Hello!
As per https://technet.microsoft.com/en-us/library/cc785665%28v=ws.10%29.aspx
1) The order of policy application is: Local, Site, Domain, OU
2) "This order means that the local GPO is processed first, and GPOs that are linked to the organizational unit of which the computer or user is a direct member are processed last, which overwrites settings in the earlier GPOs if there are conflicts. (If there are no conflicts, then the earlier and later settings are merely aggregated.)"
It means if there're no settings in the site/domain/ou GPOs my local GPO settings must be the effective ones on a given computer. For example, I turn on Object Access in Local GPO while Default Domain Policy GPO has all Audit settings set to "Not defined":
...but the resulting policy is still "Not defined" (of course I do gpupdate /force). Why?
Thank you in advance,
Michael
