How Do I Grant Exception to the Network License Server in the Windows Firewall?

Primary Software: Electronics Workbench>>Multisim
Primary Software Version: 9.x
Primary Software Fixed Version: 9.x
Secondary Software: Electronics Workbench>>Ultiboard

Problem:

I installed the Network License Server (NLS) and I get message:

Connection to the license server failed.

I am advised to give exceptions to the NLS and to the TCP Port indicated in the NLS. How do I do that?



Solution:

When communicating to the NLS, any Firewall software installed in between the server computer and the client computer needs to grant an exception to the EWBNLSS application and the TCP Port indicated in the installation (default is: 1287).

The following instructions apply only for the Windows® Firewall in case it is activated. For other Firewall software please consult your vendor documentation.

Windows® Firewall instructions:

  1. Go to Start » Control Panel » Windows Firewall
  2. Switch to the Exceptions tab
  3. Click the Add Program... button
  4. Search for program name: Network License Server and click OK
  5. Now click the Add Port... button
  6. Give any name to the port configuration
  7. Type in the Port number you specified in the installation (Default is 1287)
  8. Select the TCP radio button and click OK
  9. Click OK to finish the Windows® Firewall configuration

Note: It might be possible that you need to restart your computer for changes to take effect, although is not usually required.
