Hello Adam,
It seems that we need to make a reference to a required dll, this error generaly occure while system tries to refer a COM dll and its dll is not registered through regsvr32 method, as you are creating an instance [Set objDOMDoc = Server.CreateObject("Msxml2.DOMDocument.4.0") ] maybe required dll of it is not registered, we need your inputs here as I need to see it runing before purchase. I have Windows 2003 Enterprise Server runing IIS 6.0. BTW didn't you get such issues from your other users? Why are we having this issue please solve it.
Thank you,
Imran Jaitapker
