Cannot logon to Terminal Server

[kendaukcat]

Hello all.

Here is my issue...

I have a user that can log on conventionally from a fat client. He can also logon to other servers on my domain that are running in remote administration mode after I add the user to the domain admins group.

However, when he tries to logon to my terminal server (in application mode) he gets the customary : The system could not log you onm make sure your username and password or correct, blah blah blah, caps lock is not accidentally on, blah blah blah message. He even cannot logon when left in the domain admins group.

I have verified that the user is allowed to logon to terminal server, the account is not locked out, and other users are able to logon to the terminal server successfully.

I have even matched group memberships with a successfully logged on user to make sure it is not a permissions issue.

There is nothing in the event viewer security log.

Any ideas?

Thanks,

Ken
