I have a similar problem. I have been using SME server VPN for years and have been using windows remote desktop protocol over it to access client PC's. Since installing updates on 05/10/08 I have been having a problem. The VPN appears to connect fine and I can run puTTY and networked programs over it, but when I attempt a RDP session, I get the RDP drop down at the start but then it just hangs and eventualy times out with a " connection has been broken" error. RDP is using port 3389. Has something been changed with a recent update to affect this? Any help is greatly appreciated.
