I've been searching for this problem all day. For some reason I get the error:
User 'DOMAIN\USERNAME' does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed.
when I want to go to localhost/reports with my normal user account (it is administrator). I tried all different ways posted on the internet and it still doesn't work.
As a last resort I tried to create a new user account on my pc with admin rights. And voila, it works. I run IE as administrator and I can connect to localhost/reports.
Now, why in the world cant I connect to the report server on my main account? Obviously it is an admin and I run IE as administrator.
I realy hope any of you can help me.
Greetings
PS: also, when I try to go to localhost/reportserver i get the error: The permissions granted to user 'DOMAIN\USERNAME' are insufficient for performing this operation. (rsAccessDenied)
