Folder called Reports requires extra username and password?

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.Resolution:Click on StartType in Reporting Services Configuration ManagerClick 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!
