Object Required -- Error Code 424

I recently set up a classic asp project on Windows Server 2008 R2.  The project is working fine on production server.  When moving to new server, it comes with Error code 424 on one page, Microsoft VBScript runtimeerror, "Object required" message.

On the page, there is a place using CreateOject function: CreateObject("MSXML2.ServerXMLHTTP").  I wonder if I miss any configuration on IIS which can cause this error.  On error log showed.  Page showed in log as code 200.

I appreciate your advise.
