[ActiveDir] Groups not replicating

[Malachi Burke]

Everything else seems to replicate fine.  Changes to existing groups and creation of new groups do not replicate.  I have some glitchiness in the DNS but it basically works (can resolve SERVER(s).domain okay).  Double checking that user creation replicates properly – modification of users replicates, as do DFS/FRS entities.  Event logs report happy successful times.  Any insight?   Malachi
