Dynamic Domain Name Updates

Windows 2000 and XP support dynamic Domain Name System (DDNS) updates and is enabled by default. This setting allows you to control whether network adapters should send updates.

Open your registry and find the key below.

Create a new DWORD value, or modify the value named "DisableDynamicUpdate" and set it to equal "1" to disable the use of dynamic updates.

This can also be controlled on a per adapter basis by modifying the same value at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\ Parameters\Interfaces\[Adapter ID].

Restart Windows for the changes to take effect.


Settings:
System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
Name: DisableDynamicUpdate
Type: REG_DWORD (DWORD Value)
Value: (0 = enable updates, 1 = disable updates)
