How to clear DCDIAG Errors

Nathan Simon Nathan Simon Profile: Nathan Simon

What is DCDIAG you ask?

This command-line tool analyzes the state of one or all domain controllers in a forest and reports any problems to assist in troubleshooting. DCDiag.exe consists of a variety of tests that can be run individually or as part of a suite to verify domain controller health.

Let’s get back to clearing the errors, one might say that this is a difficult task. Not so much.

Just open up Eventvwr and clear the logs, re-run dcdiag and the errors should go away.

You could also try running dcdiag /fix to let it apply safe fixes.
