How to Reset SQL Server SA Password if You Forgot it

August 5th, 2012 by Admin Leave a reply »

I have a local install of SQL Server Express that I haven’t touched in months. Now I need to use it, and I’ve forgotten the SA password. I have tried using SQL Server Management Studio, I have done Single User Mode with SQL Server and used sqlcmd, they all tell me I don’t have permissions for it. I’m afraid that even reinstalling SQL Server Express isn’t going to fix this for me. Does anyone know of any other method to reset the SA password?
