We have a group of XP machines which have not been getting their Windows Updates even
though I've specified it in the ZEN workstation policy. This policy is applied to
all of our campus XP computers, and since it seems to work in most places I can't
figure out why these machines are having a problem.

The policy specifies to automatically download and install updates. However, some of
these systems are configured to download but wait for administrator approval to
install. The weirdest part is that some of them seem to be switching back and forth
between these two settings. As I was working on one yesterday that was set for admin
approval, I noticed that it had changed to automatic installation. I have no idea
why, but I suspect it's a policy issue.

Below are some lines pulled from the windowsupdate.log file on one the machines. It
shows the Windows auto update mode switching back and forth, and most of the time it
is not "scheduled" like it should be.

I've checked everything I know of. How does one troubleshoot this kind of thing?
Thanks for any assistance.
