MPSSVC Rule-Level Policy Change
Windows Firewall ignored a rule because its major version number is not recognized.
Firewall rules in Windows have version numbers embedded in them, and if they are processed on a version of Windows which does not support all features of that rule, the above message will be generated.
For example, if a rule is generated on Windows Server 2008 R2, and then deployed via Group Policy to a machine running Windows Vista, this event would be logged.
In most cases you should be able to ignore this error.
