I have taken over management of a remote desktop environment running on Server 2008. Client computers at a remote office log in via RDP to the server to use its applications. At a certain time each evening, all remote users are logged off automatically, and apparently locked out (I need to double check on this). I need to adjust the time, but cannot find a group policy or setting that is currently applied. The domain controller runs server 2003, and I have looked through all of the group policies as well as settings on the 2008 server.
I'm not sure what to look for or where to look next - any ideas?
