Too bad.

It's linked statically.  If you don't have tcp_wrappers installed,
you probably don't have the hosts.allow and hosts.deny files in /etc
and in that case, your problem isn't related to tcp_wrappers.

But *if* you installed tcp_wrappers *or* created these files by hand
on one of these machines, the rules given in these files apply.

Depending on the above, the rules are given in these files.  Note that
you connect using a normal ip address when connecting from w2k
(192.168.5.3) while you connect using localhost (127.0.0.1) when
connecting from nt4.  That's an interesting difference.

Other than that, you can always use strace and gdb to get more info...
