accessing windows machines on my home network

[Anton]

Things seem to be hunky dory from the XP boot (accessing the other winME 
machine) so I'm pretty sure things are working ok. The card is 
recognised and seems to be installed properly. (Sorry, but I'm just 
starting...) What now? I would like to have the 'net connection from (xp 
+ mandrake9.1 on the box) linux so my wife can connect to the internet 
with her ME via me (sorry, that was bad :-). It's a std 10/100 to 10/100 
enet with UTP in between. Any suggestions on where to start? Easiest 
options first please!
Cheers
Anton
ps I would love to rid my home of ME, but the wife would skin me if I 
put Linux on her box... she isn't a devotee yet... :-)
