I had a look at Samba and decided it was too much effort to set up. (I can be rather lazy) ;-)
However, someone did suggest that I try RC-FTPd, and I swear by it now.
It works fine here. On my LAN I have my 3000, my wife's 3000 and my stupid Win98 box. I use it to move files from my machine to my wife's or to the PC.
