Blue Screen of Death STOP 0x00000051

24/9/2013

Appreciate there are a lot of errors and possible causes associated with BSOD, however I thought I would share our latest error incase anyone else comes across it.

Symptoms: Occured on a Hyper-V Server 2008 R2 Virtual Machine with Server 2008 R2 OS.

When logging into the server via RDP or at the console, the above 'Blue Screen of Death' appears with error *** STOP: 0x00000051 (click to enlarge)

WinDbg on the dump file gave the following information: probably caused by ntkrnlmp.exe (nt !RtlStringFromGUID+4fb5 )
This was logged with Microsoft.

Cause:
From the Memory dump, it was apparent that System was in the process of syncing the current control set (control set 1) to last known good (control set 2). While doing so it detected inconsistency in \registry\machine\system\ControlSet002. This initiated the crash. (Basically a corruption in the registry)

Resolution:
Create a new LastKnownGood Configuration in the registry, which
can sync with Current Control set correctly. We should change ControlSet002 (currently LastKnownGood) to failed, and create a new ControlSet003(new LastKnownGood)

Steps to do this:
Boot failed server in Safe Mode. Open the registry HKEY_LOCAL_MACHINE\SYSTEM\Select
Change LastKnownGood to 3
Change Failed to 2

Reboot the server into normal mode and hopefully log in succesfully!

Just adding my thanks to you (and Google for getting me here). Had an important VM just up and start continually crash for no reason, nothing changed in months, no clue where to start but your fix got it back up in minutes.

I have a windows server 2008 R2 sitting inside a Hyper-V environment running on a Windows server 2008 R2 server and when i log in i get the 0x0000051 error and all my parameters basically match yours...you might have just saved me a load of work tonight. If you have, me love you long time!

Dean, hope it works for you. Let me know how you get on.

Perfect, absolutely perfect. I used remote registry to edit the registry of the server in question, changed the relevant registry entries to what you had above. I rebooted (as i wanted to back up the VM just in case it was dead after the above change) then restarted the HyperV, logged into the VM......and all i know about the problem is a message from windows helpfully telling me "it recovered from a blue screen!" IT RECOVERED?!?! er no, alex heer's advice implemented by Dean is what recovered it! ;)

I am very appreciative of this page, and you have saved me a lot of work. :D

I am off to click an advert of two...if you have any!

I had the same issue since the recent Windows Update got installed on our server this weekend. Your solution worked just great. Thank you! That saved my day today.

Wanted to chime in and say thank you. This resolved the issue for me on a windows 7 pro VM running in parallels on mac osx (my client).

Thanks very much for this, resolved the issue for me on a 2008 R2 VM on a 2012 R2 Hyper-V host.

This solution was simple and an absolute life saver. After working on a very very similiar problem, where the moment I logged in, it would crash and give me that stupid 0x00000051 error, for 40+ hours straight, 7 hours with a senior Microsoft Technician and another 5 hours with a Dell technician, to have this problem solved by the change of two numbers in the registry blew my mind! Thank you so much for taking the time to post the solution to this horrible, time wasting error that the people who wrote the code don't know how to fix! Keep up the good work! I hope abundance and happiness visits you often.

Ran across this blog post after running some updates on a 2k8R2 VM and getting the BSOD. Very odd, but yours was the fix!

Very grateful

Thanks mate. You did it! It is working again...

Thanks so much for this post! Your solution worked for me on a physical 2008 r2 install. Any idea what the underlying cause of this problem is, or how to prevent it from happening again in the future?
