Mulithoming a Windows 2003 Domain Controller for a backup system

Hey guys i have my regular network connection in all of my servers as well as a second nic card with a seperate IP Subnet range and gateway and on a different switch and it is all gigabit. The reason i am multihoming is so the network wont get bogged down from the data transfer.
Anyway all of the servers operate 100% fine and the backups are flawless. I only have one problem. The domain controller runs
DNS also and everytime i activate the second Nic card i loose internet connection through that DNS server.
What can i do to eliminate this. I dont understand what the problem is that is causing this. I assume there is some sort of conflict between the two networks i am running and the DNS.
Anyway i have the NIC card disabled but i cant back up the DC which is a very important backup.
Thanks for your help in advance
Also just for arguments sake.
The main network is a class A subnet and the secondary network is a class C subnet

Create DNS entries for the secondy network. - Short Answer

Your PDC is controling the primary network and it is failing when you startup the secondary because it's not sure how to handle it.

What you can do it setup a SDC on another box for the secondary network.

So like say my backupserver i could set up DNS ?
Is that what you are saying?
Or are you saying on my main DNS server which is the DC create host records for the secondary network?
Or are you saying set up a new fwd and reverse lookup?
Not sure what  you meant by that.
thanks again

jjeffords,

Sorry I shouldnt write coments before my first cup of coffee...

You can setup a new machine for the Secondary Domain Controler for the secondary network.

and or

Create host records on the primary for secondary network, with the forward and reverse lookup zones.

Sorry should have made myself more clear the first time around.

Hey no problem at all i appreciate your help
This is what i did though
I created a new fwd and rev lookup on my primary dc but that did not work. It still fails on the internet.
However i did no manually add any host records under the new lookup zone
Do i need to do that
Also what would i name the new zone on the fwd side? Same as others two zones (IE onslow.org and onslowmemorial.org)
or would i make a whole new name up for the zone?
Anyway thanks again

Use a new name for the zone... Other wise you might get conflicts with the records when a DNS is accessed...

what i did was name the zone backup2k3
with the a records though
do i need to manually add those?
or wait for them to fall into place
Also would the zone be a primary? I would say yes but i am not sure

Also are these other servers now going to have to be a part of a new domain name?
Just curious
First time i have ever had to deal with this
Thanks

Yes the zone should be a primary.

Yes manually add them to the primary.

The other servers that were always working should continue to work on the old domain.

jjeffords ,

Okay Lets try something really dumb... (Yes I know we should not have to do this... ) It worked for three minutes... So we now have proof of it working with this configuration...

Can we try a warm boot on the DNS please... Cause this should be working... Grrrrr.......

Rebooting server now.
Now i am assuming my LAN settings should be on exg2003 which is the DC should be
192.168.1.11    ip
255.255.255.0   submask
192.168.1.1   gateway


Now should the gateway be 192.168.1.1
That is the Overland Storage units IP addy or should it be the same as the dns(exg2003)
also shouldnt the DNS be 192.168.1.11 (exg2003)
?
