Description

Determines the source of information that the Domain Name System (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 BootMethod entry has replaced this entry. If this entry appears in the registry, DNS uses its value to set the value of BootMethod, and it 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 in this file, but it 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.

Activation method

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 Image Note

This entry is included in the registry for compatibility with Windows NT 4.0 and earlier. For Windows 2000, use the BootMethod entry.

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 it began storing values in the registry as soon as the DNS snap-in was used to change a value that affected the boot file. For more information, see the Windows NT 4.0 Resource Kit.

Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
