Looks like I am in for another SQL level issue. Once I install Service Pack 2 for SQL Server 2008, I receive following error whenever I want to access SSRS Home Page:
The above message happens in spite me being having access both to IIS and also to SQL.
Two ways you can suppress this error message:
1. When you run Internet Explorer with “Run as Administrator” mode, then this error do not occur.
2. When you disable Windows UAC, which is not recommended AT ALL.
