Hi @Aliki
since some week´s we have a strange error and no one can told me a sollution. So i will ask here ;-)
I have Clients, Win 7 and Win 10 which losses randomly Network Connectivty. The LAN- Icon at the Client show the yellow exclamation mark. No communication can be done. Switch 2960x show no log the port is all the time up. Wireshark show no error, broadcaststrom an so on ...
It seems that the client will have an IP- Adresse DNS- Server and so on but can not resolve the names ...
Did anyone hear about that problem.
