I have a very odd scenario that Im hoping someone can help me answer. I have a Windows 2003 Server Network with a Sonicwall T170 firewall. I have a Windows 2000 user who connects remotely using the Global VPN Client. He never has a problem getting a connection to the VPN and I can see him on my end. However, after a few minutes, he can no long ping our Domain Controller or Exchange server. I can still see him once this has happened but he cant connect to his email, etc.. In order to fix his problem, he has to reload (import) the lmhosts.sam file in the properties of the SonicWall Virtual Adapter and then, he is okay for a while until he has to do it again. This is very cumbersome but, he does it. We have tried everything we know to try, including contacting SonicWall which was absolutely no help.
Now for the REALLY ODD thing &&.I connected to his computer (via his Internet connection not VPN) using PCAnywhere Version 10. While I am connected to him, doing nothing but watching him work (he loads be a host and I connect), everything works PERFECTLY his connection never drops and everything runs very fast. I tested this to be sure that it really did work better only when PCAnywhere was connected. I disconnected and he soon lost his connection. I then reconnected for several hourse and everything worked like a charm.
How can this be? I dont understand? What is PCAnywhere doing is it somehow using my host file for his connection? I am running Vista.
Thanks for any insight you can give me on this.
