I am having the same issues. In ASP, I am creating object for 
Microsoft.XMLDOM and then using the object, I check the whether the xml file 
is existing and is a valid xml file and then set the object to NULL. Then 
also, after some days of running IIS Server, I am facing the issue of Memory 
Leak. Does this has to do with IIS or the version of XMLDom ?
