First off--- my current network arrangment:
INTERNET -> Cable Modem -> [NIC1] Server Computer [NIC2] -> Switch -> Workstations
|------------- Connection1 -------------| |----------- Connection2 -----------|
So basically, the server acts as the gateway between the network and the internet. That "Connection1" and "Connection2" part is what I see on the server's Network Connectons window. Just so you know... before the move, we just had the ISP's DSL-router in place of a Cable Modem; everything else was the same.
Which brings us to--- the problem:
Every single computer displays the message "Limited or no connectivity" - "You might not be able to access the Internet or some network resources. This problem occurred because the network did not assign a network address to the computer."
It's like there's nothing handling DHCP. And considering there's no router, that would make sense... but how's a basic network on a switch suppose to work then? It did before!
When I assign static IP addresses to everyone, it all works. But I have a laptop that I bring from work a lot (with its own VPN configuration), and I can't go changing network settings there. It must get an address automatically, which doesn't happen because it doesn't see a DHCP.
Any thoughts?
