Two network interfaces, one route to the internet

Posted on 2004-11-10

I have two network cards in a Windows 2000 Server machine.  The first is connected to the internet, and is correctly configured (gateway, subnet, etc.).  The second is connected via a crossover cable to another machine,

Occasionally it seems the routing tables get screwed up and the machine can't determine the correct path to the internet.  Temporarily disabling the 192.168.0.* interface corrects the problem.

Does anyone have any suggestions?  I'd post the output of 'route print' but it wouldn't be of any use, routing is fine right now.

Here is the output of ipconfig:

    Default Gateway is defined as the Route to, by having a Default Gateway on both adapters you are giving it two different routes to Of course only one of those routes is valid... So, remove:

    Default Gateway . . . . . . . . . :

    And it should all work quite happily. is a directly connected network and doesn't require a gateway or anything like that.

    Hope that makes sense to you.
