Hi, I apologize for my english. We have a Windows2012R2 Terminal Server Farm.
The farm have: 5 RDHost Servers, 1 RDLicensing Server, 1 RDGateway Server. They are configure with RDConection broker (High Availavility Mode). The users use RDwebAccess to login to terminal services and use rdwebapp. Since few mounth some usrs have reported that they can not access to terminal server at the first try. They recieve a Protocol Error (ProtocolError.png) four time or more until they finally can connect. Sometimes, after the first Protocol Error, they receive another message that indicate the remote desktop services is currently busy (RemotedesktopBusy.png). Usually after several attempts, they can connect. Our users use Windows 10 Pro, and Windows 7 Pro. The error appear independently of the Client Windows Version and independently of the application that they try to open. Sometimes i proved changing the username and the connection was successful. But when tried with the original user the error comes back.
I used the remotedesktop diag tool and nothing seems to be wrong configured. I will appreciate if someone could help us.
