Windows endpoint readiness
A read-only support utility that separates DNS-only faults from broader network-path failures and leaves an escalation-ready evidence bundle.
Validated result
Two controlled Windows faults were reproduced, classified, corrected, retested, and rolled back in fresh disposable sessions.- Windows 11 Pro ARM64

01 · The support question
What needed to be known?
A user can report “the network is down” when the adapter, route, DNS resolver, or one service is actually at fault. The project needed to narrow that ticket without changing the endpoint.
02 · The build
A controlled path from fault to retest.
- 01
Collected adapter, address, route, DNS, ICMP, and TCP evidence through a bounded PowerShell module.
- 02
Classified incomplete evidence as unknown instead of treating missing data as proof.
- 03
Injected a DNS-only failure and a wrong-static-network failure outside the read-only collector.
- 04
Repeated the same checks after correction and again after fresh-session rollback.
03 · What proves it
Evidence tied to the claim.
DNS-only fault
IP and TCP remained available while name resolution failed; the collector returned Fail / DNSOnly.
Wrong static network
Address and route evidence changed together; the collector returned Fail / NetworkPath.
Release gate
The public payload was rebuilt byte-for-byte, checksum-bound, sanitized, and independently reviewed.
