Why Does the System Display No Remote Desktop License Servers Available to Provide a License When I Log In to a Windows ECS?

Symptom

An error message is displayed indicating that there are no Remote Desktop License Servers available to provide a license and asks you to contact the administrator.

Figure 1 No Remote Desktop License Servers available to provide a license

Possible Causes

You have installed the Remote Desktop Session Host.

The grace period for Remote Desktop Services is 120 days. If you do not pay for it when the period expires, the service will stop. Windows allows a maximum of two users (including the local user) in remote desktop connections. To allow the access of more users, install the Remote Desktop Session Host and configure the desired number of authorized users. However, installing the Remote Desktop Session Host will automatically revoke the original two free connections. This leads to the preceding fault if desired number of authorized users has not been configured.
