Chat with command prompt

When you're finished,
click on file, save as,
then save it as
messenger .bat.
Go to control panel
(make sure you are in
Classic View) . Click on
"administrative tools", then
click on "services".
Now find the
"messenger" service in
the list on the right,
then open it . You'll see
"startup type" which should
be disabled, so click on that
and select "manual".
Now press the start
button in the upper
right hand corner of the
window (not the green
start button), and click
apply .
Next, do the same
procedure on the
remote computer . Until
this service is activated on
that PC, you won't be able to
use this!
Now click on the
messenger file you
made . Since it is a batch file
it will open with cmd
(command prompt). It should
show "MESSANGER" at the
top and "User:" below that.
Type the IP address of the
remote computer. If it is in
the network, then when you
type the message next, it
should send it to them. It will
be likewise on the other
computer. There you have it!
