NoteHKLM\SYSTEM\CurrentControlSet\Services\DNS\Parameters
| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 0 |
Determines the source of information DNS uses to start, such as settings to configure DNS, a list of authoritative zones, and configuration settings for the zones.
In Windows 2000, the EnableRegistryBoot entry has been replaced by BootMethod. If EnableRegistryBoot appears in the registry, DNS uses its value to set the value of BootMethod, and then uses BootMethod thereafter.
| Value | Meaning |
| 0 | File. DNS searches for startup information in a standard, BIND-style file called Boot in the Systemroot\System32\DNS directory on the local hard drive. DNS uses the information defined in this file, but looks in the DNS subkeys in the registry for any startup information that does not appear in the file. |
| 1 | Registry. DNS starts only by using the server configuration and zone information stored in the registry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS. It does not use a boot file. |
DNS reads its registry entries only when it starts. You can change entries while the DNS server is running by using the DNS console. If you change entries by editing the registry, the changes are not effective until you restart the DNS server.
Note
This entry is included in the registry for compatibility with Windows NT 4.0 and earlier. For Windows 2000, use BootMethod.
The default startup behavior of the DNS server, as described above, applies only to Windows 2000 and Windows NT 4.0 with Service Pack 4. Prior to Service Pack 4, the DNS server started by using values from the boot file, but began storing values in the registry as soon as you used the DNS snap-in to change a value that affected the boot file. For more information, see the Windows NT 4.0 Resource Kit.
