Non-domain connection problem



Greetings,

I appreciate any insght into this unusual network case.

SUMMARY

When a client PC is physically removed from the domain it cannot access the
Internet unless the VPN software is running.

SITUATION

When users physically remove their PC's from our domain (they take them home
at night) they are unable to surf the Internet from home.
The only way for them to connect to the Internet is to use the VPN client
software.
Once they are connected to our Domain, they can surf!

HISTORY

The domain has two locations 20 kilometres apart. They are connected with a
persistent VPN tunnel. For 10 months users can access resources at/from both
sides.
Users have been able to go home and VPN into the network.
Users were able to connect to the Internet from home without any trouble and
without using the VPN client software.
A MS Server 2003 was installed at the remote site as a local data store.
Since this has been installed, the users cannot connect to Internet UNLESS
the vpn software is running.

SOME TEST RESULTS

PING works from home.
IPOCONFIG shows a local ip address (from a home router).
NSLOOKUP always shows the IP address of the main SBS2003 server.
Hence the need to connect via VPN to get on the Internet.

QUESTION
How do I get my clients to release the IP address of the main SBS2003 server
so that they can surf the net from home?

Thanks for helping,

Liam
