Sorry in advance for the noob question.
I am trying to learn to mirror a test database and in the course of doing this, was typing in some commands into a query box. While trying to create a database mirroring endpoint I submited a command with a typo. I was returned an error. I tried to resubmit a corrected command, but then was told that the endpoint already existed. So then I figured I'd just delete my test database and restart. I deleted the database in my primary sql server, but now my mirror sql server shows my test database as restoring, and I am unable to delete that one.
Is there a way to undo everything that I have done, going back to a installation default of my sql server? There is nothing I need to save, I'm just trying to learn stuff.
