hi guys, im new in this forum seeking answer on how to solve a problem on our small office network, we are using win2000 server, all is well until one day, the NIC for the dsl connection is not accepting packets but the NIC for the internal network is fine, when i interchange their role, still the same, the NIC for the dsl is not working while the NIC for the internal network is fine, but when i disable the NIC of the internal network, then i can browse the internet from the server, do you know the solution? i have tried everything but in vain. thanks a lot for any advise!

if i were you i would have one NIC for both the dsl and internal network. i would take and hook my dsl connection up to a switch, hub, or router, and then assign ip addresses for each computer. and i would make the servers ip address the very first ip address on your network, such as 192.168.0.1 for example, and then make each computer have different network address that follows the server, such as 192.168.0.2 and so on. i would find out the ip address for your dsl connection and put it as your servers default gateway. and your default gateway to the internet for the other computers on your network would be your servers ip address, (192.168.0.1) only an example address). if you don't wanna do that, you could also make sure that the dhcp service is turned on on your other computers and that the routing and remote access service is turned on.

im sorry but to make it clear, i uses 2 NIC, one for the dsl connection (INternet sharing) which gets a dhcp ip address from the modem and the other NIC for the internal local area conenction whcih has a static ip address (192.168.0.1), when i interchange their role, the NIC connected to the dsl cannot get any packets,etc although when i check its ip address it gets a dhcp ip address from the dsl modem, what could be the problem? i think there is nothing wrong with the internal netwrok settings since its doing fine?

I'd go with the Wilson Family suggestion.

make sure each NIC is on a different subnet.

by now left tr

Win200 Server. Only one Default gateway can be used on the server. Should you need multiple routes use routing and remote access and turn the server into a router!

Have you accidentally turned on the options for load balancing or fault tolerance on the NIC's? If so they will act as one which is what it sounds like is happening.

In your setup you need the NIC's seperate but with IP fowarding enabled.

Also check any setting for IP packet filtering.
