HiI'm trying to create a collection, where the members is based on members of a AD security group, but i have some diffuculties getting this to work.any suggestions?

To get AD group membership for computers you can use either AD Security Group Discovery, or AD System Group Discovery. You'd use AD Security Group Discovery if you just want a collection that shows only the group name as members, no other members and no targeting for software distribution. You'd use AD System Group Discovery if you want to create a collection that contains each computer individually that is a member of the group, and you want to target software distribution to it.Then you can use Stefan's query as the membership rule.
