I have installed SQL Server 2012 on my Windows 10 computer. When I try to access Reporting Services via the Browser such as Chrome or Firefox, It prompts me for username/password (In which I do enter) but then it gives me an error
(Reporting Services Error: The permissions granted to user 'ComputerName\User' are insufficient for performing this operation. (rsAccessDenied)).
I have tried many solutions such as Internet Options and SQL server management studio. I have spent most of my time trying to figure this out but have given up hope.
