I have 4 home computers, 2 running XP and 2 running Vista.   The question is with the 2 Vista machines.  I noticed that when I start these machines with network connections the number of received packets goes quickly to several million received and then sends several hundred thousand.  I have ran several SCANS and nothing appears wrong.  Is this number of packets normal on the Vista systems?  My XP units don't even COME close to that level of traffic. 

Maybe the two Vista machines are fighting for dominance over the network...

If you're INTERESTED, run Wireshark to find out exactly what they're talking about.  Might be worth switching your router off and seeing if the rate of traffic increases or decreases.

Note that this traffic might be Windows updates silently downloading in the background.The question for me is, are my machines acting as servers for some spam operation with that MANY packets flying around?  Quote from: Rob Pomeroy on June 01, 2009, 08:04:21 AM
