If you are having issues with monitoring and reporting, review these settings….
NOTE: Monitoring and Reporting, and Backup snapin in Server Management communicate with the IIS Default Website using 127.0.0.1. Make sure 127.0.0.1 port 80 is availalbe and no host header is assigned to 127.0.0.1. SBS2003 Premium: <Typically ISA is installed and thus Default Website is bounded to the internal IP only.> Go to IIS, Default Web Site, Web Site tab, Advanced. Server should have the internal IP on port 80 and 127.0.0.1 on port 80. If the loopback is missing, click Add, and type 127.0.0.1 for the IP, 80 for the port, and do NOT assign any host header to 127.0.0.1.
