Probably a common error/problem encountered in Windows Vista, another one of those niggly problems that is enough to make users annoyed but yet not significant enough to change to another OS altogether…
Well, here’s the possible fix which worked for me on Windows Vista Ultimate SP1:
>>Right click “Computer”
>>Click “Manage”
>>Under the “System Tools” section, Double click “Local Users and Groups”
>>Click “Groups”
>>Right click “Administrators”
>>Click “Add to group…”
>>Click “Add”
>>Click “Advanced”
>>Click “Find Now”
>>Double click “Local Service”
>>Click “Ok”
>>”NT Authority\Local Service” should show up in the list now
>>Click “Ok”
>>Close Computer Management and reboot.

Hope this helps some Vista user(s) out there!
