I have Cisco 3560 as VTP domain and Cisco 2960 as VTP client. I am facing a strange issue on my network. Somtime I am unable to ping a server from particular one workstation and some time not from any or some workstattions. From Cisco switch itself when I try to ping I get only one reply then no reply. I have changed the server's lan card, lan cable, switch port, remove antivirus, disabled firewall and even reformated the server's os. But issue is still there there and it happens intermittent to many servers. Kindly help how to resolve the same.
