I need to be able to remote desktop to a Windows 2008 machine and then from that machine connect to our corporate L2TP VPN. However, as soon as the VPN connects, the remote desktop session hangs and I need to reboot. I assume this has to do with the machine getting its routing table updated when it connects to the VPN. Is there any way to do this? I have full admin control over both machines.
My guess is that the VPN connection is configured to use the gateway on the remote network (VPN network). Try disabling that option in the VPN properties.
