Allow client connections

Use this policy to enable or completely disable connections from the Citrix Receiver.

When this policy is not configured, the client will allow connection to servers.

When this policy is enabled, the client will only connect to a server if the "Enable client" option is selected, and if its version number is greater or equal to the "Minimum client version".

When the policy is disabled, the client will not allow connections to any servers.


Troubleshooting:
If a connection is refused because the client is not enabled, the error message " ERROR: Cannot connect to the Citrix XenApp server. The Server (…) is not trusted for ICA connections. Connections to the (All Regions) Region are not allowed by lockdown settings. Please contact your administrator." appears.

If the client does not allow a connection because the version number is too low, the error message "Error number 2321: ICA Client Configuration Manager: The ICA Client version is too low to run using the installed configuration data." appears.

Supported on: ADMX Migrator encountered a policy that does not have a supportedOn value.
