+Notes to self: 
+1)if the group member is a cluster computer object it will thrown an error, I wasnt able to find
+2) there are servers whose objects cannot be populated. The handlying for these objects are not yet implemented as well.
+3) script runs around 4-5 minutes for 1500 servers, not sure if better error handling helps in decreasing script duration.
