Hi,
the message comes from the Server 2003 basic code, which is not supported by the special means of Windows Home Server.
Would the OS start in Safe mode?
Does the message refer to a certain file? If the file name by bad luck is "SYSTEM", this means, the registry is damaged. In this case you need to use your WHS DVD to perform a Server Recovery. How this works, depends from the machine you have - is it a hardware
appliance from HP, Acer etc or some self built WHS system?
Best greetings from Germany
Olaf
