OK, so I tried what was advised below....to no avail...I
am running a firewall and telnet is disabled but the port
is still coming back as being open after running a
security check for open ports....I can't find anything in
the help area of windows that tells me how to do this the
right way.....it would make sense that the firewall would
enable me to close the port, but it's not there is no
selection in the internet connection firewall settings to
be able delete or close a port....am I overlooking
something or just an idiot????

Use CPanel: Admin Tools: Services to disable the Telnet
service.

IMO, you use a f/w to block (or stealth) an open or closed
port, and you
close a port by stopping the service that has opened the
port.

I disagree, but we're debating semantics. To me, closing
the port is
making it impossible for any application to use it. To do
that
requires a firewall. Apparently you use a different
definition.
Tim:
What do you call a port that is not open?
When you run netstat -an what do you call the ports that
are not listed?
I call them closed (you could call them "not open").
(note that the netstat cmd does not reflect the affect of
a firewall)
IMO:
A port is closed unless a service has requested that it be
opened.
The netstat -an cmd shows open/closed port status.
If you want to block (not accept packets, but respond) or
stealth (not
accept and not respond) a port you need a firewall.
By respond I mean: send an ICMP error packet or send a TCP
RST ACK packet.
You can have an open port and a firewall rule that only
blocks certain
addresses. The port will be available to all other
address. And the same
firewall rule would apply to a "not open" port (which I
call a closed port).
