Dcdiag default tests |
The following table shows tests that run by default. |
Test |
Description |
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. |
CheckSDRefDom |
Checks that all application directory partitions have appropriate security descriptor reference domains. |
CrossRefValidation |
Checks the validity of cross-references. |
FrsEvent |
Checks to see if there are errors in the file replication system. Failing replication of the SysVol share can cause policy problems. |
FrsSysVol |
Checks that the file replication system and system volume are ready. |
FSMOCheck |
Checks that the domain controller can contact a Kerberos Key Distribution Center (KDC), a time server, a preferred time server, a primary domain controller (PDC), and a global catalog server. This test doesn't test any of the servers for operations master 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. |
KccEvent |
Checks that the KCC is completing without errors. |
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). |
MachineAccount |
Checks whether the machine account has properly registered and that the services are advertised. Use the /RecreateMachineAccount parameter to attempt a repair if the local machine account is missing. Use the /FixMachineAccount parameter if the machine account flags are incorrect. |
NCSecDesc |
Checks that the security descriptors on the naming context heads have appropriate permissions for replication. |
NetLogons |
Checks that the appropriate logon privileges exist to allow replication to proceed. |
ObjectsReplicated |
Checks that the Machine Account and Directory System Agent (DSA) objects have replicated. You can use the /objectdn:dn parameter with the /n:nc parameter to specify an additional object to check. |
OutboundSecureChannels |
Checks that secure channels exist from all of the domain controllers in the domain to the domains that are specified by the /testdomain parameter. The /nositerestriction parameter prevents dcdiag from limiting the test to the domain controllers in the site. |
Replications |
Checks for timely replication and any replication errors between domain controllers. |
RidManager |
Checks whether the relative identifier (RID) master is accessible and if it contains the proper information. |
Services |
Checks whether the appropriate domain controller services are running. |
SystemLog |
Checks that the system is running without errors. |
VerifyEnterpriseReferences |
Checks that specified system references are intact for the FRS and replication infrastructure across all objects in the enterprise on each domain controller. |
VerifyReferences |
Checks that certain system references are intact for the FRS and replication infrastructure. |
VerifyReplicas |
