Initial replication can take a while when promoting a domain controller to an existing domain. This is especially true for domains containing a large number of Active Directory objects. In large-size enterprises we have seen the DCPromo process take upwards of two hours to complete even on fast network links. Not to mention remote/satellite/field sites with a slow WAN link. For such scenarios it may be valuable to perform DCPromo using Install From Media (IFM). Here is a quick how-to on performing a DCPromo using Install From Media (IFM). There are many posts on this out there, but this is a condensed version for quick reference.
