I am hoping you can help me although this might be awindows issues. My system administrators are unable to resolve this so I am hoping someone may have dealt with this issue before.

I am running Windows Server 2012 with SQL Server 2014 SP2CU8 and all is well

We have configured a security audit within SQL Serverthat is set to
A: On Audit Log Failure – Shut down server
B: Audit Destination – Security Log

So in order for SQL Server to be able to write to theWindows Event – Security log we gave the account that runs the SQL ServerService full control to the “Security” folder in the registry HKLM\SYSTEM\CurrentControlSet\Services\EventLog\Security.
Also the account we are using is a virtual serviceaccount generated by SQL server.

The problem is that every once in a while when rebootingthe sever The virtual service account NT SERVICE\MSSQL$instance is dropped fromthe “Security” folder permissions. Then of course when SQL server cannot write to the Security Log it shuts down theservice

Has anybody seen this issue before. I know that the system administrators are constantlyimplementing new security procedures via GPO and they are always installingWindows patches.

Any feedback is appreciated.

This issue has shown up again.
Again the networking group installs windows updates and after rebooting theserver my SQL Instance starts and immediately shuts down

To help figure out the issue I will be uninstalling the updatesand installing them back one by one and rebooting after each install. Once complete I hope to figure what or if theKB is causing this issue.

I will let you know.

I found out that KB4088876 - Security Montly Quality Rollup for Windows Server 2012 R2 for x64-based system caused this problem. It happened while both uninstalling and installing the KB. We will now pick this update appart to determine why this is happening and why it happened both in February and in March.

Awesome... You asked the question and you're answering it with some pretty good stuff. Thanks for taking the time, Jeff!

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
