I have installed SQL Server 2008 R2, and was able to login and also create a database and everything.
When I was facing some problems with connecting my .NET project with SQL Server, I created some new accounts in SQL Server.
For some reason I uninstalled it. But later when I re-installed, I was not able to login with the "SA" account. I still see a few of the other user accounts that I created earlier.
Is there any way to completely uninstall SQL Server 2008 R2 and successfully install new copy and login?
