SBS2003 SP2 Help & Support

We've done a number of SBS2003 service pack 2 installs but not had this problem before, to fix the missing “Help and Support” service:

Help and Support Error
Windows cannot open Help and Support because a system service is not running.
To fix this problem, start the service named 'Help and Support'.

1. Start -> RUN, enter cmd
2. Change Directory:
cd %windir%\PCHealth\HelpCtr\Binaries
3. Run this command, it may take a minute or 2 to complete:
start /w helpsvc /svchost netsvcs /regserver /install
