Installation for administrators

Stop and restart a network license server


To perform system maintenance on a licence server, including uninstalling Network Licence Manager, first stop the licence server. When you finish maintenance work, restart the licence server.

From a Windows licence server

Stop the server

  1. From the Start menu, search for LMTOOLS.

  2. In LMTOOLS, click the Service/Licence File tab.

  3. Select Configure Using Services.

  4. Select the service name for the licence server you want to stop manually.

  5. Click the Start/Stop/Reread tab.

  6. Stop the server. The best practise is to select Force Server Shutdown before clicking Stop Server. Then wait five seconds before attempting to start the server again.

Restart the server

On the Start/Stop/Reread tab in LMTOOLS, click Start Server.

From a macOS or Linux licence server

Stop the server

Enter the following in Terminal:

./lmutil lmdown -q -force

./lmutil lmdown -q -force

Restart the server

Enter the following in Terminal, replacing acad.lic with your licence file name and debug.log with your log file name:

./lmgrd -c acad.lic -l debug.log
