Use this procedure to reduce the workload on the PDC emulator master by changing the priority for DNS SRV records in the registry.
The Registry Editor bypasses standard safeguards, allowing settings that can damage your system or even require you to reinstall Windows. If you must edit the registry, back up system state first. For information about backing up system state, see Administering Active Directory Backup and Restore.
To perform this procedure, you must be a member of the Domain Admins group in Active Directory.
