If you just want all members of group A and group B to be in a dynamic DL, populate a custom attribute (1-15) on the groups, then define your Dynamic group using the Exchange console, to include Mail enabled groups that contain that custom attribute value. I just tested this in Exchange 2007 EMC. <br />
<br />
If you are looking for only a portion of group A and group B, Endital1097's solution looks good.

<br />
New group that im trying to create (Group G) needs to contain members of group A and B which are also members of group C<br />

Anyone have an idea on how to create a dynamic group with this kind of complexity
