This error frequently occurs due to packet loss, insufficient bandwidth, or slow VPN connections.
Try entering the remote computer's IP address (e.g., 192.168.1.50 ) instead of its hostname in the Remote Desktop Connection window.
Find the policy named .

If your system uses a Remote Desktop Gateway to bridge incoming external connections, forcing the client to utilize the RPC over HTTP protocol instead of UDP can bypass the 0x904 error entirely.
This step directly targets the "0x7" portion of the error and is effective when you suspect a security mismatch.
