The server authentication is set to:
SQL Server and Windows Authentication mode
I can connect using Window authentication but not SQL authentication.
Login failed for user 'sa'. (Microsoft SQL Server, Error: 18456)
Error Number: 18456 Severity: 14 State: 1
I have reset the sa password and started and stopped the serveries to no avail.
I also created a new login. No dice.
There as a process on another computer that was stuck in a loop. Once I killed the process I was able to login. I don't know why or how. But that is one only thing that I know of that changed.
