Don't add another nic, It complicates matters beyond need.
Replace your existing server nic with a 10/100 nic, any one will do,
intel works nice, as do most of the $10 nics.
Go down to the computer store and find a SMALL (5port) 10/100 switch
(or hub). If lucky, you will find one with a cat5 port as well as a coax
port. Connect coax to it, and plug your server into one of the cat
5 ports, or any combination of that which works.
Remember, all you want this cheap hub/switch for is its coax port.
So if you can't find one, buy one without a coax port and offer it in
trade to anyone who has an older hub which almost always had
Since you will be buying a big switch to handle the whole house
anyway, make sure its 10/100 autosensing, and you can
plug any old 10meg hub into it to carry the load till you
Don't add another nic, its just more routeing problems than
