Login Failed For User Sa Sql Server 2012
windows authentication I am getting the error: Error 18452 (not associated with a trusted sql server connection) . I added my domain\userName in sql with no problems and https://support.microsoft.com/en-us/kb/555332 added the account to the sysadmin server role. However, I noticed my credentials on my pc are not listed as domain\userName but rather ComputerName\UserName. I think this is what is causing the problem but I am not sure. Can anyone lend a hand? I'd appreciate any help, Thanks.

SQL Server 2000: Go to Start > Programs > Microsoft SQL Server > Enterprise Manager Right-click the Server name, select Properties > Security Under Authentication, select SQL Server and Windows The server must be stopped and re-started before this will take effect SQL Server 2005: Go to Start > Programs > Microsoft SQL Server 2005 > SQL Server Management Studio Right-click the Server name, select Properties > Security Under Server Authentication, select SQL Server and Windows Authentication Mode The server must be stopped and re-started before this will take effect..." http://www-1.ibm.com/support/docview.wss?uid=swg21119906 It has solved my problem, so I hope it could be helpful for you too.
