I needed to run the MSINFO32 command recently, on a Windows Server 2003 machine, but it failed with an error stating:

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

Running services.msc showed the Help and Support service to be missing. This was resolved by launching the command prompt and navigating to the windows folder, then to the sub folder pchealth->helpctr->binaries and running the following command

helpsvc.exe /regserver /svchost netsvcs /rainstall

After running this command the Help and Support service re-appeared in Services and was already running and the msinfo32 command started successfully.

If you are still experiencing trouble I recently found there are some additional steps in this Microsoft article “Help and Support” feature is missing after you install Microsoft Windows Server 2003 SP2 on a computer that is running Windows Small Business Server 2003.
