My business has 4 computers (2 desktop, 2 laptop)all running vista and all connected through Ethernet cables. All 4 were working fine, then all of a sudden, the 2 laptops cannot identify (access) the LAN. The desktops are still doing just fine. When connecting to the same cable as the desktop, the laptops still do not work. On the network and sharing page from the control panel, the laptops both show that if cannot identify the LAN and keeps looking for it. If this problem is familiar with anyone, I would appreciate any suggestions. Thank you, Tim
