RRAS NIC Knocking Out Local Access

[Guest anthony@necrofiends.com]

I'm running a VPN using Routing and Remote Access on a SBS 2003

Server. It has worked fine for months. Today local users weren't

able to access the server unless the RRAS NIC was disabled. Users

connected through the VPN could still access the server without any

issues. No new software or updates have been installed. I'm kind of

puzzled. How do I fix it?
