How to Configure your Network License Server


You are setting up your network license and need to configure your server(s) so that it can begin issuing your Autodesk licenses.


After you've planned your network installed the Network License Manager (NLM) and obtained your network license file, you then need to configure your license server(s) in order to begin issuing your Autodesk licenses.

Configuring your license server consists of the following four tasks:

  1. Create a Debug Log File
  2. Configure the License Server
  3. Start the License Server
  4. Confirm the License Server is running

Create a Debug Log File

Debug Log files will contain information about how the NLM is running and is the first place you will want to check if there are problems getting a license or any other problems with your license server(s).

To create a debug log file:

  1. Create a new folder called "Logs", where you will save your log files.  It is recommended to save this folder to the C:\Program Files\Autodesk Network License Manager folder.

  1. Create a log file by opening up a new text file and changing the extension from “.txt” to “.log”.  You can name the file anything you want; however, it must end in “.log”.

    Note: We recommend including “Autodesk” somewhere in the title.

  2. The enquiry may take a few seconds and will display several pieces of information in the status window.  Scroll down to check for the following two lines of information:
  • YourServerName : license server UP (MASTER) v11.9 – this line tells you that the license server is up and running and that it is running the latest version.
