Apparently there is a bug in Netatalk that makes VM shared folders behave all wonky, they don't recommend sharing VM shared folders... That would explain why it wouldn't mount correctly. So, that option is out if I'm going to run it in a VM. Other users trying to set up something similar have all reported the same bug!

I'm going to try Windows Server 2000 as a VM instead of NT, so I can try out Services for Macintosh. It only needs 256MB of RAM which is what I was using anyways, so that works for me. I'll also check out PCMacLan, thanks for the recommendation. :>
