FAQ

Are there additional actions I need to take after I have installed the update? No action is required from customers who are using a single license server and who are not using workgroup-joined Windows Server 2008 terminal servers. Customers using multiple license servers should refer to Use multiple remote desktop license servers for more information about the steps they need to take. Additionally, for proper license server discovery, customers using workgroup-joined Windows Server 2008 terminal servers will need to ensure that they list the RD license servers they want these terminal servers to use under Use the specified Remote Desktop license servers as detailed on this page. The License server discovery mode called "Automatically discover a license server" will no longer be supported in workgroup-joined deployment.
