VPN Set Up Stops My Exchange Server

I am trying to set up a VPN and everytime i get through the intial set up of routing and remote access my Exchange Server stops functioning. I am totally confused. I am setting up the VPN on the Secondary DC so why would it affect my Exchange Server. I end up having to restart System Attendant and the Information Store or sometimes rebooting all the way. I'm also confused about the 2 NICs for VPNs. I have no idea if i am doing it right because i have never even got through setting it up all the way. If you have any detailed instructions or websites please let me know.

Well, everyone says that their outlook stops working. So i check the server and when i open up the mailbox store in Exchange System Manager i can't see any mailboxes. So the first thing i do is restart services ( System Attendant and Information Store). Both times that i have had problems have been when i finished the Routing and Remote Access Portion of VPN setup on my DC. It also seems i have to disbale the second NIC on the DC before the services will restart. I think i am doing something wrong there but i am very unfamiliar with VPNs.

Yea, a bunch. On the DC there are 2 months worth of "windows can not query the list for group policy objects".

On the Exchange server the strangest one i can see says "All Global Catalog Servers in use are not responding: DC.mydomain.loc"
That one occurs right when i am setting up the interfaces and RRAS for the VPN on the DC. Weird...
