If you're just curious about the traffic, there are some things you can do. Off the top of my head, and in no particular order: a)go to Computer Management and expand the Shared Folders branch. Look at Sessions and Open Files to see if any clues jump out. b)from a Command Prompt, run "netstat -a" to see what connections are open. c)in Task Manager, select the Networking tab and look at the Network Utilization to see how much traffic is involved. d)pull the WAN cable from the router to see if the traffic stops. If it stops, it was LAN-WAN traffic. If it doesn't stop, it's LAN-LAN (intraLAN) traffic. Not a definitive test, but helps determine where the endpoints may be. e)use a packet capture program such as Wireshark to view the actual traffic. This will allow you to see the source and destination IP's and ports, the traffic type, and the actual payload. Expect to be overwhelmed if you haven't been here before. f)'other' - for everything not mentioned above, including malware scans with something other than Norton. >Any thoughts on what might be causing this problem? I'm still not sure what problem you're having. Every LAN has (nearly) constant activity.
