STATUS_CTX_PD_NOT_FOUND

The configured protocol driver was not found

This status indicates a missing server-side connection-stack component. The listener is configured to use a protocol driver, but the service cannot locate the module or registration required to load it.

Because it occurs at the Terminal Services layer, changing an application setting inside the session will not repair it. The repair path is component installation, role repair, service configuration, or rollback of the change that removed the driver.

What to inspect

Compare the configured listener with installed Remote Desktop Services components.
Check file-system and registry state after updates or security cleanup.
Confirm whether only one listener fails or the entire Remote Desktop service fails to initialize.
