I have a Windows 2003 (Std Edition) R2 server, which is on the only DC in my domain, and also hosts DNS, DHCP, Exchange, file & print.
Up until recently I have been logging into it via RDC without any delays. However recently whenever I connect I see my credentials flash up and then disappear again, then the screen turns grey and it just sits there for about 5 minutes before the desktop eventually appears.
I have a login script that is running, but that hasn't changed recently so I can't see that being the problem. DNS is set up properly, and the problem occurs if I connect using hostname or IP address, so I don't think it's a DNS issue. Other domain administrators experience the same problem as me, and none of us are using roaming profiles, so I don't think that's the issue.
There are some errors in the event log relating to SQL server, but I can't see these affecting the login times?
Any suggestions would be extremely welcome.
