Active Directory Health Check Tool

So here's a little gem that will tell you just about everything you never wanted to know about your AD infrastructure. It pipes the results to a .txt file for easy and thorough review, and also gives a very general sense of health by comparing the number of PASSES and FAILS. I strongly recommend reviewing the resultant c:\ad_diag .txt file in detail to get a more accurate perspective of your AD health. Many of the utils don't report in a pass/fail format, so reviewing the output file is a must for the real picture.

Make sure you have the Server Resource tools for your server platform installed:

Windows Server 2003 Resource Kit Tools
Windows 2000 Resource Kit Tools for administrative tasks

You can download the Active Directory Health Check Tool, ready to run as a .bat, here.

Or, for the more cautious, copy and paste the text below into a .txt file, save as .bat.

In either case run it on your FSMO domain controller to get a real good picture of the status with your AD. None of this stuff is intrusive, mostly verbose versions of the command line diags for AD. Enjoy!
