Well, I get 100% utilization as well. I'm running W2K Pro with SP1 and the latest updates. It uses 100% of cpu utilization whenever I'm doing a file transfer with icq or g6ftp. I've got high bandwidth, so there is plenty to go around. I also have "low" settings for connections to servers or uploading. I've got the latest version of Gnotella as well. Any ideas? Thanks. davidasekoff@mediaone.net
