JSI Tip 9968. How do I prevent a DNS client from registering PTR resource records (reverse lookup) on all network adapters?

When you want forward lookup registrations but not reverse lookup registrations:

1. Open a CMD.EXE window.

2. Use REG.EXE, built into Windows XP and Windows Server 2003, or from the Windows 2000 Support Tools, to type the following command:

REG ADD "HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters" /V DisableReverseAddressRegistrations /T REG_DWORD /F /D 1

3. Shutdown and restart your computer.

NOTE: There is no registry entry to disable PTR resource record registration on individual adapters.
