Integrated Windows Authectication fails when loading asp f..

Archived from groups: microsoft.public.win2000.security (More info?)

My site is authenticated by Integrated Windows Authectication (anonymus
access is not allowed)
Remote client activate default.asp and inside I have the following client
code that fails
privilegesXMLObj = new ActiveXObject("Msxml2.FreeThreadedDOMDocument" );
privilegesXMLObj.setProperty("ServerHTTPRequest" , true);
privilegesXMLObj.async=false;
var ReturnValue = privilegesXMLObj.load("getPermissions.asp?type=2" );
Why doesn it fail? It seems that original credentials are not passed to the
next asp page? Wnen I enable anonymus access it works but I want it to work
only with Integrated windows authectication
What should I do to fix this security problem?
