Scenario
Most office users reach the new internal site, but one subnet still resolves to the retired host.
Recommended Resolution Path
- Identify which DNS server the affected subnet is actually using.
- Check stale records, conditional forwarders, or local resolver overrides in that segment.
- Flush caches on a test endpoint after server-side cleanup.
- Update subnet-specific documentation so future cutovers include that resolver path.
Technician Notes
Confirm the result, document the root cause, and record any preventative action worth standardizing.
