You want to verify DNS is configured correctly so that a domain controller can register its resource records, which are needed for clients to be able to locate various AD services.
This test is available only with the Windows Server 2003 version of
With the following
dcdiag command, replace
dc1 with the DNS name of the domain the
domain controller is in. This command has to be run directly on the
domain controller you want to test.
dcdiag /test:RegisterInDNS /DnsDomain:
Starting test: RegisterInDNS DNS configuration is sufficient to allow this domain controller to dynamically register the domain controller Locator records in DNS. The DNS configuration is sufficient to allow this computer to dynamically register the A record corresponding to its DNS name. ......................... dc1 passed test RegisterInDNS
