I've encountered a problem that I can't quite understand. I have two customers with the same problem.
The environment is based on 2003 SBS with a 2008 RDS. All clients are Windows 7
A couple of days ago I get a call telling me that they no longer can log on to the terminalserver.
An account failed to log on.

Log on as domain admin, no problem.
Logging on the termianl server as the user from SBS2003, working!!!
Now trying to log on as the user externally, also working!!!
After that being done, no more logonproblem for the user. It also works with starting a user session from the terminal server.
Can anybody explain this behaviour to me?
