I hope I've selected the correct StackExchange for this question. I have searched google and StackExchange but haven't been able to find an answer to my question with the search queries used.
I setup a home server as a little project to learn the basics of the Windows Server environment in October 2015. It has worked well and served the purposes I set it up for since.
However, I made a mistake a couple of weeks ago....
Imagine for a second that someone could be stupid enough (or just had a complete lapse in concentration!) to remove 'Full control' for the Administrators on the primary data HDD.
Is there any way to revert this permission change short of reinstalling the OS?
Thanks
