Recovering access to a SQL Server that you don't have 'sa' access to anymore
It's happened to most all of us at one time or another; an instance of SQL Server has been inherited where no one knows the sa password, or is a member of the sysadmin role, it's annoying when it's a SQL Server instance on a Development or Test server, but becomes far more problematic when it's on a production system. Fortunately, there's a way to solve this.
