Hi

This is actually managed in Group Policy for Windows XP. If you're in a
Windows Server 2003 domain, it will also have the functionality in the
system.adm file. For a Windows 2000 domain, you'll need to manage the group
policy object from a Windows XP client with an administrator account and
load the Windows XP system.adm file.

Policy setting is found in:

Computer Configuration -> Administrative Templates -> Network -> DNS
Client -> Dynamic Update.

Looking at the system.adm file, this appears to map to "RegistrationEnabled"
in "HKLM\Software\Policies\Microsoft\Windows NT\DNSClient". Referring to:

834440 The SetDynamicDNSRegistration method of the
http://support.microsoft.com/?id=834440

The static registry key is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<NetworkAdapterGUID>

Kind regards
