I have a Windows2000 Server running with two NICs, DLink 528 & DLink 530. DLink 528 is connected to my ISP, the DLink 530 is connected to my internal network. My problem is Windows2000 will switch from one NIC to the other while using the internet. Meaning it will use the DLink 528 for the internet, and the next minute use the DLink 530. What would be causing this? What would I do to fix this?

It looks like adaptive load balancing, or adaptive fault tolerance, check advance properties of the nics and see if these properties are enabled. Just a thought.

I have had the same problem using Win 2000. It seems to choose it's NIC rather randomly for each subnetit sends traffic on. I would try loading RRAS and forcing traffic not on the local subnet out the interface for the internet. You will have to look into the security aspects of this however.

It sounds like you are using your server as a router/gateway. For this to work you must set up RRAS, and a key point here is that the LAN card must not be set up with a default gateway. Also your routing will have to be running. This can be tricky, and I've seen problems with it in the past.
