JSI Tip 3598. How do I prevent Windows 2000 from attempting DDNS on my Internet NIC?

To prevent Windows 2000 from attempting to Dynamically register a selected Network Interface Card (NIC):

1. Use Regedt32 to navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TCPIP\Parameters\Interfaces\<interface>.

2. Edit or Add Value name DisableDynamicUpdate. Toggle the Data type to REG_DWORD. In the DWORD Editor, set the data value to 1.

NOTE: You will notice that HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TCPIP\Parameters\DNSRegisteredAdapters only contains subkeys for the registered adapter(s).

NOTE: See tip 2428 » How do I prevent a domain controller from dynamically registering DNS names?
