IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.
After your Microsoft Windows NT Domain Name Service (DNS) server starts, you may receive one or more of the following event log error messages:
You may also see your DNS server in the server list of the DNS Manager with a red X on it, indicating that the DNS service is unavailable, and you may see the following message in the DNS Manager:
This behavior can occur when the registry key that determines whether your DNS server initializes from a boot file or from the registry has not been updated properly.
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk
For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.
To resolve this issue, follow these steps:
Start Registry Editor (regedt32.exe) and locate the following subkey:
Edit the following value as appropriate:
Value Name: EnableRegistryBoot Value Type: REG_DWORD Data: 1 or 0 (1 for registry boot, 0 for boot file)
- Quit Registry Editor.
This value is set to 1 when the first zone is created, and by default the boot file's information is then migrated into the registry. When resetting this registry value back to zero, it disables the DNS server from booting or initializing from the registry. If the DNS Server does not boot from the registry, then it must initialize from a boot file. A backup boot file can be found in the following location:
Copy the backup boot file to the %SystemRoot%\System32\Dns folder, and then restart the DNS service.
Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
