[Pc_Support] VPN Troubleshooting Reference

[Tim McDonough]

I'm searching for a reference to aid in troubleshooting a VPN problem. 
Any leads appreciated. The MS KB isn't much help.

We have three remote workers who run WinXP Pro and make remote 
connections to access data on a Windows 2003 Server running the VPN 
server.

Last Friday the office in Charlotte started having problems. Soon 
after she launches the connection it disconnects. This usually happens 
about 10-20 seconds after she starts. She can connect to the same 
computer with a secure ftp and transfer huge files with zero problems. 
She has no other Internet troubles either. The other users see no 
problems at all. They run Windows XP as well.

I have done the following so far:

- Walked her through creating a new connection (same problem occurs)
- Had her connect as a different user (same problem occurs)
- Connected from another location as her (everything works fine)
- Had her do several file transfers to and from the same machine 
(works fine)

We do not have a second computer at her location.

I have little experience troubleshooting these connections. I've used 
them quite a bit but this is the first problem I recall having.

Pointers to good reading material, suggestions, etc. are welcome.
