I have installed SSRS on a server which is also both a domain controller and a DNS server and am having some difficulty setting up permissions.
The symptom is the "User does not have required permissions" message, the solution for which is well documented online (e.g. Reporting Services permissions on SQL Server R2 SSRS).
However this solution is not working for me. I have opened IE as administrator and added my domain user with full privileges under both site settings and folder settings, yet still I can only open Report Manager when I open IE as admin, and furthermore when I do so I can only open it with via localhost and not via the machine name.
I suspect the issue may be related to the fact that the server is also a domain controller and a DNS server but really don't know.
EDIT: I should expand on what is happening when I enter the machine name: I am being prompted for credentials 3 times and then getting a blank screen.
