Windows 2008 DC with multiple NIC's DNS

I have a Domain Controller that is also a file server.  We're adding an iSCSI connection to it for a large data repository but the iSCSI connection keeps showing up in DNS.  We have unchecked the checkbox in DNS to update DNS for that connection and do not have any DNS servers on that interface.  Any way to prevent this?  Obviously the downside is that if users resolve to the iSCSI interface, they won't get access to the server as it's on a dedicated VLAN.

Thank you,

Have you tried deleting the DNS record to see if it comes back?

If the record was created, before you removed the option to register in DNS then this would already have been present.

Go this link it is for Windows 2000 but it works the same in Windows 2008 Server.

Make DNS listen to one IP address.

I recommend though not to have multiple network cards in DC.

You can try adding a domain suffix to the 2nd NIC that is not the same as your production network. e.g. backup.local
We've used a similar fix for creating a backup network with 2nd NIC's that didn't register in production.

@2Cs - Yes, we've deleted it several times.  It always reappears within minutes to a few hours.

@dariusg - While I agree that multiple NIC's in DC is less desirable.  I think that iSCSI on the LAN might be more - less desirable...  I'm checking out those links now

@dvt_localboy - that might be the most elegant solution, I'm checking it out.  

I should know in a couple hours which worked best.  Thanks guys.

Not less desirable but unsupported by MS to have a DC with multiple IP addresses.
