So I did something really stupid, forgot the admin password to my server running MS Server 2012. I so rarely shut down and have to log in because my server is running 24/7 that when I lost power and had to log back in, I couldn't remember my password. I'm trying to avoid having to reinstall the entire the OS because of a rookie mistake, mostly because of all the services running on this server. I've downloaded quite a few trial "recovery tools" but these seem to do everything except reset a password. If anyone could guarantee that a particular application works and is worth paying for, I'd be happy to pay for something to save myself the days and days of reinstalling and reconfiguring all the different services. So my question is, what is the path of least resistance to getting full access to my server again?
I regularly use Offline NT Password & Registry Editor:
However, I cannot vouch on whether it works well for Server 2012 or not. As usual, take precautions and perform a backup before attempting this.
This works on Windows Server 2008 R2 and Server 2012 R2. You will need Windows Server 2012 Installation DVD to reset password.
Reset Windows Server Password with Installation CD
Use a third party tool to reset the administrator password. There are a variety of these, which you can find with a trivial Internet search.
I won't recommend any particular tool, and neither does Microsoft:
