It might not look all that serious, but getting this when trying to boot into Directory Services Restore Mode is a bummer... Only solution I could find was to install a parallel copy of Windows 2003 SBS Server, then copy over the registry files from a good backup over the corrupt installation. And if your server have any kind of SAS RAID drive, Windows 2003 SBS Server will not recognise them, and will need the drivers in a floppy drive on A:. But as we all know that does not really exist anymore so... Slipstream your Windows 2003 SBS CD1...
