The group name should be identical to the "Group name (pre-Windows 2000):" field when you look at the group properties in Active Directory Users and Computers. 

Within the top level node there are several other nodes (continents really) that have the same structure.  As long as this name is the same in DNN as it is in AD, they should sync and then I can allow only those users to log in, correct?  I want to make sure all the Sales Reps are included from all the nodes (continents) and not just one node.  I have a screen shot if you would like to see it but you would have to email me.

Ok after reviewing AD a bit here is what I find: (for simplicity I have not included some nodes)

• top level domain.net
  • Computers
  • CSG
    • Asia
    • Australia
    • Europe
    • USA
      • Canada
      • USA
        • Admin (not an object)
        • IT (not an object)
        • Sales (not an object)
        • XXX - Sales Management (has three heads for icon vs the folder with a phone book in it) Object?
        • XXX - Sales Internal (has three heads for icon vs the folder with a phone book in it) Object?
          • Sales Reps  (not an object)
          • Customer Service (not an object)

So I would assume the XXX-Sales Management is the object I am looking for to name the same in DNN as the others just appear to be folders with a phone book in it. 

Sorry for what would seem like simple questions.
