A. Windows can store DNS start-up information in one of three possible locations. The OS records the location in the DNS BootMethod registry subkey by using the following values:
- 1—In a BIND-style file (%SystemRoot%\System32\DNS\Boot); the system still checks the registry for missing data in the file. Windows 2000 DNS doesn't support this option.
- 2—In the registry.
- 3—In both the registry and Active Directory (AD).
- Start regedit.exe.
- Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS.
- View the BootMethod value and compare it to the three options listed above.
- Close regedit.
Note that if you upgrade from Windows NT 4.0 to Win2K, you need to check this value after the upgrade. If you haven't applied Service Pack 4 (SP4) to NT 4.0, the system should use an alternate key, EnableRegistryBoot, until the DNS service populates the correct key.
