Best Answer

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.

Tool location

The DCDiag command-line tool is included when you install Windows Server 2003 Support Tools from the product CD or from the Microsoft Download Center(http://go.microsoft.com/fwlink/?LinkId=100114). For more information about how to install Windows Support Tools, see Install Windows Support Tools(http://go.microsoft.com/fwlink/?LinkId=62270).

Tool requirements
  • Except as noted below, all commands in DCDiag can be run on Windows XP Professional and Windows Server 2003 family (member servers and domain controllers).
  • The new DCDIAG /TEST:DNS command can validate DNS health of Windows 2000 Server (SP3 or later) or Windows Server 2003 family domain controllers when run from the console of Windows XP or Windows Server 2003 member computers or Windows Server 2003 domain controllers.
