Error 0xc00002c2

Question

Hi All,
I have a VM with windows server 2016 that is not booting anymore, returning error 0xc00002e2, that I read is related to it being a DC.

The VM has undergone an abrupt poweroff due to the hyperv server being powered off due to blackout. The VM was rebooting and installing updates in that moment

I have walready tried all the most common solutions coming out when googleing 0xc00002e2:

-log in using Directory Services restore mode and renaming all .log files in NTDS folder

-use esentutl to fix the database

-use DISM online cleanupimage restorehealth both from DSRM and by booting from DVD, failing with error 1009 (system registry corrupted)

-using DISM online cleanupimage revertpendingactions, failing with same error

-repeating the previous after restoring windows registry from backup (I saved a new backup first)

The VM still does not boot

Answer 1

Hopefully there's another domain controller to where you can simply seize roles

then perform cleanup before rebuilding it.

Answer 2

I know this procedure, my question was pointed towards avoiding this set of tasks, that is not really feasable to perform at the moment

Answer 3

Maybe this one helps. (the former would be much simpler / safer)

Answer 5

Hello,

Thank you so much for your feedback.

Then I would recommend Dave's former suggestion. Firstly make sure that there is another domain controller where we could seize the roles or to make the AD environment could still work. Then we will demote the domain controller and perform the cleanup. For more information about these, we could refer to the links provided by Dave.

Then we will replicate the changed to all domain controllers in our environment. During the process, we will make sure there is no any error. Check if all DCs work fine by running Dcdiag /v on every DC. And check if AD replication is working properly by running repadmin /showrepl and repadmin /replsum on every DC.

If all work fine, we are able to promote the server as Domain Controller again.
