 Server 2003 STD R2 to ENT R2 setup error
Windows Server 2003 Enterprise R2, Windows Server 2003 Standard R2
Trying to upgrade Windows Server 2003 Standard R2 to Windows Server 2003 enterprise R2 and get an error when I select upgrade. "Setup cannot continue because some necessary information cannot be accessed in the registry." "An I/O operation initiated by the registry failed unrecoverably. The registry could not read in, or write out, or flush, one of the files that contain the system's image of the registry" I login as the domain Admin ( this is a secondary domain controller ) and even tried copying all of the file to disk and install from their.
