Issue: When a user tries to connect to an RDP relay session through the user console, the session does not start. This may happen if the target server is unreachable.
Workaround: An administrator can perform the following:
Ensure that the Remote Desktop Connection is enabled in the System Properties of the target machine.
Ask the user to check if RDP Relay host is reachable by using the DNS name and IP address.
Ensure that the 13389 port is not blocked by firewall in the user’s computer.
Check if RDP relay from the Manager to the target server is working fine.
Check if the target server agent logs the error agent is not initialized. If this error exists then, restart the agent server (Windows restart).
Check if the target system agent logs the error user lookup failed. If this error exists, then ensure that the RunAs user is available in the target server.
Ensure that the Agent for Privileged Account Manager is installed on the target machine when the session capture is set to On. If the Agent is not installed on the target server, and the session capture is On, RDP relay fails, then you need to modify the policy by setting the session capture to Off.
