We have had a recurring, and very annoying problem on some of our live servers – when trying to access any folder in IIS called “reports” it was asking for additional login information, and not showing the actual content from the folder. A bit of digging revealed that the culprit was SQL Server 2008 R2 Reporting Services.
Turning off Reporting Services didnt have any effect, we just got a 503 Error.
Click on Start
Type in Reporting Services Configuration Manager
Click on Report Manager URL on the left hand side of the Reporting Services Configuration Manager – by default it is set to “Reports”, as you can see here, we have already changed ours to “SQLReports”
Please leave a comment if this has helped you resolve the same problem we had!
