The IIS setting for in server 2003 web edition with ASP.NET version did changed to 2.0.50727.

System.Web.Extensions with version 3.5.0.0 exist in C:\windows\assembly folder as well..

Is anything left beside for the setting above need to check?

But when we try to deploy it into another web server 2003 standard edition, everything is working fine.

Is anyone facing this problem before? and any solution to solved it?
