Assign Default Groups-Creating New User

Technically this should be referencing Active Directory in general..specifically on Win2k3 Server..

When I create a user I would like to assign them to 2 groups (in addition to Domain Users) by default without having to manually assign them. One group is a global distribution list and the other is a global security group. Each of these groups effectively mirror the Domain Users group. I need to synchronize user information into another application. The application has an interface that queries AD groups and pulls individual user information, however MS blocks pulling information from default user groups such as Domain Users,
