When setting up XenDesktop 7.1 or higher, the licensing node displays the following error message, "Citrix License Server unavailable. Check the license server to make sure it is running."

Note: The Citrix License Administration Console has reached end of life and end of support in Citrix Licensing 11.16.3. Use the Citrix Licensing Manager

Verify the License Administration Console VPX software is version 11.12 as there are known issues that prevent the use of Desktop Studio from configuring the XenDesktop site to use License Administration Console VPX version 11.12 through PowerShell. 

The recommended way to correct this is to use a locally-installed license server first. (This can be uninstalled once XenDesktop has been reconfigured to use the VPX server.)

A windows based license server needs to be installed first to pass the initial site configuration page for configuring licensing.  Later you can point the Studio to a License Administration Console VPX Server.

Known Issue:

• When configuring XenDesktop 7.0, 7.1, and 7.5 or XenApp 7.5, use the PowerShell  Set-Configsite cmdlet to point to License Server VPX. 

• If doing a fresh install, install and configure XenDesktop and XenApp using the product installer within the software package, then use PowerShell to reconfigure and point to the License Server VPX.

​                               Set-ConfigSite -LicenseServerName <DNS_name/IP_of_licence_server> -LicenseServerPort <port>
