Preventing DNS registration

[PhilKGH]

How can I prevent a server's secondary network card registering its details on our DNS servers? I have disabled the network connection associated with the card, removed its ip address, and deleted the ip address from the registry but it still keeps registering 10.1.1.2 in DNS. Consequently some users keep losing connection to the server because it is resolving to the wrong ip address.

Regards,
Phil.

Are you referring to a 2nd NIC on the DNS server which is autoregisterting?

If:
-This is a W2K3 server, and
-it is a AD-Interated Primary zone, AND
-you have already checked "Do not register this conenction in DNS" on the DNS Properties of the NIC,

then you can try this reg tweak:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters

Registry value: DisableNSRecordsAutoCreation
Data type: REG_DWORD
Value: 1

This is a DNS client. I was getting two entries on the DNS server for the one client.

I've found the solution now, as follows, taken from

http://support.microsoft.com/?id=246804:

To disable DNS updates for a particular interface, follow these steps:

1. Click Start, click Run, type regedit, and then click OK.

2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ Tcpip\Parameters\Interfaces\deviceID

Note deviceID is the device ID of the network adaptor for the interface.

3. On the Edit menu, point to New, and then click DWORD Value.

4. Type DisableDynamicUpdate, and then press ENTER two times.

5. In the Edit DWORD Value dialog box, type 1 in the Value data box, and then click OK.

6. Quit Registry Editor.

7. Reboot the server.
