SBS 2003 Standard

Internet Access is fine.  
internal clients are fine.  IPconfigs (i dont have one for clients)  are correct for wins/dns/gateway to the SBS.
here is IP config for the server.

I am able to VPN using the connection wizard or through a manually create connection.  However no internet or network resources are available.  

Also the server logs an error 20209
A connection between the VPN server and the VPN client 68.5.97.138 has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47). Verify that the firewalls and routers between your VPN server and the Internet allow GRE packets. Make sure the firewalls and routers on the user's network are also configured to allow GRE packets. If the problem persists, have the user contact the Internet service provider (ISP) to determine whether the ISP might be blocking GRE packets.

The problem seems to lie in the internal adapter not getting an IP from DHCP.  

Also an IPconfig from a VPN connected client shows an IP and Default gateway of the same IP address. (obviously not going out anywhere through yourself)  I have checked the DHCP scope and the internal clients using DHCP are fine.  I assume this is also bcause the internal adapter cant get an ip.

VPN gre47 PPTP passthrough is set on the router as well as forwarding 1723 to the server.  (also it worked a few days ago)  
This is a new client and I was called in after some "virus removal"
Also seems that this server was mainly managed with "enterprise logic"  Although the wizards seem to be running ok.
