There are several items below to consider when configuring your server settings, as outlined below. If you encounter any issues communicating with your volume license server upon its configuration, please review the VLM Troubleshooting Guide.
After installing your license file into NI Volume License Manager for the first time, you will be prompted with a window to configure your server preferences, as shown below.
Configuring Basic Volume License Server Preferences:
Here, you can add your contact information to the server. This information will be displayed in the client version of NI License Manager, allowing end users to contact you if needed. This is also where you configure the port numbers, including the Communication Port and the Main Licensing Port.
Note: Unless you have a specific reason to change them, we recommend leaving the default port numbers as shown below. The Main Licensing Port is used by end users to connect to and communicate with the license server.

Configuring Email Preferences:
You can configure Volume License Manager (VLM) to use an email address to distribute information such as feature updates, notifications, and other communications:

VLM Preferences:
From the Volume License Manager home page, click Tools » Preferences to open the Preferences window. You can modify the settings shown above as needed, as well as configure additional VLM preferences such as enabling notifications, activating the overdraft feature, configuring custom data fields for storing information, and more.
