ERROR_IPSEC_IKE_NOTCBPRIV

ERROR_IPSEC_IKE_NOTCBPRIV (0x0000361B) The IKE service failed while trying to enable a required operating-system privilege. This is a local service or security-policy condition, not a peer negotiation mismatch.

What to check

Check the IKE and AuthIP IPsec Keying Modules service startup status and the System event log for the first related failure.
Review recent hardening, service-account, or local-security-policy changes that may have affected built-in service privileges.
Do not manually grant privileges to arbitrary accounts; restore the supported service configuration or use normal OS repair procedures if system components are damaged.
