Windows Remote Desktop Connection Doctor

Diagnose and fix Windows App (AVD/WVD/W365) connection quality issues on macOS, with focus on transport protocol optimization.

Methodology base: the general evidence-driven diagnosis discipline lives in the debugging-network-issues skill. This skill is the Windows-App / AVD transport domain layer — it leans toward connection-quality optimization more than root-cause falsification, so the methodology overlap is lighter.

Background

Azure Virtual Desktop transport priority: UDP Shortpath > TCP > WebSocket. UDP Shortpath provides the best experience (lowest latency, supports UDP Multicast). When it fails, the client falls back to WebSocket over TCP 443 through the gateway, adding significant latency overhead.

Diagnostic Workflow

Step 1: Collect Connection Info

Ask the user to provide the Connection Info from Windows App (click the signal icon in the toolbar). Key fields to extract:
