Microsoft URL Control - 6.00.8862 is NOT a Microsoft robot, it is a "control" that allows programs running on Windows to access the web. You might want to check over in the Search Engine Spider Identification forum or do a site search for more info. This user-agent is on many "block lists" as a possible e-mail harvester or site-grabber.
