Endpoint troubleshooting with evidence before action.

A Windows IT support engineering project for collecting endpoint evidence, isolating DNS/TCP/service faults, scoring incidents, documenting escalation, and validating troubleshooting workflows across a Windows environment.

Verified evidence

Windows endpoint verification.

The evidence below shows a completed Windows Server 2025 verification session for the endpoint triage and regression-testing workflow.

Operational design

Built around repeatable support work.

Collect first

System identity, disk pressure, DNS resolution, TCP reachability, Windows service state, and recent Event Log errors are captured before remediation.

Change safely

Network remediation is separated from diagnostics and supports PowerShell -WhatIf/ShouldProcess behavior.

Escalate with context

Runbooks and an escalation matrix emphasize timestamps, scope, exact failures, recent changes, actions attempted, and current workaround.

Troubleshooting history

Failures are kept visible.

The project history keeps the bugs I ran into during development and Windows verification, together with the fixes and retests.

Collector regression

While expanding the collector, I found bugs in disk threshold logic, DNS exception handling, and service-state normalization. I added regression coverage, fixed each root cause, and retested the collector.

Windows compatibility issue

A PowerShell interpolation error surfaced during Windows verification. The failing expression was isolated, corrected, and retested successfully.

Reporting pipeline

A Python evidence-template issue was identified during verification, corrected, and validated before the final documentation pass.
