Fail over to another node

This issue can happen if the Remote Desktop Connection Broker service is manually restarted on the active node. To resolve this issue, you must fail over to another node by using Failover Cluster Management.

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.
