Couple days ago i installed Reporting Services on one computer and it worked perfectly. Something happened and i ended up having to reinstall reporting services. In the last screen of the installation, it said "setup could not initialize report server" and that i have to go do it manually. When i tried accessing http://localhost/reports, i get a Windows Authentication login window (which i didn't get when it worked fine) and upon authenticating i get the error message "
The request failed with HTTP status 401: Unauthorized.
 ". Please advise.
