I just installed SQL 2012 onto a new W2012 server along with SSRS. Today when I was on that server and went to http://myserver/Reports
it tells me i do not have sufficient access to view reports. Now I am logged on as the same domain admin that installed SQL the day before. If I go into SSRS Configuration and Report URL and click on the link there SSRS fires up just fine. I discovered that I had to add the specific domain admin user under Folder Setting and Site Settings in order to get the page to appear in IE. Why did I have to do that? Why wasn't the domain admin account that had installed SQL not part of the BUILTIN\Administrator group in SSRS?
