I've been running a web site for the past year on Windows Home Server 2008 R2. After the March 2012 system updates, the site is no longer accessible to clients. They see this error: website is online but isn't accepting connections.

Ping tests to the FQDN of the server are successful and NSLOOKUP returns the correct result. The Internet connection tests out good from the server. I have not changed my internet connection (Comcast Business Internet) or my router configuration (I forward incoming requests from the outside to port 80 of the local IP address of the server).

I have tried:

  • Disabling the Windows Firewall.

  • Rebuilding the OS and configuration.

I still have the problem. How can I resolve this?
