Hello,
Thank you for posting on the Microsoft Community forums.
First, ensure that the network configurations on your RDS device are properly set up.
Additionally, verify that the Remote Procedure Call (RPC) service is operational on both involved servers. This can be accomplished by opening the Services console and locating the service named "Remote Procedure Call (RPC)".
For software compatibility concerns, consult the support teams of the software applications in use to ascertain whether they are compatible with the version of the RDP device you're currently employing.
Regards,
Jacen Wang.
