The setup:
-Server 2012 R2 configured for HA.
-GPOs configured for session time limits on both client and RD Hosts.
SERVER GPO (applied to RDHost servers)
USER GPO (applied to clients)
Users get the "Disconnected Due toTimeout" message every 2 hours. They are able to reconnect to their disconnected session and pick up where they left off without re-authenticating, etc. so I know those policies are working.
I have also tried manually setting the timeout via the registry on a client, configuring a Keep-alive via GPO, manually setting the timeouts on the session hosts and changing the timeout in IIS for the RDWeb Gateway (even though internal clients are set to bypass the gateway).
What am I missing? Thanks in advance.
