I have a 3 Com 2226 switch in another building. It is connected by fiber. I can ping the switch its self from the building that I am in, but I cannot ping devices on the other side of the switch in the other building. From the devices in the other building on the other side of the switch I can ping devises in this building. Other communication including VOIP phones are working fine. I have looked in the Web interface of the 2226, but have on found anything that would prevent a ping.
Antivirus is running on the computers that I cannot ping, but those computers have the same settings in the Antivirus software as computers in this building that I can ping.

i suppose you have different vlan configured for management
can do provide me with the information:
what vlans are configured between two 3coms?
what ip subnet you are using for pcs in both buildings and what ips you have for your switches.

ok, and what about mask for the subnet on your network and for the subnet on the switch?
possibly in some places you have 255.255.255.0 and in some 255.255.0.0

No, the only firewall on the PC's is Windows and it is off.

I have replaced the switch and still have the same problem. It has to be a firewall or antivirus issue.
