The ICA section contains policy settings related to ICA listener connections and mapping to the Clipboard.
Client clipboard redirection
This setting allows or prevents the Clipboard on the user device being 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.
This setting allows or prevents non-administrative users connecting to a desktop session on the server.
By default, non-administrative users cannot connect to these sessions.
ICA listener connection timeout
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
This setting specifies the TCP/IP port number used by the ICA protocol on the server.
By default, the port number is set to 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.
Launching of non-published programs during client connection
This setting specifies whether to launch initial applications or published applications through ICA or RDP on the server.
By default, only published applications are allowed to launch.
This setting enables or disables the copying and pasting of data from the session to the local user device.
By default, this setting is disabled and users can copy and paste data from the session to the local user device and from the local user device to the session.
When enabled, users can cut and paste data only from the local user device to the session.
When enabling this setting, make sure the Client clipboard redirection setting is present and set to Allowed. If this setting is disabled, the Clipboard on the user device is not mapped to the Clipboard on the server, and users cannot copy and paste data between the session and the local user device.
