After installing VPN on a MS 2003 server it discontected from the domain.
When I ask active directory to browse for the domain it finds it but when i
ask it to connect to it I get the specified domain either does not exist or
could not be contacted.
The ADSL modem has no NAT or DHCP
2nd router with NAT (WAN public IP, LAN private IP
I have 2 NIC's in the server
NIC 1 public IP default gateway ADSL modem
NIC 2 private IP deafult gateway the 2nd router

As said in other post, it is not recommended to enable two NICs in a DC. Otherwise, you may have connectivity issue or name resolution issue. You can setup VPN using just one NIC and you need to do NAT or port forwarding. These links may help,

To add to Bob's remarks, you can get this sort of problem even if the
machine only has one NIC. As soon as your first remote client connects, the
RRAS internal interface gets an IP an becomes active (because this is the
endpoint of the VPN link). So once more you have a multihomed server.

The way to fix it remains the same. You need to make sure that only the
"main" IP address of the server is associated with the server name.
