Remote Desktop stops working after one use

Hi,

We have a Server 2008 R2 Server we are connecting to with Remote desktop.

After one use, the connection becomes unavailable. If we reboot the box we have Remote Desktop works great...for one use.

There is very little installed on this box as it is going to be one of our test servers once we resolve this issue. But it is up to date with patches, etc.

We do not see any interesting items in the Event Log, nor do we get any indication why this happens.

Has anyone seen a similar issue, or know the fix?

THanks
