I have opened telnet through the windows firewall. Port 23 is now open. When
I try to scan the computer it says port 23 is closed. Do I need a telnet
server? I want to test remote access through command line. Thanks for the help

Yes. Look under Services.

When you say you want to test remote access, do you want this machine to
connect *to* other machines? Or do you want to connect to this machine,
*from* other machines?

To telnet to another box from this machine, all you need is the telnet
CLIENT (telnet.exe). This is installed in Windows XP by default.

To telnet into this machine from another box, you would need to start
the telnet SERVER service. By default this is disabled in the Services
MMC, under Administrative Tools. Set it to manual or Automatic as desired.

You say that when you scan the machine, port 23 is closed. But you don't
say what tool you used to scan the machine, or what message the tool
reported. So it is pretty hard to comment on that.

An easy way to see if any thing is listening on port 23 is to run
'netstat -ano' from a command line. Assuming no telnet server is active
on the local machine, nothing should be listed as listening on port 23.
This is not the same as being actively blocked by the firewall, but it's
a good start.

Telnet can be useful, but obviously Remote Desktop is teh easier way to
perform administrative tasks remotely (esp for GUI-based tools).

Hope this helps

Andrew
