First thing that you want to do is make sure that your server service is in fact running.
To access a configurable list of services, open the Start menu and click the 'run' command.
In the text box, type: services.msc and hit ENTER. This will bring up the services management window. Scroll down until you see the one titled "Server". When you find it, double click it and make sure that it is set to automatic in start up type, and then make sure that it set to started. If not, after you apply the change (if needed) to start up type, click start to start the service.
This will set it to start every time the computer is restarted if it wasn't before. You need to do this will all of your networked computers.
