IKE security association negotiation failed. Mode: %1 Filter: %2 Failure Point: %3 Failure Reason: %4

This audit is the primary diagnostic tool for determining IKE negotiation failures. It describes which mode (Main or Quick), which filter, where the failure occurred (Me or Peer), and gives an explanation of the failure as well as likely reasons for this failure.

Follow the suggestions in the failure string, if they are present. If trying to troubleshoot a connection failure using this, and the failure reason isn’t descriptive enough, search the log file (%windir%\oakley.log) for the description string in the audit. Make sure you match the filter and mode if you are on a machine doing many negotiations to make sure you are in the right spot in the log. Determine from the log where the failure occurred that generated this audit.
