Microsoft.XMLHTTP: error (0x800C0005)

code:

<%

Set xml = Server.CreateObject("Microsoft.XMLHTTP")
xml.Open "GET", "http://users.pandora.be/hts/error", true
xml.Send


Set fso = CreateObject("Scripting.FileSystemObject")
Set MyFile = fso.CreateTextFile("c:\err.txt", True)

MyFile.writeLine(xml.responseText)
response.Write (xml.responseText)

MyFile.Close
%>

this is a known script for retrieving the content of a webpage
when I ran the script the first time (localhost) I had error (0x800c005)
When I loaded the "http://users.pandora.be/hts/error" en ran then the script again all seems ok
when I changed the content of "http://users.pandora.be/hts/error" the asp page showed me the content of the previous error file.
When I cleared the cache again I received error (0x800c005)

is there a way to preload "http://users.pandora.be/hts/error" on serverside or there an other way?

thanks
