In this article we outline the process for changing the license server manager port number.  This can be necessary if you are running multiple license managers on the same computer.  Port conflicts will prevent GeoStudio from acquiring a license.

Before You Start

• This process assumes the host operating system is Windows Server 2019.
• You should have direct administrator access to the computer the license manager is running on.
• You should have a list of available ports you can use.

Port range

• The default port range for a FlexNet License Server Manager is from 27000 to 27009.

Check for Ports in Use

1. On the 'Windows Taskbar', click on the 'Start' button (shortcut:  Windows logo key or Ctrl + Esc).
2. Open the 'Windows System' folder.
3. Click on 'Command Prompt'
4. Enter the following command to get a list of ports in use on the computer:
   netstat -an
   

Change the port number

The port number used in this example was chosen for illustration purposes only.

1. On the 'Windows Taskbar', click on the 'Start' button (shortcut:  Windows logo key or Ctrl + Esc).
2. Open the 'GEO-SLOPE' folder.
3. Click on 'FlexNet Publisher Dashboard'.
   
4. Click on the 'Administration' link at the top right corner.
   
5. The default user name and password are both:
   admin
6. If this is the first time logging into the Administration portal, you will be prompted to enter a new password. 
   • It is recommended that you record this new password somewhere safe. 
   • There is no method to reset the password other than uninstalling and reinstalling lmadmin.
7. Click on the 'Server Configuration' tab on the left.
   
8. Click on the 'License Server Configuration' section title.
   
9. In the section that specifies 'Use this Port', enter a new port number.  In this example, we will choose port 27100.
10. Once you change the port number, click on the 'Save' button at the lower right corner.
11. To ensure that the changes have taken place, restart the license manager service.  If you click on the Stop Server button at the top, the server will stop, but you will not be able to restart the service:
    
12. Instead, on the 'Windows Taskbar', click on the 'Start' button (shortcut:  Windows logo key or Ctrl + Esc).
13. Open the 'Windows Administrative Tools' folder.
14. Click on the 'Services' icon.
15. Look for the 'geoslope-lmadmin' service
16. Right-click on this service and choose the 'Restart' option.
    
17. The new port number is now in affect.

Configuring the GeoStudio Client

1. Start your GeoStudio client and choose the 'Help' | 'License Management' menu option.
2. Select 'Network Settings' from the pane on the left:
   
3. Ensure that the 'Enable network (floating) licenses' check box is checked.
4. If there are no license server entries, you will click on the 'Add' button to make one.  If there is an existing entry, you will click on the license server name and edit it.
5. In this example, the license server name is:
   license
   and the port number is:
   27100
6. Enter the port number, followed by the '@' symbol, followed by the license server name (it is only necessary to include the port number if it is outside the default range):
   
7. Now, click on the 'Test' button.  After testing that the connection is successful, click on 'Apply' and close the License Management window. 
8. Your network licenses are now available.
