KB: No RDS license when you connect to an RDS farm in Windows Server 2012

A new KB (2916846) was released by Microsoft in regards to installing the RDSH role (rol-based, not scenario based) and possible issues with successfully acquiring RDS CAL’s from a RD Licensing server.

“…Assume that you install the Remote Desktop Session Host (RDSH) role service on a computer that is running Windows Server 2012, and then configure the computer to obtain licenses from a Remote Desktop Services Licensing Server. When you try to connect to the computer by using Remote Desktop or Remote App, you may receive an error message that indicates there is no Remote Desktop Services Client Access License..”

“…This issue occurs because the RDSH server is missing certificates when a connection arrives and it cannot request a license for that connection to the Licensing server…”

KB: Best practices for setting up Remote Desktop Licensing across Active Directory Domains/Forests or Workgroup (2473823)

Microsoft has published a new KB article (KB2473823 ) covering Best Practices for Remote Desktop Licensing.

 

“…Question:
Can the RD Licensing (Terminal Server Licensing) server issue a Client Access License (CAL) to users or devices connecting to RD Session Host (Terminal Server) servers under any of the following conditions?

• RD Session Host servers are in an Active Directory Domain and RD Licensing server is in a workgroup environment
• RD Session Host servers are in a workgroup and the RD Licensing server in an Active Directory Domain
• RD Session Host servers and RD Licensing server are in different forests. No trusts exist (One-way or Two-way trust) between these forests
• RD Session Host servers and RD Licensing servers are in the same workgroup

Answer:
For both Per Device and Per User CALs issuance to work, the RD Session Host and RD Licensing server in any one of the following three configurations:

• Both in the same workgroup
• Both in the same domain
• Both in the trusted (Two-way trust) Active Directory Domains or Forest..”

RDS and TS CAL Interoperability Matrix

A few weeks ago Klaas Langhout created a TechNet Wiki on RDS and TS CALs. It answer a question that is often heard:

What CAL types can be used with what OS versions of Remote Desktop Licensing Server and Remote Desktop host server?

The Wiki provides a nice matrix that answers this question from Windows 2000 to Windows 2012.
