Data type


Default value


0x0–0xFFFF 0x0–0xFFFF



Specifies the priority of this domain controller. The priority determines the order in which clients contact a domain controller. A value of 0x0 represents the highest priority, and a value of 0xFFFF represents the lowest priority. The highest priority domain controller should be contacted first. Lower priority domain controllers are used only when those with higher priority are not available.

When domain controllers have the same priority value, their priority weight, as specified in the value of the LdapSrvWeight entry is used to determine the order in which they are contacted.

Note Image Note

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

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.

Net Logon records the value of this entry on the LDAP SRV records that it writes. You can view these records by using Domain Name System (DNS) dynamic update or by viewing the netlogon.dns file ( Systemroot \System32\config). Also, if the value of DBFlag is 0x2080FFFF, Net Logon records the LDAP SRV records in its debugging log, Netlogon.log ( Systemroot \debug).
