Can you post some specific details, because I would expect there to be a few. If you looked at my system, you'd see Windows Time Update, Windows Update, Adobe Acrobat Updater, Java Updater, Microsoft Money, Symantec AntiVirus, and Outlook sending data. I imagine there's some sort of network discovery/uPNP processes, also.Just sit down and run a packet sniffer for a few days, then do a reverse DNS lookup on some of the IP's that you find... Look at some of the packets that are being sent, what type they are, and where they are going.... It's some pretty interesting stuff to say the least...
