How to Setup Terminal Client Access License (CAL) in Windows Server?

By default, two users can connect to Remote Windows server via Remote Desktop. In certain situations, you are required more than 2 users to connect and work simultaneously on the same server. For example, your server administrator team is working on your Remote Windows server and at the same time your developer team wants to access the server. That's when Remote Desktop CAL comes into the picture. RDP CALs enable the users to establish more than 2 Remote Desktop sessions on the same Windows server.

At AccuWebHosting, we offer RDP CAL license at a cost of $25/month for additional 5 Remote Desktop users. To avail additional CALs, you just need to submit the support ticket from your Helpdesk.

  2. Ciick on Start button then right click on Computer and select Manage option. This will launch Server Manager window.

Activate the CAL license

If you noticed in step #8 (Licensing Mode stage), we selected the Configure Later option that means CAL license is yet to activate. If you do not activate the license within a certain time frame, then Remote Desktop services will be stopped automatically. In order to activate the CAL license, AccuWebHosting customers can submit the ticket from client area. If you are not AccuWebHosting customer, then you'll need to contact your license provider.

Add RDP users to verify multiple Remote Desktop sessions

So far you've successfully installed the Remote Desktop role and activated the CAL license. Now, it's time to verify that you are able to establish more than 2 Remote Desktop sessions.

We deliever Windows VPS with two default Remote Desktop users i.e., Administrator and AccuWebHosting_tech/Tech_support. To verify multiple remote desktop sessions (more than 2), you'll need to create one more Remote Desktop user and try to connect to your server using all three users at the same time. If you could connect with all three users concurrently then you've successfully installed the Remote Desktop services.
