STATUS_CTX_TD_ERROR
The Terminal Services transport layer reported an error
This status is a boundary between Remote Desktop Services session management and the lower transport path. It does not say which packet or channel failed; it says the transport driver returned an error to the Terminal Services stack.
For modern RDP, investigate listener binding, TLS/security negotiation, gateway involvement, firewall policy, and connection reset evidence. For older deployments, the same family also covered non-TCP transports and modem-style connection paths.
What to inspect
- Record whether the failure happens before authentication, during graphics negotiation, or after session creation.
- Check TermService, Schannel, network and RD Gateway logs together.
- Compare direct RDP access with access through brokers or gateways.
