When attempting to log on with a domain account on a computer joined to a domain that has both 2012R2 and 2003 domain controllers, you may encounter the following error:

Error message
unknown username or bad password

Additionally, an Event ID 4 on Source: Kerberos is logged. You can only log on using local accounts.


Mixed 2012R2 and 2003 AD environments require hotfix 2989971 to be installed on every 2012R2 DC. See the KB for a full explanation.

The hotfix requires Update 1 (2919355) to be installed first. The hotfix is also included in update rollup 2984006.

Lingering objects in Active Directory are a pest, and require a lot of work to properly dispose of them. Luckily, there's repldiag.exe, part of Active Directory Utils. This particular tool resolves lingering objects by automating the required procedure and set of commands to run to clean up lingering objects.

In normal circumstances, you would have to look up and run various commands to completely clean out the AD database on each DC. Using repldiag.exe does the hard work for you by looking up the DC's and running the clean up on each DC, cross-referencing with the other DC's, and it does so by using the built-in commands and API's (such as those used by repladmin and other commands).
