SYMPTOMS
Dcpromo may fail and you may receive following error messages in the \Debug\Dcpromo.log file:  08/02 07:05:22 [INFO] Validating user supplied options 08/02 07:05:22 [INFO] Error - An unknown error occurred while installing the Directory Service. (123) Error 123 translates to, &quot;The filename, directory name, or volume label syntax is incorrect.&quot;



CAUSE
This problem may occur if the site name that is specified or detected contains only numeric characters.



RESOLUTION
To resolve this problem, rename the site that is referenced in the Dcpromo.log file so that it is alpha-numeric. The site name can be found in a line that is similar to the following: 08/02 07:04:06 [INFO] Using site 202002 for server Abc.def



STATUS
Microsoft has confirmed that this is a problem in Microsoft Windows 2000.



MORE INFORMATION
Dcpromo performs its own DNS check against the site name to test that it is a valid label, but does not query DNS to see if the site name actually exists. A valid DNS label must contain at least one non-numeric character to distinguish it from an IP address.
