When I inherited our SQL Server databases, the correct 'sa' password was not handed down. From other posts, I'm pretty sure I know how to change the 'sa' password, but what I do not know how to do is determine which (if any) applications, jobs, etc. are using the 'sa' account to connect. I do realize it is bad practice, but wouldn't be surprised if there are applications using the account.
So... how can I find out what applications, jobs, etc are using the 'sa' account before I change the password and break something?
