I have a set of Server 2008 R2 Xenapp 6.5 vmware VMs that were recently cloned. I am unable to RDP to these servers. The RDP connection appears to open- flashes a black screen- then closes immediately before asking for credentials with no error message or event log entry on their the source or destination server. RDP is running on 3389 and I am able to telnet to that port. I validated that the server is able to see licenses from our RDS licensing servers (I even removed and re-added the license servers). The RDP-Tcp listener is set to use any network connection. I also recreated the RDP listener. Windows firewall is not running on the target server. Citrix/ICA sessions to the servers work just fine.
Any help would be appreciated.
