How to Activate Remote Desktop License Server (Web Browser Method)

Activate your offline server manually using a browser.

If your Windows Server does not have internet access or cannot reach Microsoft's servers directly, you can activate it by generating a license server ID and validating it via a web browser on another device.

⚠️ Requirement: You will need a second computer or smartphone with internet access to complete this process.

Step 1: Set Connection Method to Web Browser

  1. Open Server Manager > Tools > Remote Desktop Services > Remote Desktop Licensing Manager.
  2. Right-click your server name in the left tree and select Properties.
  3. Click the Connection Method tab.
  4. Change the dropdown menu to Web Browser.
  5. Click OK.

Step 2: Start the Activation Wizard

  1. Right-click your server name again and select Activate Server.
  2. Click Next on the welcome screen.
  3. You will see a screen displaying your Product ID.
    Leave this window open. You will need to copy this ID.

Step 3: Generate the License Server ID

Go to any computer or smartphone that has internet access.

  1. Visit the Microsoft Clearinghouse website: https://activate.microsoft.com
  2. Select the option: Activate a license server and click Next.
  3. Enter Required Information:
    • Product ID: Enter the Product ID displayed on your server in Step 2.
    • Company Information: Fill in your name and company details.
  4. Click Next.
  5. Confirm your entries and click Next again.
  6. Microsoft will now generate a License Server ID (a 35-character alphanumeric string).

Step 4: Complete Activation on Server

Return to your Windows Server.

  1. In the Activation Wizard, enter the License Server ID you just obtained from the website into the boxes provided.
  2. Click Next.
  3. The wizard should confirm: "You have successfully activated the license server."
  4. Important: If you are ready to install licenses now, verify that "Start Install Licenses Wizard now" is checked. Otherwise, uncheck it to finish later.
  5. Click Finish.

Verification: In the Licensing Manager, your server icon should change from a red "X" to a Green Checkmark, indicating it is now active and ready to issue licenses.
