Connectivity Analyzer

The Connectivity Analyzer is a Windows-focused diagnostic tool designed to quickly validate connectivity from a device to Microsoft service endpoints such as Microsoft 365, Azure, and Windows Update. It executes a coordinated test suite including DNS resolution, IPv4/IPv6 reachability, ICMP ping, TLS handshake validation, and HTTP(S) availability. IT admins, helpdesk staff, and network engineers use it to reproduce user-reported outages, verify configuration changes, and confirm that required ports and protocols are open. Results are structured to support incident tickets and change reviews.
Conceptually the tool performs tests in stages: DNS resolution captures all returned IP addresses; reachability checks confirm path availability and record latency; TLS validation verifies that certificates are valid, trusted, and support current protocols; HTTP tests verify that service endpoints respond with acceptable status codes. Each test records metrics such as latency, status, and timing, and aggregates them into a concise report. Advanced users may adjust timeouts and enable parallel tests to simulate real-world paths behind proxies or VPNs.
The unique value lies in its focus on Microsoft service endpoints, deterministic results, and exportable reports suitable for helpdesk automation. Use cases include device onboarding validation, post-change verification, VPN or proxy troubleshooting, and SLA reporting. Benefits include faster issue isolation, consistent diagnostics across devices, and improved support documentation. The tool minimizes disruption by avoiding intrusive scanning while delivering actionable guidance.
