I tell you what, Carol Bailey is a writing machine. She had another article that posted yesterday that covers requirements, how to verify the installation, and even some troubleshooting tips for the fallback status point. If you need to get one of these setup then you’d do well by stopping over at the Configuration Manager Team Blog and checking it out:
Thanks to a recent Configuration Manager TechNet forum posting, I realized that we hadn’t documented the prerequisites for the fallback status point, apart from saying that it required IIS. When we released Configuration Manager 2007, we didn’t support Windows Server 2008, and configuration for IIS was much simpler. Consequently, I’m not aware of any problems installing this optional site system role on IIS 6.0.
