I have an environment that consists of a WIN2K3 Server at a hosted facility running AD etc... We have 4 offices with VPN tunnels to the WIN2K3 domain at the hosted facility. In each of the 4 offices I currently have FC4 boxes running as SAMBA PDCs each with their own domain. I wanted to be able to join all the XP Pro boxes in the 4 offices to the WIN2K3 domain and use Group Policy. The problem there is that many "important" functions of Group Policy don't work well over a WAN/slow link. Is it possible to use the FC4 SAMBA boxes as BDCs to the WIN2K3 domain and use replication so that Group Policy will work correctly? Any info on this would be very helpful, expecially where the smb.conf is concerned.
