Thanks for looking at this, and thank you in advance for any answers!
I am attempting to start a mirroring session, but I am getting an Error 1418, which basically states that the TCP port doesn't exist. However, when I look at the SQL Logs, I am seeing a completely different error. It says that the login does not have CONNECT permissions on the endpoint.
Here is the problem, I do not know where this Login is coming from. It doesn't exist. It's never existed. It's not the login that I am using when connecting to either the Principal or the Mirror.
I can't create this login because there is a '$' in it, which again, makes no sense. Any help would be astronomically appreciated! Thank you.
