Strange issue with network in one class
Maybe someone can shed some light on our strange issue.
Today morning all computers in one classroom decided to be pinged. Can't ping them from any computers, including servers. Tried to fix it with cleaning dhcp and dns records - nothing.
They do appear on network search, but can't ping them. They do not appear on Lanschool either.
But if you login on those computers , they seem to be fine, no problems with browsing network and internet. Windows firewall is sett to allow pings through and everywhere else is fine, just this one classroom.
Teachers computer there is fine. Checked switches, all good.
Not sure where could lie the problem. Next thing to try, will rebuild one PC and see.
Thanks in advance
