Enabling VPN disconnects normal network from server

[krdshrk]

I am running a server with 2 network cards (both on the same subnet & physical network... with 1 private, and 1 public ip address). Whenever I enable my VPN (configuring through Routing and Remote Access MMC Snap-in) using the wizard, all computers on my network can no longer see (ping/connect to) the server, and from the server, i can no longer see other computers on the network. However, I can still connect to the internet, which is strange. Does anyone know why this is happening?

Computer Info:
Win2k Adv. Server, SP2
NIC #1 - IP: 192.168.1.17 (Private) - 3Com 3C980C-TXM
NIC #2 - IP: 192.168.1.246 (Public - through Router NAT) - D-Link DFE-530TX+
Router - Cisco 1720

Are you just enabling the server to accept VPN connections or are you actually connecting from the server to another box via VPN? Did you happen to set up the VPN connection as a demand dial interface? Are your clients default gateway your server?
