I was attempting to setup a network domain by adding the roles DNS Server and Active Directory Domain Server roles to a windows 2008 server that I had previously setup. Note on the machine computer I had already installed SQL Server 2008 R2 which I later found out you should not do. So I uninstall the two roles. But now my SQL Server will not start\run when using an user account I setup for it to run under. It will now only run using the local system account which is not a problem. However the windows authentication logon to the database engine no longer works either. I can only logon to the database engine using SQL server login account SA. What do I have to do to get the SQL Server service to run under a user account again and how do I get SQL Server database engine to login using the windows authentication account to work again? I am trying to avoid a uninstall\reinstall of SQL Server 2008 R2 because I do not want to lose any of my SQL Server Analysis Server (SSAS) cubes that I had previously created.
I tried to run a repair on the SQL Server instance and received the following failure.
