 5.0 or later X X
ICA\Graphics Display memory limit Computer HKLM\SOFTWARE\Policies\Citrix\GraphicsPolicies\MaxDisplayMemory   Specifies the maximum video buffer size in kilobytes for the session. By default, the display memory limit is 32768 kilobytes.
Specify an amount in kilobytes from 128 to 131072. Using more color depth and higher resolution for connections requires more memory. If the memory limit is reached, the display degrades according to the “Display mode degrade preference” setting.
Related Policies:
* Display mode degrade preference
* Notify user when display mode is degraded
* Maximum allowed color depth
XenApp 6.0 or later and XenDesktop 5.0 or later X X
ICA\Graphics Display mode degrade preference Computer HKLM\SOFTWARE\Policies\Citrix\GraphicsPolicies\DisplayDegradePolicy 0=Degrade color depth first
1=Degrade resolution first
Degrades either color depth or resolution first when the session display memory limit is reached.
When the session memory limit is reached, you can reduce the quality of displayed images by choosing whether color depth or resolution is degraded first. When you allow color depth to be degraded first, displayed images use fewer colors. When you allow resolution to be degraded first, the size (in pixels) of your session is reduced. By default, color depth is degraded first.
To notify users when either color depth or resolution are degraded, configure the “Notify user when display mode is degraded” setting.
Related Policies:
* Notify user when display mode is degraded
* Maximum allowed color depth

XenApp 6.0 or later and XenDesktop 5.0 or later X X
ICA\Keep Alive ICA keep alives Computer HKLM\SOFTWARE\Policies\Citrix\ICAPolicies\SendICAKeepAlives 0=Do not send ICA keep alive messages
1=Send ICA keep alive messages
Sends or prevents sending ICA keep-alive messages periodically. By default, keep-alive messages are not sent.
Enabling this setting prevents broken connections from being disconnected. If XenApp detects no activity, this setting prevents Terminal Services from disconnecting the session. XenApp sends keep-alive messages every few seconds to detect if the session is active. If the session is no longer active, XenApp marks the session as disconnected.
ICA Keep-Alive does not work if you are using Session Reliability. Configure ICA Keep-Alive only for connections that are not using Session Reliability.

ICA\Multimedia Multimedia conferencing Computer HKLM\SOFTWARE\Policies\Citrix\MultimediaPolicies\EnableConferencing 1=Enabled
0=Disabled
Allows or prevents support for video conferencing applications. By default, video conferencing support is enabled.
To use multimedia conferencing, make sure the Windows Media Redirection setting is enabled.
* When using multimedia conferencing, make sure the following items are present:
* Manufacturer-supplied drivers for the web cam used for multimedia conferencing must be installed.
* The web cam must be connected to the client device before initiating a video conferencing session. XenApp uses only one installed web cam at any given time. If multiple web cams are installed on the client device, XenApp attempts to use each web cam in succession until a video conferencing session is created successfully.
* An Office Communicator server must be present in your farm environment.
* The Office Communicator client software must be published on the server.
Related Policies: Windows Media Redirection
XenApp 6.0 or later and XenDesktop 5.0 or later X X
ICA\Multimedia Windows Media Redirection Computer HKLM\SOFTWARE\Policies\Citrix\MultimediaPolicies\EnableRAVE 1=Enabled
0=Disabled
Controls and optimizes the way XenApp servers deliver streaming audio and video to users. By default, this setting is allowed.
Allowing this setting increases the quality of audio and video rendered from the server to a level that compares with audio and video played locally on a client device. XenApp streams multimedia to the client in the original, compressed form and allows the client device to decompress and render the media.
Windows Media Redirection optimizes multimedia files that are encoded with codecs that adhere to Microsoft’s DirectShow, DirectX Media Objects (DMO), and Media Foundation standards. To play back a given multimedia file, a codec compatible with the encoding format of the multimedia file must be present on the client device.
By default, audio is disabled on Citrix Receiver. To allow users to run multimedia applications in ICA sessions, turn on audio or give the users permission to turn on audio themselves in their plug-in interface.
Select “Prohibited” only if playing media using Windows Media Redirection appears worse than when rendered using basic ICA compression and regular audio. This is rare but can happen under low bandwidth conditions; for example, with media in which there is a very low frequency of key frames.

