5027 The Windows Firewall Service was unable to retrieve the security policy from local storage
Written when the Windows Firewall Service could not retrieve the security policy from local storage. The service continues enforcing the current policy.
Overview
The subcategory is Audit Other System Events. It is generated when the firewall could not read the locally-stored policy. The service does not stop; it keeps the policy already in effect.
How it is triggered
- When policy retrieval fails due to corruption or inaccessibility of the policy store (registry, etc.).
Security review points
- A new policy cannot be read and the old one is kept, meaning the intended latest defensive settings may not be in effect. Also consider the slight possibility of policy-store corruption or read disruption due to tampering.
- Together with start failure 5030 and parse failure 5028, confirm the firewall configuration is correctly applied.
Notes for log review
- It is a rare fault event. When it occurs, check the health of the policy store and whether the currently enforced policy is as intended.
