i have a customer with seven sites all connected by vpn links. there is only 1 dc at the moment , but they want to put one in 4 other offices. whats the quickest way to replicated the AD the first time, is there any way to do it rather than over the vpn link which might be slow

have the dc's located on the same subnet to begin with... replicate... move the dc's to the remote sites.  Then make sure you have the IP address ranges listed for each site in AD Sites and Services and then move the dc's to their own sites in AD sites and services.

If you have Windows 2003 domain controllers, your problem with slow VPN links can be resolved with "install from media feature": http://support.microsoft.com/kb/311078

No problems with IP address changes as you may not be running things like exchange on the remote DC's

does this sound like the way to do it

site - dublin
subnet -
ip address of server
sec dns (ip address of DC in other site)

site - cork
subnet -
ip address -
sec dns (ip address of dc in other site)

can i just do this for four sites or as many sites as i need assuming there is a wan link between them of course
