Verify Active Directory Replication

  • Article

Applies To: Windows Server 2008, Windows Server 2008 R2

You can use this procedure to verify that Active Directory replication is functioning properly on a domain controller.

Membership in Domain Admins, or equivalent, is required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).

To verify Active Directory replication

  1. Open a Command Prompt as an administrator: On the Start menu, right-click Command Prompt, and then click Run as administrator. If the User Account Control dialog box appears, provide Domain Admins credentials, if required, and then click Continue.

  2. At the command prompt, type the following command, and then press ENTER:

    dcdiag /test:replications

Note

For more detailed replication information, use the /v option. 

If this test fails, open Event Viewer and check for errors in the Directory Service log. Use the information in the ActiveDirectory\_DomainService replication events to troubleshoot the problem.
