Has anyone ran a netstat from command prompt?
from command prompt type :- netstat -a

this will list the active tcp connections running on the machine at present so make sure you close all p2p apps, browsers, chat apps etc.
windows will usually have between 6-8 tcp connections, if you have 15+ run a full system check for virus and spyware on the pc.

2nd

from command prompt type :- netstat -b

this will tell you the executable file that is running the tcp connection from the machine if there are any you dont recognise google them and take action against any unwanted active tcp connections as ths can help a great deal when troubleshooting.

hope this helps guys
