Old FAQ number: 1003
The symptom of this issue is that after installing the MS03-32 Security Update on a Windows XP machine, all requests to ASP.NET applications running on the local IIS 5.1 web server result in an error message saying "Server Application Unavailable". Requests to remote web servers are unaffected. It does not impact machines running Windows 2000 or Windows Server 2003. It also does not impact machines running Windows XP with ASP.NET v1.1 installed.
This is a bug in Windows caused by the above mentioned security patch, please visit the ASP.NET site for more information:
