ICA Policy Settings

Website Visitors:

The ICA section contains policy settings related to ICA listener connections, mapping to the Clipboard and custom channels, connecting to server desktops, and controlling the launch behavior of non-published programs.

ICA listener connection timeout

Applicable products: XenApp; XenDesktop

This setting specifies the 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.

ICA listener port number

Applicable products: XenApp; XenDesktop

This setting specifies the TCP/IP port number used by the ICA protocol on the server. The default port number is 1494.

Valid port numbers 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 Receiver or plug-in that connects to the server.

Client clipboard redirection

Applicable products: XenApp; XenDesktop

This setting allows or prevents the Clipboard on the user device to be mapped to the Clipboard on the server. By default, clipboard redirection is allowed.

To prevent cut-and-paste data transfer between a session and the local Clipboard, select Prohibit. Users can still cut and paste data between applications running in sessions.

After allowing this setting, configure the maximum allowed bandwidth the Clipboard can consume in a client connection using the Clipboard redirection bandwidth limit or the Clipboard redirection bandwidth limit percent settings.

Desktop launches

Applicable products: XenApp

This setting allows or prevents non-administrative users to connect to a desktop session on the server. By default, non-administrative users cannot connect to these sessions.

Launching of non-published programs during client connection

Applicable products: XenApp

This setting specifies whether or not to launch initial applications or published applications through ICA or RDP on the server. By default, only published applications are allowed to launch.
