BitLocker network unlock not working after certificate renewal

Minimal guidance for messy support realities.

Scenario

Devices on the LAN should unlock automatically, but after certificate changes they still prompt at boot.

Recommended Resolution Path

  1. Verify the network unlock certificate and WDS or related infrastructure are current and trusted.
  2. Check whether the devices meet the firmware and network requirements for network unlock.
  3. Test one device on the expected subnet during a controlled reboot.
  4. Document certificate dependencies so future renewals include BitLocker services.

Technician Notes

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
