I connect to the Internet through a SMC modem/router that has 4 Ethernet ports. I have a network with a domain controller (windows 200 server) and five PCs. Three of the PCs conect via a hub.The server and the two other PCs are connect to the router.
port 1 - Server port 2 - PC port 3 - HUB - 3 PCs port 4 - PC*
After the weekend the one PC will not get an IP address from the network unless I disconnect from the router and go directly into the hub with the same cable, then all is OK.
The router was replaced and the exact same problem exists. HELP Gary
