Recently a few pc's in a small network often get disconnected from network applications and they cannot even browse the network resources. The network protocols are OK, we also changed the network switch and some UTP cables but it didn't help.
Is there a specific software to monitor such an inconvenience? Someone suggested Ethereal, but that's a sniffer, correct?! I mean, a specific software tool(either freeware or shareware) to retrieve corrupted packets and hardware errors.
