Windows 10: no event 5136 recorded in DC - Windows Server 2012 R2

I'm using Windows Server 2012 R2 as DC. And I have enable audit policy: Directory Service Changes - Success.Besides, I also checked dsa.msc -> domain, and set the audit as following selection for Everyone,This object and all descendand objects:Write all propertiesModify permissionsBut when I modified some attributes of a user, there was no event 5136 recored in Event Viewer. That's why???

Event ID 1 Event Record 94672 Source WSH on Windows Server 2012 R2

I'm trying to find information on how to solve event viewer Event ID 1 Event Record 94672 Source WSH on Windows Server 2012 R2. I've not been able to find any pointers as to what is generating this error. This server is used as svn repo and when these
event viewer error appears it refuses connections until the server is restarted. Any pointers will be appreciated. Thanks!

IF you want to try seizing the FSMO roles to see if it will help, here is a quick guide (this should be done on the DC you want to keep):

Knowing that this is a DC now I'm really convinced that something is wrong with the AD account for this particular server. It's possible that the promotion to a DC didn't work correctly leaving you with a sort of broken DC.

A reboot is always worth a shot; has that been tried Ahhzz? If it has, then the next step would be to demote this DC and rejoin it to the domain. Once rejoined you can run DCPromo again. Microsoft best practice is to have at least 2 DCs for redundancy.

 

Convert Windows Server 2012 R2 Evaluation to Windows Server 2012 R2

I have purchased the product key of Windows Server 2012 R2. Now the server is on Windows Server 2012 R2 Evaluation. I found a few links there they explained on how to convert from Windows Server 2012 R2 Evaluation to Windows Server 2012 R2 with valid product
key. One of the example is this link:

How to activate Windows Server 2012 R2 Evaluation - Nicolas Ignoto, CTP

Is this a correct way to do? If I follow this step, will my data be erased?

I want to avoid formatting/fresh Windows install because there are some software in the server that we do not know how to backup. We just want to get it activated now, backup will be sorted out later.
