If you cannot change settings on the host machine, try adjusting your client to match the server's requirements.
Remote Desktop Protocol (RDP) is a vital tool for IT professionals and remote workers, but it can be frustrating when a connection fails. One specific, challenging error is .
:
The error combination 0x904 (general connection failure) with extended code 0x7 (specifically pointing to an authentication protocol or state issue) often occurs when the client tries to connect using NLA, but the target computer rejects it or cannot process it due to a configuration drift. If you cannot change settings on the host
2. Reset the Crypto MachineKeys Folder (Azure Virtual Machines)
NLA is a security layer that requires users to authenticate before a session is established. If there’s a mismatch in security certificates, the connection will drop with error 0x7.
Windows generates a local cryptographic certificate to secure RDP sessions. If the server-side certificate becomes corrupt, expires, or suffers from broken private key permissions, the TLS tunnel cannot form. : The error combination 0x904 (general connection failure)
This specific error typically emerges on modern operating systems like Windows 11 and Windows Server 2019/2022. It surfaces right after you enter user credentials, causing the session to drop entirely.
This error typically indicates that the client cannot reach the remote host, often due to the remote computer being unreachable or the network path being blocked. This essay provides a comprehensive analysis of why this error occurs and offers a step-by-step guide to resolving it.
: Test the connection using the host's IP address rather than its DNS name to rule out name resolution issues. Use the command Test-NetConnection [IP] -Port 3389 in PowerShell to verify the port is open. If there’s a mismatch in security certificates, the
Ensure that the NETWORK SERVICE or SYSTEM accounts have permissions. Restart the Remote Desktop Services service. 3. Change RDP Transport Layer (RDGClientTransport)

Press , type certlm.msc , and press Enter to open the Local Computer Certificates manager. Navigate to Remote Desktop > Certificates .
