Hi every one !

I'm experiencing a little pb under winXP pro : i've set up a three-computer switched network.
All the comps run under the same os.
Everything's ok : internet connection sharing, file and printer sharing works very well.
But 2 of the 3 computers are constantly exchanging data... even when no program is currently running. (the leds of the switch are constantly blinking)
I installed a packet sniffer and i found that they were sending data aver ports 1069 and 2869 (tcp).Theses ports seem to correspond to icslap and cognex insight.

Does anyone have an idea on what it can be ?
