ping self ok --> IP stack working properly and has layer1 connectivity


ping local subnet no response --> maybe firwall block it. Check ARP table of

the PC that issue ping command to make sure your switch can resolute the right

MAC of that host. No matter firewall block the ICMP(ping) or not, ARP must

always works fine in the same subnet.

If you don't have correct ARP table on your PC, use ARP -d command to

clear ARP table then try again. It is faster than reboot it.


"Network Neighborhood" problem is mostly like name resolution issue.

Make sure you can ping the IP of the host before you connect to its folder.

If you can ping the IP of the PC but have no access to it, probably you don't

have NetBIOS running or name resolution is not working. Edit the LMHOSTS

file or have WINS server running is an extra insurance.

Good Luck!
