This is probably a ServerFault.com question really, after all if the code is working fine then its not a programmatic problem.

Also update from other sources like your anti-virus supplier (Sophos had this problem) can break MSXML installs.

Another ProgID to try is "MSXML2.ServerXMLHTTP.6.0" after having installed MSXML6. If the problem is with an update to the MSXML3 core then perhaps the MSXML6 core doesn't have the same problem.
