We have noticed that on some SBS 2003 installs the “Help and Support” service will disappear after installing Windows 2003 Service Pack 2. You may see the following error when opening "Help and Support" from the start menu:

---------------------------
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'.
---------------------------
OK
