Erratic ping response time
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" ?

Additional info : as can be seen in the trace above, the first pings (5 to 15) are (always) excellent then the degradation occurs.
If I restart a new ping sequence just after another one, then it is degraded directly

Sounds like bad switch
You said if you move to a different area ...is that a different switch?

Same switch used everywhere
Can the problem be related to speed ?
Switch is gigabits, cards not
What is strange is that the problem was not there before
Users do not remember when the problem appeared, but it may be when we replaced the switch, in decembr 2015

First I would look at is updating the NICK drivers for the problem PC's
I take it that 192.168.1.5 is a "server" of some sort?
What happens if you ping an outside ip, like Google?

Yes, internal server
Will try pinging outside ...

Pinging outside gives excellent results ...

Either the server is busy as h*ck, something on your network is chewing up traffic, that user has an infection, or the switch(es) are having issues. Because switches are semi intelligent, I'd suggest cycling their power so they rebuild their internal ip tables. After that, current ports ( http://www.nirsoft.net/utils/cports.html ) can be very useful to reveal processes that should not be running which should be run on both the server and the affected workstation(s). Pingplotter free is also a visual traceroute which I would point at the server to reveal packet loss (PL%); though, I'd only go for replacement after repowering the switches. https://www.pingplotter.com/freeware.html
ASKER
Not a problem of infection I think as several PCs are concerned.
Will try what you suggest

NIC card upgrade is the solution !
Thanks

Same problem on a third PC, located in the same area
I moved one of these guilty PC in another area where equivalent PC (same box, same OS) are connected to the LAN and where the ping is OK.
For the guilty PC, the problem is still there
