I have a major problem. We had two domain controllers. One was on a very old machine that would not be able to be upgraded from Win2000 Server to Windows 2008 Std Server. Performed a dcpromo to remove active directory and all went well, didn't get any errors.
On the other domain controller which was Windows Server 2003 Std, upgraded to Windows Server 2008. The upgrade appeared to be going smoothly and the progress bar appeared to have completed. After the final reboot, the machine will not boot, no error messages. Just a black screen with the words Microsoft Corporation on it and a constant scrolling green bar banner.
Does anyone have any suggestions? Exchange, which is hosted on another machine and is also not functioning. Probably due to the fact that there is no AD at the moment!!!
Thanks in advance for anyone's help!!!
