Question

If the computer name of the Windows license server changes and no precautions are taken, then the name change will stop the license server. What to do when the name of your Windows license server changes?

This article answers the question and also helps to fix the problem when the name change happened and no precautions were taken.

Answer

If you plan to change change the name of the Windows license server computer, follow these steps:

  1. Change the name of the computer (this is typically executed by your IT department).
  2. Reboot the computer.
  3. Launch the License Server Adminstration (Start > Programs > Esko > System Controller > Tools > License Server Administration.
  4. Go to Handle license files, select Remove the Barco based License file and click Execute (this may take about one minute).
  5. Do the same for the Esko based license file.
  6. Reboot the computer.
  7. If you are on version 12 or newer, you can test whether it is solved by doing the following:
    1. Launch the Network License Manager.
    2. Press F4 and fill in the cusid.
  8. Change the name of the license server in all applications that are using its licenses.

If your client applications cannot allocate licenses anymore and it can be that the name of the license server has changed, you can follow the same steps.

To check that licenses do not work anymore because of a name change, you can do the following:

  1. Check the license server log file flexlm.log for errors.
  2. If you notice the errors "Not a valid server hostname...", this means that the computer name has changed.
  3. Now proceed with steps 3 to 8 as listed above. The problem should be fixed.
