Description

Determines whether this domain controller registers DNS A (IP address) records for the domain. If this domain controller is a global catalog resource, then this entry also determines whether the domain controller registers DNS A records for the global catalog.

Value Meaning
0 Does not register DNS A records. LDAP implementations that do not support SRV records will not be able to locate the LDAP server on this domain controller.
1 Registers DNS A records.

Note Image Note

This entry is used only when it appears in the registry of a domain controller.

You might consider setting this value to 0 if DNS fails to complete its dynamic updates because it cannot update A records. DNS stops updating when an update attempt fails.

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.
