ERROR_IPSEC_MM_FILTER_PENDING_DELETION

ERROR_IPSEC_MM_FILTER_PENDING_DELETION (0x000032DA) The requested Main Mode filter has entered a deletion transition but has not been removed from all policy-engine references yet. Retrying create/delete operations immediately can produce confusing duplicate or not-found results.

Wait for the policy engine to release the filter and check which policy or active SA still references it. Recreating an identically named filter during cleanup can leave deployment state harder to reconcile.

What to check

  • Wait for policy reconciliation and verify the active rule set before submitting another change.
  • Check whether Group Policy refresh or a configuration-management agent is reapplying the same filter.
  • If the state persists, inspect the dependent policy and current Main Mode security associations before restarting services.
