Any suggestions would be > greatly appreciated. Telnetd and ftpd do a reverse name lookup. If the 3rd machines can't resolve your NT box'es address to a name, the same symptom will show up. If you can log into the 3rd machine, do `nslookup <NT-box-ip-address>' and see if it can resolve the address. If it can't, that is most likely your problem. You can fix it by either adding a PTR record to your named database or an entry in /etc/hosts and making sure /etc/host.conf says first check the hosts file.
