Does the switch automtically determine the network connection speed? We have upgraded our server to gigabit ethernet along with all our workstations, but still only getting 100mbps.
Also, all cables are Cat 5e.
Which model of switch are you using. Express 520 series has a max of two gigabit Ethernet ports. Make sure that your server is plugged into a gigabit port. Also make sure that your ports are either set for auto negotiation or hard coded for 1Gps.
