When i try enabling Windows SharePoint Services Help Search i get an error - SPSearch (administrator)

If you are horrified by the one line error message saying SPSearch (administrator), dont panic. All you have missed is specifying the domain for that user (whom you selected as the administrator). So instead of entering username in the configuration screen as "Administrator" try "\Administrator" (e.g., DEMOS\Administrator)

AS A RULE OF THUMB, WHEN YOU CONFIGURE SEARCH OR ANY SHARED SERVICES IN MOSS AND YOU ARE PROMPTED FOR USERNAME ALWAYS APPEND THE DOMAIN NAME IN FRONT OF THE USERNAME
