A Backup Domain Controller (BDC) can be connected to a remote domain
using Windows NT Server Remote Access Service (RAS). To promote a BDC that
is connected through RAS to a primary domain controller (PDC):

1. Configure the BDC as a Dial-out-only RAS client. The Remote Access Server
  service should not be running on this BDC. By having just the RAS client dial
  out services on this BDC, it can function as a PDC because that functionality
  does not depend on Netlogon.

2. If you promote the RAS-connected client, Netlogon stops, changes roles and
  restarts. RAS is dependent on Netlogon, so when Netlogon stops, the
  connection is lost.

3. A RAS-connected BDC that has been promoted to PDC functions as it should, but
  possibly with slower response time, depending on line speed.
