401 Error ServerXMLHTTP/Integrated Auth Problem

Hi,
Hopefully there is a solution to this one.


1 Server 2003 standard edition, thus IIS6, setup to use Integrated +
Basic authentication. Anonomous access is turned off for the target
page.


Code is as folows and produces a 401.1 error


Dim objXmlHttpCat, strURL
strURL =
strUnSecureURL&"/admin/order/i­nvoiceprint.asp?noadminlogin=t­rue&noprint=true&ID="&id&","

Set objXmlHttpCat= Server.CreateObject("Msxml2.Se­rverXMLHTTP.4.0")
objXmlHttpCat.open "GET", strURL, False, "username", "password"
objXmlHttpCat.send ""
strBody = Replace(objXmlHttpCat.Response­Text, "?", "")
Set objXmlHttpCat = Nothing


However when I turn off Integrated auth (thus using basic) it works
fine and retrieves the page.


I have not got a proxy server and have tried running proxycfg -d and
proxycfg -d -p " " "*" to no avail.


I assume that ServerXMLHTTP can work with Integrated auth, but how do I

go about setting this up?


Am at a loss after much scouring...


Thanks for any help.
