DHCP lease updates fail after credential account lockout

Scenario

Scopes are healthy, but DNS registration and some lease tasks stop after the service credential account locks out.

Recommended Resolution Path

1. Review DHCP service account configuration and recent password changes.
2. Confirm event logs show the specific credential failure path.
3. Rotate the credential cleanly and verify dynamic updates resume.
4. Document the account dependency so future rotations include DHCP.

Technician Notes

Confirm the result, document the root cause, and record any preventative action worth standardizing.
