Hi Gianluca, thanks for the reply.

I am simply using the windows VPN, the kind that you create in Network 
connections.  The server that I VPN into is just a Windows 2003 Standard 
Server with RRAS setup on it.  So everything is built-in windows 
stuff... no 3rd party software.

I will do this, but I just want to make sure before I do that I am not 
making some simple mistake.  If you could give me any further info I'd 
appreciate.  If you need it, also, I'd be happy to post my test code.  
Please let me know.

Thanks,
gm
