2 Nics&Networks -1 Stops Internet - DESPERATE

Specs: XP , Intel
We are replacing an XP workstation with an Win 7 Pro 32-bit workstation.

The XP works fine. It has 2 ethernet cards b/c it attaches to 2 different networks.

1 cable plugs into your DSL Rounter which allow internet access.

The other plugs into a router in the FRONT of our store to access cash register information.

With the Windows 7 workstation this replacing the above XP, it is set up exactly the same (2 nics that are working fine, etc).

However, when the cable that plugs into the Cash Register router up front is attached...We can NO LONGER LOAD WEB PAGES.

Windows Network status shows that we DO have internet on one of the nics....but we suddenly cannot load web pages (it does NOT even show a yellow exclamation point, which usually happens when internet access drops).

I can simply upplugthe cable from the nic (the one that connects to the network upfront)....and sudden, web pages Will load.

Again...I can start up the XP workstation, plug in the same cables...and access both networks AND the internet just fine.

Please Note: cards are set to obtain ip and dns automatically (same as the xp box)...and those address are being assigned just fine.

I have disabled IP6....but that does not make any difference.

We're desperate here...Gotta get this working.

THANKS very much.

Does the NIC connected to the router serving cash register have a Default Gateway configured. If so, delete it.

No...it did not have anything specified. It was set to be completely assigned.

HOWEVER, this is what seemed to solve the problem:

The NIC connected to the cash register network was set to static....and the SAME info that was already being assigned to it was used as the settings.

In other words....I just did an ipconfig /all command to display the settings that were currently being assigned....and manually entered to exact same settings for the NIC.

Why manually entering the Exact same settings that it was being assigned anyway makes a difference... I don't know.
