I installed an additional NIC in one of my servers last night for a iSCSI connection. I assigned it IP addressed and made the mistake of not unchecking the Register in DNS box. I realized my mistake this morning and unchecked the box but the address keep reappearing in DNS. How do I block it or track where it is coming from. I have multiple DNS servers in each site.

Try this registry edit:  

To disable A and PTR resource record registrations that are performed for a specific adapter, use the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<Interface name>\DisableDynamicUpdate

Data type: REG_DWORD
Range: 0 - 1
Default value: 0

Probably will need a reboot.

Create the DisableDynamicUpdate reg DWORD key and give it a value of 1 under the specific interface's name.

And that won't affect the other interfaces?  I'm only concerned because this is the main Exchange server.

No,  that registry key forces you to recognize and change only the target nic.

This server was a DNS server itself which I did not realize would make a difference.
