How to unsync drive (or how to get mobsync to not run)

I recently had to reconfigure my server computer, and this required me to
delete my drive mappings to the server drives on my main computer. After
the server was up and running, and I went to map the C: drive on the server
as the X: drive on my main computer. Somehow (although I didn't make this
choice), it selected "Always Available Offline" for the entire drive. So,
the sync center (mobsync) now runs automatically when I start my computer,
and attempts to sync that drive. I've searched and there is apparently no
way to stop mobsync from running (not even msconfig will do it). The
solution apparently is to go to each folder on the "shared" drive and
unselect "Always Available Offline". Of course, this is a real pain, but
I've managed to do it for all of the folders on the drive except for 2,
Program Files and Windows. These folders simply give me an "Access Denied"
response, and there is no "Always Available Offline" selection. As far as I
can tell, there is no way to give my computer the appropriate permissions to
access these folders over the network.

So, I'm in a Catch-22. How do I unsync these folders?
