Remote Desktop Probem - Vista to Terminal Server 2003

I have working on this problem for very long time. My problem is when Vista
remote desktop connect to the server 2003, I found the remote session has
been established in Terminal Server. But there is no session return back to
my Vista and there is a time out error message being prompt later. I have
checked there is a error message being logged in my Terminal server.

I have already tried to turn off the firewall and anti-virus program, but
situtation are the same.

Does anyone know why is happened?

Note: I have not problem when using windows XP remote desktop.
