I just tried using the latest installation of NoMachine (nomachine_5.1.62_1.exe) by installing it on both the server and client today.
I am still getting the same type of error messages. (The session negotiation failed. Error: Descriptor: FD#19136 not available)
Please advise if you were delayed on releasing the update before Christmas or if you weren’t able to solve the problem?
Thanks,
Dave
