Hi all. I'm having a networking problem that's stumped everyone I've gone to for help.

I'm on a network at work, and am connecting to another network via VPN. I'm trying to Remote Desktop into a computer over the VPN with a local IP (192.168.1.85).

When I first connect over VPN, I can connect via Remote Desktop but as soon as I interact with the computer at all, the connection is lost. It doesn't appear to be an RD problem, however, as demonstrated by a follow up test. I connected the VPN, no problems. I immediately pinged that IP and all 4 pings came back fine. I pinged again, all 4 came back fine. I pinged again, 3 came back fine and the 4th timed out. Then all pings after that timed out. I disconnected and reconnected the VPN and had similar results, only it wasn't the 12th ping that timed out again (in other words, it's not consistent).

In short, it seems like my VPN connects fine but shortly thereafter it disconnects itself. I have no idea why. No errors are raised and I'm having a difficult time trouble shooting this.

The only option I changed from the default options for the VPN is "Use default gateway on remote network" in TCP/IP advanced settings. I turned this off, on the advise of our tech guy. I'm running XP Pro w/ SP2, fully updated. I have Norton AV auto-protect on but it behaves the same with it off as well. I've disabled my firewall.

Can anyone help? If you need more info just ask. I just got done with a fresh reinstall and it's still not working.

Is there a wireless router involved in there anywhere?

Nada. That is to say, not in my network. As for the remote network, I don't know - would it help if I found out?

Our network is on a T1 connected with a Covad modem, connected to a Netgear FS116 switch.

I don't remember if I mentioned this already or not, I don't think I did... but others on my network are able to RD in without any problems. They're also running a fully updated XP Pro with all the same connection settings. You can see why I'm baffled here..

Yup, I see why. Has it ever worked on the problem machine?

Nothing jumps out at me, so just throwing out ideas here:

Check and see if your local system time is accurate. Maybe a lease timeout?

Verify permissions in the Local Security policy of the remote machine. Maybe you have permmisions on the VPN server but not file access/system management permmisions on the remote machine you are connecting to?
