If these are corporate datacenters then what I have found is that they
typically have very complex firewall setups or QOS settings that can cause an
issue with these kinds of tasks. It may also be DNS related.
If we are talking 2003, I would reccomend doing an offline promotion with a
system state backup and then trying to replicate.
Install Active Directory from restored backup media
Updated: March 2, 2005
Use this procedure to install Active Directory from backup media to create
an additional domain controller in an existing domain.
Administrative credentials
To perform this procedure, you must be a member of the Domain Admins group
in the domain into which you are installing the additional domain controller.
To install Active Directory from restored backup media
1.
Click Start, click Run, type dcpromo /adv, and then press ENTER.
2.
In the Active Directory Installation Wizard, select Additional domain
controller for existing domain.
3.
Select From these restored backup files, and point to the same location
where you restored the system state data.
4.
If the domain controller whose system state backup you are using is a
global catalog server, the Active Directory Installation Wizard asks you
whether you want this server to also be a global catalog server.
5.
Give appropriate credentials for the operation.
6.
Enter the domain of the new domain controller. This domain must be the
domain of the domain controller whose system state backup you are using.
7.
Complete the remaining pages of the Active Directory Installation Wizard.
Dcpromo.exe will install Active Directory using the data present in the
restored files, which eliminates the need to replicate every object from a
partner domain controller. However, objects that were modified, added, or
deleted since the backup was taken must be replicated. If the backup was
recent, the amount of replication required will be considerably less than
that required for a regular Active Directory installation.
After the installation operation completes successfully and the computer is
restarted, the folder and subfolders that contain the restored system state
can be removed from the local disk.
