Why not use ssh instead ?
That would be more secure than telnet and there also are free
Windows Clients available (putty for example).

Normally you can just disable all ports you don't need in your
/etc/inetd.conf.
If no entries are left, you can even disable inetd completely ^__^
But if you want to use some of these locally you could set up a
firewall, so only certain ports will be accessible from the outside.
(That's what I did on my machine)
