Audit policy between 3 domain controllers

Hello,

I have 3 domain controllers a part of one domain setup for syncronization.

I have a GPO setup to enforce audit policies so I can track user logons and such.

DC1 - audit policy is applied

DC2 - audit policy is applied

DC3 - all audit policies are not defined.

I am fairly new to AD and GPOs. Here is output of gpresults /v. Any help would be appreciated.

Thanks!
