Step 3: Preparing to Deploy
Keeping that in mind, we will open up Run on one of the computers. You can do this by either hitting both the Windows key (the key with the Windows logo on it) and the "R" key, or by going under "Accessories" in "All Programs" in the Start Menu. When the Run bar comes up, type in "services.msc". (Of course, without the quotation marks.) Hit enter. A new menu should come up with a list. The list is in alphabetical order, making navigation easy. Find where it says "Messenger". Right click it and select "Properties". Where it says "Startup Type", put "Automatic". Exit out.
Repeat this for all the computers. You'll get fast at it with practice.
To check if a computer already has net send enabled, open the Command Prompt. It can be opened either by typing "cmd" into Run, or by clicking on it in "Accessories". Now type "net send /?" (again, without the quotation marks). If it responds with information about the command, then it is already enabled. If it responds by saying that "net send is not a command", than net send is not yet enabled.
