Tom,

This might be an authentication issue. Did you try to use proxycfg.exe?
http://support.microsoft.com/default.aspx?scid=kb;en-us;830605

From ASP.NET please do not use Msxml objects as there are known issues of 
doing that.
Please see http://support.microsoft.com/default.aspx?scid=kb;en-us;815112 
for more info.

Instead use managed HttpWebRequest class, documentation for that can be 
found at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemNetHttpWebRequestClassTopic.asp

Regards,
- Umut Alev [MSFT]
