First published on TechNet on Feb 13, 2015 Tom here with a quick Friday update... Here's something that we hope you'll never need, but has become an unfortunate necessity. Jared Poeppelman, one of our colleagues over in Microsoft Consulting Services has built and tested a great PowerShell script for resetting your KRBTGT password.
