Currently we facing with the network issue at my office. My office has 2 floors (First floor and 2nd floor). Both floors able to access internet but currently all computers in the 2nd floor unable to ping each other in the same floor
(they can ping to all computer at first floor). Computer at first floor unable to ping any computer at floor 2. This issue never happen before and all computers are working perfectly until this morning. Now they unable to print to any sharing printer due to this issue.
-We already disable the Firewalls and allow incoming echo request.
-We already ipconfig/flushdns , ipconfig/release, ipconfig/renew and netsh winsock reset.
-All computers are connected to one main network switch.
-We using dynamic IP for all computers and confirm that they within the same subnet mask.
-We are within the same domain (labgistics.com).
-All PC are using Windows XP.
-We are able to ping Gateway IP address from all computer at 2nd floor.
-We unable to find any computers listed at Microsoft Windows Network at any computers in the 2nd floor.