ICA\Printing\Universal Print Server Universal Print Server print data stream (CGP) port Computer HKLM\SOFTWARE\Policies\Citrix\PrintingPolicies\UpsCgpPort   Specifies TCP port number used by Universal Print Server’s print data stream (CGP) listener
The Universal Print Server is an optional component that enables the use of Citrix’ universal print drivers for network printing scenarios. When Universal Print Server is used, printing commands are sent from XenApp and XenDesktop hosts to the Universal Print Server via SOAP over HTTP. However bulk print data streams are delivered to the print server on separate TCP connections using Common Gateway Protocol (CGP). This setting modifies the default TCP port on which the Universal Print Server listens for incoming CGP conections (e.g. inbound print jobs).
This policy must only be applied to OU’s housing the Universal Print Server computers.

ICA\Security Prompt for password Computer HKLM\SOFTWARE\Policies\Citrix\ICAPolicies\PromptForPassword 1=Enabled
0=Disabled
Requires the user to enter a password for all server connections regardless of access scenario. By default, users are prompted for passwords only for specific types of connections. XenApp 6.0 and above (Terminal Server only)   X
ICA\Server Limits Server idle timer interval Computer HKLM\SOFTWARE\Policies\Citrix\ICAPolicies\MaxIdleSessionTimeout   Determines, in milliseconds, how long an uninterrupted user session will be maintained if there is no input from the user. By default, idle connections are not disconnected (Sever idle timer interval = 0). XenApp 6.0 or later   X
ICA\Session Reliability Session reliability connections Computer HKLM\SOFTWARE\Policies\Citrix\ICAPolicies\AcceptSessionReliabilityConnections 1=Allowed
0=Prohibited
Allow or prevent session reliability connections.
Session Reliability keeps sessions active when network connectivity is interrupted. Users continue to see the application they are using until network connectivity resumes.
When connectivity is momentarily lost, the session remains active on the server. The user’s display freezes and the cursor changes to a spinning hourglass until connectivity resumes. The user continues to access the display during the interruption and can resume interacting with the application when the network connection is restored. Session Reliability reconnects users without reauthentication prompts.
If you do not want users to be able to reconnect to interrupted sessions without having to reauthenticate, configure the Auto client reconnect authentication setting to require authentication. Users are then prompted to reauthenticate when reconnecting to interrupted sessions.
If you use both Session Reliability and Auto Client Reconnect, the two features work in sequence. Session Reliability closes, or disconnects, the user session after the amount of time you specify in the Session reliability timeout setting. After that, the settings you configure for Auto Client Reconnect take effect, attempting to reconnect the user to the disconnected session.

XenApp 6.0 or later and XenDesktop 5.0 or later X X
ICA\Session Reliability Session reliability timeout Computer HKLM\SOFTWARE\Policies\Citrix\ICAPolicies\SessionReliabilityTimeout   The length of time in seconds the session reliability proxy waits for a client to reconnect before allowing the session to be disconnected.
The default length of time is 180 seconds, or three minutes. Though you can extend the amount of time a session is kept open, this feature is designed to be convenient to the user and it does not prompt the user for reauthentication. If you extend the amount of time a session is kept open indiscriminately, chances increase that a user may get distracted and walk away from the client device, potentially leaving the session accessible to unauthorized users.
If you do not want users to be able to reconnect to interrupted sessions without having to reauthenticate, configure the Auto client reconnect authentication setting to require authentication. Users are then prompted to reauthenticate when reconnecting to interrupted sessions.
If you use both Session Reliability and Auto Client Reconnect, the two features work in sequence. Session Reliability closes, or disconnects, the user session after the amount of time you specify in the Session reliability timeout setting. After that, the settings you configure for Auto Client Reconnect take effect, attempting to reconnect the user to the disconnected session.

