AS long as the VPN is set up to use TCP/IP and remember that

Read their AUP.


Also Windows 2K servers on which Exchange server sits needs RPC (Port 135) to function properly so although it can be protected it can t be actually "Closed".

"Would it be possible to prevent the attack by disabling the RPC service?

It is not practical to disable the RPC service on a Windows 2000 server. RPC is an integral part of the Operating System and many services will not function with RPC disabled."
