This is the setup: Each computer (one acting as a server with Win 2K3 server and the others clients with Win XP) in the network has got two (2) network cards installed. Card #1 ('Internet') on each computer is set up according to the ISP's instructions; dynamic IP address and DNS , and is connected to a router (D-Link DI 704).
The Card #2 ('Homenet') is on each computer set up with static IP address (192.168.0.1 for the server, 192.168.0.2, etc.) and DNS (192.168.0.1) as well as netmask (255.255.255.0) and they are cabled to a hub.
This is the wanted outcome: To be able to surf the net also if the server is turned off (or worked on or malfunctioneing or for whatever reason is not in use) and be able to run an efficient internal network (when the server is working OK). Also, it is wanted to be able to run the computers with the two cards activated all the time.
This is presently causing a problem. If the server is running, and Card #1as well as Card #2 on client computers are activated, surfing with the client computers is not possible. With other words, if the server is running and both cards are activated, card #2 'takes over'. If card #2 is inactivated on the server, surfing goes smoothly on clients also if card #2 is activated. Also, if card #2 is inactivated on a client, but activated on the server, surfing is OK.
How can this problem be solved?
