6 person office with Windows Server 2008.
Netgear N300 wireless router with a 4 port switch attached to one of the ethernet ports on the router.
Server is currently plugged into a port on the router.
Any user plugged into the router can access server and internet.
Any user plugged into the switch CANNOT access the server or internet, or ping devices plugged into the router for that matter.
I have replaced the router, the switch, and the cable between the router and the switch. I have changed the cable from the server to the router.
I'm scanning the server right now for viruses. The server can access the internet, and users plugged into the router have no problem, so I think no problem with the server NIC, but replacing it would be my next step.
Any ideas appreciated!
