Just open Notepad and type "command.com" without quotes
and save the file as batch.bat, and then you got cmd^^

- Net Send - Send Messages On Your Lan
 

i think that everyone who knows cmd knows about the "Net Send" function.
but if you dont know, its like this
 
just type Net Send * "Your Message Here" without qoutes
then it will send a message to all computers on your lan.
but it only works on windows 2000 and older.

- Net User - Make Yourself An Admin Account
 
the "Net User" function allows you to make accounts, also admin accounts.
but the problem is that, only an admin account can make new accounts.
so you will need to get access to an admin account.
the easy way to do that, is to wait until an admin forget to log off,
and then make an admin account
 
First use this code to make a new user:
Net User "Username" "Password" /add /domain
 
then use this code:
Net Localgroup Administrators "Username" /add /domain
 
If they dont use a domain, then you can take /domain away from the code.
