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
- Open Server Manager > Tools > Remote Desktop Services > Remote Desktop Licensing Manager.
- Right-click your server name in the left tree and select Properties.
- Click the Connection Method tab.
- Change the dropdown menu to Web Browser.
- Click OK.
Step 2: Start the Activation Wizard
- Right-click your server name again and select Activate Server.
- Click Next on the welcome screen.
- 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.
- Visit the Microsoft Clearinghouse website: https://activate.microsoft.com
- Select the option: Activate a license server and click Next.
- 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.
- Click Next.
- Confirm your entries and click Next again.
- Microsoft will now generate a License Server ID (a 35-character alphanumeric string).
Step 4: Complete Activation on Server
Return to your Windows Server.
- In the Activation Wizard, enter the License Server ID you just obtained from the website into the boxes provided.
- Click Next.
- The wizard should confirm: "You have successfully activated the license server."
- Important: If you are ready to install licenses now, verify that "Start Install Licenses Wizard now" is checked. Otherwise, uncheck it to finish later.
- 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.
