Unable to connect to domain without VPN active

I am in the same physical office, on the same physical network, same subnet, etc...

I can ping the server by internal and external IP addresses, but I can only connect with mstsc /v:server_name if I connect to the VPN first. I also cannot find the domain controller when attempting to add a machine to the domain without first connecting to the VPN.

This is fine, except I can't log in without first connecting to the VPN either. Not so fine.

Server 2003 R2 and XP Pro
LVL 9

RRAS  CAN be made to work yes but you have to break lots of things that should be automatically configured by an AD server and configure them manually. The trouble it causes is imense and not worth the hastle.

Also, nslookup -type=srv domain fails unless connected to VPN.

Does your domain controller have Multiple NIC's installed by any chance?

It does not. One NIC on 192.168.0.250.

RRAS shows Loopback, Local Area and Internal. Only dedicated has a device name.
IP Routing > General shows .240 and .250 for Local Area, 100 for Internal

I don't know why 100 is assigned. I can't ping it without the VPN, so I'm assuming that's where the problem lies. .100 is not assigned in IP config as an additional address.

Basically RRAS should NEVER be installed and configured on your DC

It works without RRAS; however, I know that RRAS works on a DC, as I have seen it previously.

We also need VPN access, as we have two sites. I could set another set up as RRAS I guess, but for 5 employees to get in it seems like a waste.
