Scenario:
I have installed SQL Server 2008 R2 and configured Reporting Server. When I log in to Server, I am able to access reports but when try to browse the reports from other computer/s, It prompts for User Name and password again and again. After trying 3,4 times it shows nothing or display 401 error.Solution :
The quick solution for this is to remove
If you have installed your SQL Server to different Directory then try to find there.
