I'm trying to configure VPN on a windows 2000 server (SP2). The problem may be a result of trying to configure it over Terminal Server, but I don't know.
Basically, I go through the wizard and it says: "Starting Routing Service" (or whatever it tries to start) and then Terminal Server hangs and I can't get back in. If I log on locally to the box, it can't talk to any of the other computers on the network. The SMTP and POP servers running on my mail server (qmail running on linux) on the same segement of the network also fail to function properly. Other services such as HTTP and SSH on that and other boxes continue to function properly.
I have to unconfigure VPN, reboot all servers and routers and clear all ARP tables before my network functions normally again.
