well ::ffff:192.168.0.93 is just an ipv6 representation of the ipv4
address 192.168.0.93 so I wouldn't think this matters but you could test
that by turning off ipv6 on the Fedora 9 system (there's no way to turn
on ipv6 on a Win98 system that I know of).

I wouldn't know about the DNS...do you run your own DNS servers? Are you
serving DNS for ipv6?

do you have restrictions in smb.conf that any of this would matter? i.e.
do you have 'hosts allow' or 'bind interfaces' type statements in
smb.conf?
