Unable to connect to internet outside of LAN using a pc on the domain
NOTE: We use static IP addresses on both our LAN and DMZ
Computer A is joined to our domain and is connected to our LAN, - internet works correctly.
Computer A is joined to our domain and is connected to our DMZ (IP address changed accordingly) - internet does not work
Computer A is joined to our domain and is connected to a 3G air card (IP address set to automatic) - internet does not work.
Computer B is a member of a workgroup and is connected to our LAN - internet works correctly.
Computer B is a member of a workgroup and is connected to our DMZ - internet works correctly.
Computer B is a member of a workgroup and is connected to a 3G air card - internet works correctly.
It would seem to me that there is something in the domain is preventing an alternate connection to the internet. Could this be a GPO, or route setting?

I would look at GPO first. Look at the Windows Firewall and/or Windows Firewall with Advanced Security settings in any GPO that applies to this computer and/or user.
flush the dns cache. check the IP, firewall security settings, and proxy settings (using?)
ASKER
Windows firewall is disabled via GPO. We are not using a proxy.
This may seem like a silly question, but when you changed the IP address for Computer A to move it to the DMZ, did you change the default gateway as well? How about DNS? Can you ping/connect to other computers in the DMZ as opposed to hosts on the Internet, or is there no connectivity at all when in the DMZ?
ASKER
yes IP address, gateway, and DNS are changed when connecting to DMZ.
If the computer is in a DMZ are you sure the computer can connect back to a DC to apply the GPO?
If you tracert to some known internet host (such as 8.8.8.8) when in the DMZ what are the results?

If I were to log on to our DMZ on a laptop that is a member of the domain as a local administrator, the internet does not connect. I think it has to do with a persistent route that was setup in the registry. I'm just not sure how it got there.
