    I currently have a server based at a datacenter running web services, email
    etc... It's a domain controller also.

    I'm in the process of trying to migrate all the data to a new server at a
    different facility but am having trouble.

    I"m trying to make the new server a domain controller for the domain, then
    demote the existing server so i can then start to get the rest of the data
    off it so it can be decomissioned.

    However, when I try to dcpromo the new server, I get "rpc server
    unavailable" - anyone else tried to do a similar thing before? Any ideas how
    to get around it?

    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
    Click Start, click Run, type dcpromo /adv, and then press ENTER.

    In the Active Directory Installation Wizard, select Additional domain
    controller for existing domain.

    Select From these restored backup files, and point to the same location
    where you restored the system state data.

    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.

    Give appropriate credentials for the operation.

    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.

    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.
