HTTP 500 errors are being generated on a system that was connected to the Win2K8 Package Servers. These package servers are 32-bit and 64-bit running IIS 7. This is an error specific to the Task Service on the Win2K8 PS’s. Clients that generate this error will probably have a hard time getting “tasks”.

HTTP 500 errors


This is related to the “Integrated” or “Classic” pipeline mode for the application pool in IIS 7.


ASP .NET runs in Integrated Managed Pipeline mode by default on IIS 7, so run the following at the command line - this migrates the configuration to the system.webServer/handlers section

%systemroot%\system32\inetsrv\appcmd migrate config "Default Web Site/"

or change the pipeline mode on the default Application Pool from "Integrated Managed" to "Classic"
