Vista Remote Desktop locking / freezing

Can someone please tell me what is with Vista Business Remote
Desktop? I am trying to connect to a Vista Business box via remote
desktop. It works for a login, then if I disconnect and try to
reconnect after a little while, I get the "Welcome" page indefinetly.
If I physically go to the machine that I am remoting into, the screen
says "Please Wait" and is locked there until a hard reset of the
system.

I don't understand this problem at all, and its very annoying, as well
as unsafe as I have to physically reset the machine to get it working
out of the "Please Wait" page.

Please any help would be appreciated.
