I have a bunch of PCs on a switch, and one can ping other PCs but they can't ping it.
It is not antivirus or firewall problems that is causing this as I have done a full format-reinstall and disabled the firewall.
I hooked up to a different network and it was fine, but not on this one. I changed the switchport it was plugged in to, changed the IP incase there was a conflict, have swapped cables, and have rebooted the switch.
Can anyone please help me this is driving me insane and causing major problems!!!
Edit: When I say ping I don't just mean pinging, I mean anything
