I've never tried it but I believe that showmypc also supports restart.
As an aside, I once had a problem with a norton program which would crash on me, and some guy in India was busy on my comuter for over an hour (I think it was over 2 hours) and he kept working and restarting etc... (I left for Maariv in the middle! at the end he was not even able to figure out the problem). I think he use LMI.
