Your post prompted me to give this a try. We're still on Windows 2003R2, and I preformed the following steps: 1. Restored our "master" AD controller to a sandbox2. Booted AD controller and let Veeam complete the "non-authoritative" restore3. On second boot hit "F8" and selected "DSRM"4.
Logged in with DSRM account and password5. Ran "ntdsutil"6.

Users should frequently backup the system state data on domain controllers so that they can restore the most current data. By establishing a regular backup schedule, there is a better chance of recovering data when necessary.
