I recently installed SQL Reporting Services 2005 without a problem. So I thought. After installing the software I ran the configuration tool, and found that I could not access the reportserver site. I was prompted for a password and no matter what passsword was used, including Administrator I would continue to be prompted.
After some research I remembered during the install of IIS I was prompted for the Windows Server 2003 CD. I provided the CD and the files required were not found. I ended up needing to use an I386 folder I had on another server. I thought that was wierd but it did get installed. I found out that the software being used was from 1 CD and the software on the server was from another, as I had cloned an image to the server. Long story short is I had to re-apply Windows Server 2003 Service Pack 2. After a reboot everything worked.
