Issue Details

I want to switch servers, but I don't want to change the settings in NI License Manager for every single PC currently connected to my license server. How can I get around this?
 

Solution

If you want to change existing servers and automate distributing the server change to all computers, there are several pathways available to make the change. 
  • You can modify or replace the contents of the servers.ini file found at  C:\ProgramData\National Instruments\License Manager\Data\servers.ini

    NI License Manager stores the license server information in a servers.ini using the following format:

    [Preferences]
    Order=port@ipaddress


    For multiple-server configurations, you may add additional servers separated by commas. In Windows versions prior to Vista, the server is located at the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\FLEXlm License Manager\NILM_LICENSE_FILE 

    Note:  Leave the path to the local license folder in this registry key if the client computer ever needs to run any activateable software from a local license.
   
  • From a networking perspective, you can set up a DNS address that points to the licensing server. As long as you update the DNS address to point to the new license server, you can move license servers without affecting client computers. 
     
If you are using Volume License Manager (VLM) and want to ensure new users are pointed to your licensing server, you can send them a Volume License Installer that will automatically configure their NI License Manager to point toward your server. Please see KB Creating Volume License Installer that Doesn't Send Permission Requests  for more information on using Volume License Installers to configure the licensing servers.
