Privacy policy. You administer an AD environment. Starting test: SystemLog The event log System on server dcdiag Starting test: VerifyEnterpriseReferences The following problems were found while verifying various important DN references. Note, that these problems can be reported because of latency in replication. You run DCDiag and it returns a failure that names can not be resolved.

You should now get a passing test when you run dcdiag. Like this: Like Loading April 6, at pm. Paul Tassell says:. November 29, at pm. Runs this test only. The Connectivity test, which you cannot skip, is also run. Tests the connection between the domain controller on which you run the command and the source domain controller. This parameter is used for the CheckSecurityError test.

SourceDomainController is the DNS name, NetBIOS name, or distinguished name of a real or potential server that will be the source domain controller for replication, as represented by a real or potential connection object. In addition, creates an inventory report based on the test results. Domain controllers and DNS servers that are offline will increase run time as a result of long-time out periods for RPC and other protocols. Presents extended information about successful test results, in addition to information about errors and warnings.

The tables in this section show tests that you can run by using dcdiag. The tests are grouped into the following categories:. Replications Checks for timely replication and any replication errors between domain controllers. NCSecDesc Checks that the security descriptors on the naming context heads have appropriate permissions for replication. Advertising Checks whether each domain controller advertises itself in the roles that it should be capable of performing. This test fails if the Netlogon Service has stopped or failed to start.

KnowsOfRoleHolders Checks whether the domain controller can contact the servers that hold the five operations master roles also known as flexible single master operations or FSMO roles. Intersite Checks for failures that would prevent or temporarily hold up intersite replication and predicts how long it would take for the Knowledge Consistency Checker KCC to recover. Results of this test are often not valid, especially in atypical site or KCC configurations or at the Windows Server forest functional level.

This test does not test any of the servers for operations master roles. RidManager Checks whether the relative identifier RID master is accessible and if it contains the proper information.

MachineAccount Checks whether the machine account has properly registered and that the services are advertised. CheckSDRefDom Checks that all application directory partitions have appropriate security descriptor reference domains.

VerifyReplicas Checks that all application directory partitions are fully instantiated on all replica servers. VerifyReferences Checks that certain system references are intact for the FRS and replication infrastructure.
