Start Network License Manager
To start MATLAB® software on a client computer, the network license manager must be running on the server. If you configured your operating system to start the network license manager when the computer starts up, the easiest way to start the network license manager is to restart the computer on which you installed the license manager.
There are several other ways to start the license manager, depending on your platform. This topic describes these methods.
The user name associated with the network license manager process should be a user that is defined locally on the computer, not defined on a network. The license manager starts up properly only if the user name can be found during the startup process on the computer, before network users are available.
Follow these recommendations when using the network license manager:

You can start the network license manager on Windows computers using any of the following methods:
Use the Windows Services control panel to start or stop the network license manager, if you chose to configure it as a service during installation. On the Windows Start menu, select Settings > Control Panel > Administrative Tools > Services.

Make sure that the network license manager starts at the very end of the system boot sequence. For the license manager to start correctly, the network must already be running. Use whatever mechanism your version of Linux provides to configure the boot sequence.
