My search is as follows:
(EventCode=4728 OR EventCode=4732 OR EventCode=4756) a_* (Group_Name= OR Group_Name= OR Group_Name=Group_Name3>
This search works well to identify when any admin account has been added to these groups. I want to know if I can extend this search to identify when 1 admin has been added to more than 1 of these groups. Any help would be appreciated.
