SBS 2008 Installation failure
Posted on 2011-02-17
During an OEM installation of SBS 2008 the installation failed with a message "DCPROMO failed, server was not promoted to a domain controller" the screen presenting the failure message indicated that the installation would need to be restarted and the original installation location reformatted. The SBS 2008 server was disconnected from the LAN after it started the installation and before the failure message was displayed. Does the SBS 2008 need to be connected to the LAN in order to promote itself to a domain controller?
