Terminal Server; Very Slow Login and Logoff

I have a "Windows Server 2003 R2 Enterprise x64" server running Terminal Services. Suddenly it started taking a long time (about 1 minute or two) when users logon/logoff. When a user executes RDP they get the login screen is less than a second. After the enter their credentials the entire screen stays blue or gray for at least 1 minute. When the users logs off the Winodws "logoff" prompt stays on the screen for a couple of minutes. If I login from the console the login/logoff process is immediate (about a second or 2). Windows is not reporting any errors in the Event Viewer.

I took the following steps and they did not improv the speed at all:
I installed the x64 version of uphclean 2.0.
I deleted all profiles older than 60 days.
I verified that no group policies were mapping folders or roaming profiles. In fact there are not any group policies enabled.

Are there any entries in the application or system eventvwr that stand out to you? Is there anything in login scripts that could be causing this?

The only errors that show up in the Sys EV are for printers that are not setup on the TS. The App EV shows up clean. There are no login scripts associated with this server.

I looked at the hotfix but I dont have IE 7 installed on the server. I was willing to try it anyway but the hotfix is not available for download for a x64 system.

This TS is one out of two servers used for load balancing on the same application. I just noticed that if I delete a profile on the working server the newly created profile is less than one 1 MB. If I do the same on this server the newly created profile is 18 MB!
