Problem : The remote session was disconnected because of a decryption error at the server.
Simply put, we are getting “The remote session was disconnected because of a decryption error at the server.” when trying to remote into a Windows server 2k3 Enterprise SP2 box. RDP is enabled, I checked out the basics in the terminal services configuration, remote users are setup properly, and firewalls are off.
Solution: The remote session was disconnected because of a decryption error at the server.
