This happen in the LAN of a small company
I am responsible for IT with a colleague
Since a couple of months (nothing special changed since then), two PC gives erratic response to ping
I mean, figures like 1ms then 300, 100 200, 1 , 35 etc...
Both PC are cables to the same switch
When I unplug on cable an plug it into my laptop (same OS all, Windows 7), then I get 1ms forever, excellent.
What shell I check to find the "guilty" ?