Server Settings\Connection Limits Limit user sessions Computer HKLM\SOFTWARE\Policies\Citrix\IMA\Connection Limits\UserSessionLimit   Specifies the maximum number of concurrent connections a user can establish, in the range 0-8192. A value of 0 indicates no connections.
A user’s active and disconnected sessions are counted for the user’s total number of concurrent connections. When a user tries to establish a connection in excess of this limit, a message tells the user the connection is not allowed. When a connection request is denied, the server records the user’s name and time in the System log.
Limiting connections for Citrix administrators can adversely affect their ability to shadow other users. By default, local administrators are exempt from the limit so they can establish as many connections as necessary.

This setting works in conjunction with the Enable server-side content fetching setting on the user device.
This setting is frequently used when the user device does not have direct access to the Internet. The XenApp or XenDesktop server provides that connection.
The second generation of Flash redirection introduces a server-side content fetching fallback for Flash .swf content files. If the user device is unable to fetch the content from a site and the Flash server-side content fetching URL list is configured and enabled, server-side content fetching seamlessly takes over.

2=High – high definition audio
Specify the sound quality as low, medium, or high.
Select “Low – for low-speed connections” for low-bandwidth connections. Sounds sent to the client are compressed up to 16Kbps. This compression results in a significant decrease in the quality of the sound but allows reasonable performance for a low-bandwidth connection.
Select “Medium – optimized for speech” for delivering Voice over IP applications. Audio sent to the client is compressed up to 64Kbps. This compression results in a moderate decrease in the quality of the audio played on the client device, but provides low latency and consumes very low bandwidth. Currently, Real-time Transport (RTP) over UDP is only supported when this audio quality is selected. Use this audio quality even for deliverying media applications for the challenging network connections like very low (less than 512Kbps) lines and when there is congestion and packet loss in the network.
Select “High – high definitiion audio” when delivering media applications. This setting provides high fidelity stereo audio but consumes more bandwidth than the Medium quality setting. Use this setting when network bandwidth is plentiful and sound quality is important.
Bandwidth is consumed only while audio is recording or playing. If both occur at the same time, the bandwidth consumption doubles.

0=Prohibited
Allows or prevents Citrix Receiver and Web Interface users to see their local special folders, such as Documents and Desktop, from a session. By default, Special Folder Redirection is allowed.
This setting prevents any objects filtered through a policy from having Special Folder Redirection, regardless of settings that exist elsewhere. When you allow this setting, any related settings specified for the Web Interface or Citrix Receiver are ignored.
To define which users can have special folder redirection, select “Allowed” and include this setting in a policy filtered on the users you want to have this feature. This setting overrides all other special folder redirection settings throughout XenApp.
Because Special Folder Redirection must interact with the client device, settings that prevent users from accessing or saving files to their local hard drives also prevent Special Folder Redirection from working.
For seamless applications and seamless and published desktops, Special Folder Redirection works for Documents and Desktops folders. Citrix does not recommend using Special Folder Redirection with published Windows Explorer.

ICA\File Redirection Use asynchronous writes User HKLM\SOFTWARE\Policies\Citrix\<ID>\User\CdmPolicies\UseAsyncWrites 1=Allowed
0=Prohibited
Enables or disables asynchronous disk writes. By default, asynchronous writes are disabled.
Asynchronous disk writes can improve the speed of file transfers and writing to client disks over WANs, which are typically characterized by relatively high bandwidth and high latency. However, if there is a connection or disk fault, the client file or files being written may end in an undefined state. If this happens, a pop-up window informs the user of the files affected. The user can then take remedial action, such as restarting an interrupted file transfer on reconnection or when the disk fault is corrected.
Citrix recommends enabling asynchronous disk writes only for users who need remote connectivity with good file access speed and who can easily recover files or data lost in the event of connection or disk failure. When enabling this setting, make sure that the “Client drive redirection” setting is enabled. If this setting is disabled, asynchronous writes will not occur.

