won't hold DNS settings

[langleymass]

We have two Windows 2003 Enterprise servers. Each server has two network cards on two different networks, <192.168.x.x> and <143.166.x.x>. They have static IP's, and I have tried to enter the DNS and the WINS for both network cards.

For the <192.168.x.x> interface, I enter DNS and WINS servers with <192.168.x.x> addresses. For the <143.166.x.x> interface, I enter DNS and WINS servers with <143.166.x.x> addresses.

Unfortunately, after any reboot, the DNS and WINS settings on the <192.168.x.x> interface change to <143.166.x.x>. This has happened several times.

How do I make the server hold the DNS settings? I have seen this work on other machines.

The problem is that your machine will not know which DNS to query if they both have the same weight. If they have the same weight, the system will automatically revert to primary interface settings, which in this case seems to be your 143 interface.

You need to say to your machine, for the following domains (internal domains) go through the 192 interface. For any other domains (most likely external domains) go to the 143 interface.

So do your config again, except this time, configure the domain lookup aswell. I am pretty sure it will do the trick.

How and where exactly do I configure that?

I have another Windows 2003 Enterprise server that does not have this problem. It is on another domain, however. Their settings basically match.

Basically this is creating issues for our backup software. The <192.168.x.x> network is 1 Gbps. The <143.166.x.x> is 100 Mbps.

I am not a Windows administrator, so this is just a guess.

On your 192 interface, configure all your DNS settings and in the window "append these DNS suffixes", put your internal domain. Also in "DNS suffix for this connection" put the internal domain.

On your 143 interface, configure all your DNS settings normally. Don't put any specific DNS suffixes anywhere.

That's how i would try it. Let me know if it works.
