I have set up a Windows Server 2008 r2 with Citrix Xenapp. We plan to use the web interface, but we are waiting for updated thin clients in order to use the ICA connection. In the meantime, we just decided to use the Remote Desktop function and use it like we would any other terminal server.
When I connect within the Lan, I can connect from the thin clients just fine. When I try to connect from a remote site, I get remote access timed out; try again later. At one site, she was able to log in, but then got kicked out almost immediately.
I checked policies, but I am not sure what to do at this time. We have about 25 Win 2003 terminal servers and they all work fine. What is so different about 2008 r2?
