Two NICS, Two IP Addresses - ONE SERVER NAME

[Guest]

Setup - Internet monitoring system setup w/ two NICS each has a seperate IP
address (both in same subnet). Only one has default gateway setup - problem
is that it's automatically getting registered in DNS w/ two IP addresses for
same name which is causing sporradic problems. Any ideas on how to configure
this in DNS to eliminate the DNS confusion?

Thanks in advance!

Two ways to resolve this.
Add this registry value:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters
On the Edit menu, click Add Value, and then add the following registry
value:
Value name: PublishAddresses
Data type: REG_SZ
Value data: Specify the Internet Protocol (IP) address of the interface you
want the record for.
-or-
You can also use the listener IP address on the Interfaces tab, DNS will
only create the host for the IP address listed, but if you want DNS to
listen on all IP addresses and create only one record use the registry
entry.

This article explains the issues and how to disable autoregistration
globally or for a specific adapter:

Multiple NICs on the same subnet is not normally a useful configuration
in any version of Windows Server. But possibly with a diagnostic setup
you have some need for it?
