The SRV resource records for a domain controller are important in enabling clients to locate
the domain controller. The Netlogon service on domain controllers registers this resource
record whenever a domain controller is restarted. You can also re-register a domain
controller’s SRV resource records by restarting this service from the Services branch of
Server Manager or by typing net start netlogon. An exam
Question might ask you how to troubleshoot the nonregistration of SRV resource records.
