Only one XP computer can't establish VPN
Our client is running VPN server on Windows 2008 server. All users and computers can establish the VPN except one XP laptop. Here are symptoms on this computer. 1. When trying to establish their company VPN, the computer gets error 638. 2. If we setup a VPN to access my company VPN running on windows server 2008, it works. 3. On the same XP computer, if I establish the VPN to my company VPN server first and then connect to their company VPN that works fine (meanng there are two VPN connections). 4. If I try clean boot on the computer, the VPN to their company error is 800. 5. I have deleted and all VPN settings and re-do it, but that doesn’t help. 6. I can telnet port 1723 from the computer. 7. The VPN serer doesn't have any related errors in the Event Viewer. Any suggestions?
