4780: The ACL was set on accounts which are members of administrators groups

On this page

This event, 4780, is logged whenever Windows modifies the ACL of a member of Domain Admins or Administrators to match the standard ACL in the AdminSDHolder object.  AdminSDHolder defines a stricter ACL to protect members of admin groups from being modified and taken over by other privileged users like Account Operators. 

Windows logs this event only for accounts where it actually has to change the ACL because of it being different from AdminSDHolder.  Typically you will only see it once, sometime after adding an account to Domain Admins or Administrators.

You will also see event ID 4738 informing you of the same information.

   Privileges:  -

Every hour, the Windows domain controller that holds the primary domain controller (PDC) Flexible Single Master Operation (FSMO) role compares the ACL on all security principal accounts (users, groups, and machine accounts) present for its domain in Active Directory and that are in administrative groups against the ACL on the AdminSDHolder object.  If the ACL on the principal account differs from the ACL on the AdminSDHolder object, then the ACL on the principal account is reset to match the ACL on the AdminSDHolder object and this event is generated
