At my office there are various Win XP running Systems connected to Windows 2003 Server Running VPN services and all are running fine. Recently I bought a laptop which came with Vista, I connected the same as well to this VPN network successfully. I was able to use Remote Desktop / Ping / Use Outlook without any problem. But it remains for about an hour and the connections drops automatically.
It happens every hour. Surprisingly when I check the connection with ipconfig, it shows that I still have remote IP but all traffic has stopped, ping tests fails, unable to connect remote desktop. Even outlook says it has lost connection to the Exchange Server. When I open Network and sharing center, I can see VPN connection still connected but as actually it is disconnected according to other test, when I try to disconnect the same, it opens a new pop up saying “Attempting to Disconnect from VPN” and freezes here. The only way to get out of this freeze is to restart explorer.exe
One surprising thing is that all XP computers are still working fine without any connection drop to the same VPN network. Than whats the problem with this Vista? Somebody please help.
