ethernet conflict??

Yetserday i set my red hat 9 box up so that it was connected to my home network, sharing a the internet connection off of a wondows xp machine. All worked fine. However the plan is to make the red hat box the internet gateway. To this end i have just purchased another Lynxsys NIC (the same as the one that is already in the machine). I set the card up in Windows XP, as the machine is a dual boot, and managed to share the internet connection across the network . I then tried booting RH. On boot RH recognised the new card, eth1 and did the dhcp auto set up connecting me to my ISP, however eth0 (the connection to the rest of the network that worked yesterday) failed. I have tried deleting it and reconfiguring it using the GUI but to no avail. I just get the message that "RedHat-Config-Network: Can not activate network device eth0"

I know it is not a problem with the card not liking Linux as it worked yesterday. I also know that i have not damaged it since yesterday, while putting the new NIC in, as it works in Windows.

I am kinda stuck for ideas.

Any help greatly appreciated.

Cheers in advance,

I have manually entered the IP address and Subnet mask and now eth0 fires up. However when i attempt to ping another computer on the network it does not work. If i try to ping the red hat box from another machine on the network then i just get a request timed out message.

A friend has told me that this could be an IRQ conflict as apparently Windows and Linux handle them differently. Is this true and if so how could i rectify the situation.

Edit: I have looked at the red hat guide and it says to add a one line aliase but i am not sure what this means.
