First of all: telnet (server and client) are tools, available
for any operating system. Anyway,your question might
involve two layers (...if you now think of OSI, you are a
First, the telnet-server. Windows XP Pro comes with
a telnet service, which is set to manual or disabled
(depends on the SP). You can manually disable
This eliminates the standard telnet service, therefore there
Start -> Run -> services.msc
Go to "Telnet" -> Properties -> Disable
is no server listening on port 23.
Second, if a server of any kind (or most kind) is running on
your machine, the telnet-client can be used to connect to
it (you can "watch" web-pages using telnet, you can "send"
emails using telnet). If some kind of server is misconfigured,
telnet can be used to perform malicious actions - I think, this
is what you have read.
However, telnet is just one tool out of a many to do so. The
"solution" is to harden your box, ie patch the OS, patch the
applications, configure a firewall properly, disable services
which are not needed etc. There is a variety of tutorials
here on AO[2,3]

Run a netstat -ao from the command line and look for something that is :23. Get the PID for this process and it will tell you what is open on that port. If its not listed there, then its not listening.