“Set default printer to the client’s main printer” allows the client’s current default printer to be used as the default printer for the session.
“Do not adjust the user’s default printer” uses the current Terminal Services or Windows user profile setting for the default printer. If you choose this option, the default printer is not saved in the profile and it does not change according to other session or client properties. The default printer in a session will be the first printer autocreated in the session, which is either:
* The first printer added locally to the Windows server in Control Panel > Printers

When creating filters for a policy that contains this setting, include all clients specified in all entries in the setting.
By default, the client’s current printer is used as the default printer for the session.
When setting the default printer value:
“Client main printer” allows the client’s current default printer to be used as the default printer for the session.
“Do not adjust” uses the current Terminal Services or Windows user profile setting for the default printer. If you choose this option, the default printer is not saved in the profile and it does not change according to other session or client properties. The default printer in a session will be the first printer auto-created in the session, which is either:
* The first printer added locally to the Windows server in Control Panel > Printers
* The first auto-created printer, if there are no printers added locally to the server
You can use this option to present users with the nearest printer through profile settings (known as Proximity Printing).
“<Not Set>” means that you are not changing the value set by the system or other policies. It equates to a “Not Configured” state for that entry.
When policy settings are resolved, default printers applied by this setting take precedence over default printers applied by the “Default printer” setting.
When setting the session printer value:
You can add printers to the list, edit the settings of a list entry, or remove printers from the list. You can apply customized settings for the current session at every logon. When printing polices are applied, session printers are merged into a single list: all printers applied in all policies that include a “Printing Assignments” setting; and, all printers applied in policies that include a “Session printer” setting.
Use individual “Default printers” and “Session printers” policies to set default behaviors for a farm, site, large group, or OU. Use the “Printer assignments” policy to assign a large group of printers to multiple users.

When you define these rules, you can allow or prevent printers to be created with the specified driver. Additionally, you can allow created printers to use only universal printer drivers.
Driver substitution overrides (or maps) printer driver names the client provides, substituting an equivalent driver on the server. This gives server applications access to client printers that have the same drivers as the server but different driver names.
You can add a driver mapping, edit an existing mapping, override custom settings for a mapping, remove a mapping, or change the order of driver entries in the list. When adding a mapping, enter the client printer driver name and then select the server driver you want to substitute.

1=Retained in user profile only
2=Held in profile only if not saved on client
3=Do not retain printer properties
Specifies whether and where to store printer properties. By default, the system determines whether printer properties are stored on the client device, if available, or in the user profile.
Select “Held in profile only if not saved on client” to allow the system to determine where printer properties are stored. Printer properties are stored either on the client device, if available, or in the user profile. Although this option is the most flexible, it can also slow logon time and use extra bandwidth for system-checking.
Select “Saved on the client device only” if your system has a mandatory or roaming profile that you do not save. Choose this option only if all the servers in your farm are running XenApp 5 and your users are using Citrix XenApp Plugin versions 9.x or later.
Select “Retained in user profile only” if your system is constrained by bandwidth (this option reduces network traffic) and logon speed or your users use legacy plug-ins. This option stores printer properties in the user profile on the server and prevents any properties exchange with the client device. Use this option with MetaFrame Presentation Server 3.0 or earlier and MetaFrame Presentation Server Client 8.x or earlier. Note that this is applicable only if a Terminal Services roaming profile is used.

1=Use universal printing only
2=Use universal printing only if requested driver is unavailable
3=Use printer model specific drivers only if universal printing is unavailable
Specifies when to use universal printing. Universal printing employs generic printer drivers instead of standard model-specific drivers potentially simplifying burden of driver management on host machines. The availability of a universal print driver depends upon capabilities of client, host, and print server software. In some certain configurations, universal printing may not be available. By default, universal printing is used only if the requested driver is unavailable.
“Use universal printing only if requested driver is unavailable” uses standard model specific drivers for printer creation if they are available. If a requested driver model is not available, the system will attempt to create the printer with a universal driver.
“Use only printer model specific drivers” specifies that the printers should not be created with a universal driver. If the requested driver model is unavailable, the printer will not be created.
“Use universal printing only” specifies that only universal drivers should be used to create printers. If a suitable universal driver universal printing is not available, then the printer will not be created.
“Use printer model specific drivers only if universal printing is unavailable” employs a universal printer driver if it is available. If a suitable universal driver is not available, the printer may still be created with requested driver model if it is available.

