dual nics and isolation

[whitebomber]

It seems that when a machine has dual nics it likes to share that fact with other machines. Here's my scenario:

I have a server, ServerA, with two nics. One with a 150.102.x.x address to the corporate network and one with a 10.x.x.x address for a private network.

When I map a drive to another server, ServerB, over the 150.102.x.x nic it also seems to share the fact that it has a 10.x.x.x interface too. Where I see this is on ServerB. If I do a netstat command on ServerB, I will see both ServerA addresses at the time of mapping the drive and periodically at other times.

Is there some way to setup ServerA so that the two nics are totally isolated from each other. Basically that the 10.x only ever needs to communicate with 10.x machines and the 150.102.x would be the interface to use for any other type communication

Thanks.

Make sure you have your subnets set properly. Also you should check what you might have set for a gateway.

I am assuming these are static addresses.

Yes these are static addresses. The 150.x subent has a gateway, dns and wins. The 10.x has NO gateway, dns and wins.

From the perspective of the 150.x subnet, I would like to hide the fact that the 10.x subnet even exists.

In a generic sense I have a machine with 2 nics. One is on the corporate backbone, 150.x and one is using 10.x private addressing. The 10.x is only used to load code to machine controllers on the 10.x subnet.

As an example what I don't want happening is that when I map a drive to a server on the corporate backbone, I don't want the 10.x adapter to be advertised as a potential path.

Hopefully that makes things a bit clearer and I do appreciate the help.