0=Spool directly to printer
Controls the method of processing the EMF spool file on the Windows client machine. When using the Citrix Universal Printer driver, the system spools the EMF records on the host and delivers the EMF spool file to the Windows client for processing. Typically, these EMF spool files are injected directly to the client’s spool queue. For printers and drivers that are compatible with the EMF format, this is the fastest printing method. However, some drivers may require the EMF spool file to be reprocessed and sent through the GDI subsystem on the client. Normally, this alternate print path is selected automatically. However, since it is not always possible to detect such printers and drivers automatically, this setting can be used to force the EMF spool file to be reprocessed and sent through the GDI subsystem on the client.

Specifies the minimum level at which to encrypt session data sent between the server and a client device.
“Basic” encrypts the client connection using a non-RC5 algorithm. It protects the data stream from being read directly, but it can be decrypted. By default, the server uses Basic encryption for client-server traffic.
“RC5 (128 bit) logon only” encrypts the logon data with RC5 128-bit encryption and the client connection using Basic encryption.
“RC5 (40 bit)” encrypts the client connection with RC5 40-bit encryption.
“RC5 (56 bit)” encrypts the client connection with RC5 56-bit encryption.
“RC5 (128 bit)” encrypts the client connection with RC5 128-bit encryption.
The settings you specify for client-server encryption can interact with any other encryption settings in XenApp and your Windows operating system. If a higher priority encryption level is set on either a server or client device, settings you specify for published resources can be overridden.
You can raise encryption levels to further secure communications and message integrity for certain users. If a policy requires a higher encryption level, plug-ins using a lower encryption level are denied connection.
SecureICA does not perform authentication or check data integrity. To provide end-to-end encryption for your server farm, use SecureICA with SSL/TLS encryption.

ICA\USB Devices Client USB device redirection rules User HKLM\SOFTWARE\Policies\Citrix\<ID>\User\VCPolicies\USBDeviceRules   Lists redirection rules for USB devices.
When a user plugs in a USB device, the host device checks it against each policy rule in turn until a match is found. The first match for any device is considered definitive. If the first match is an Allow rule, the device is remoted to the virtual desktop. If the first match is a Deny rule, the device is available only to the local desktop. If no match is found, default rules are used. For more information about the default policy configuration for USB devices, refer to CTX11972, “Creating USB Rules,” in the Citrix Knowledge Center.
Policy rules take the format {Allow:|Deny:} followed by a set of tag= value expressions separated by whitespace. The following tags are supported:
* VID – Vendor ID from the device descriptor
* PID – Product ID from the device descriptor
* REL – Release ID from the device descriptor
* Class – class from either the device descriptor or an interface descriptor
* SubClass – Subclass from either the device descriptor or an interface descriptor
* Prot – Protocol from either the device descriptor or an interface descriptor
When creating new policy rules, be aware of the following:
* Rules are case-insensitive.
* Rules may have an optional comment at the end, introduced by #.
* Blank and pure comment lines are ignored.
* Tags must use the matching operator =. For example, VID=1230.
* Each rule must start on a new line or form part of a semicolon-separated list.
* Refer to the USB class codes available from the USB Implementers Forum, Inc. Web site.
Examples of administrator-defined USB policy rules:
Allow: VID=1230 PID=0007 # ANOther Industries, ANOther Flash Drive
Deny: Class=08 subclass=05 # Mass Storage
To create a rule that denies all USB devices, use “DENY:” with no other tags.
