On more than one occasion, I've noticed that a machine will fail for patching.  After some investigation, the error message states "patch installed successively, but rolled back on reboot".  This doesn't happen for every system but it appears that it happens for certain Windows KB's that are included in the cumulative updates.

Does anyone know if this is true?  If so, how can I adjust to show that this isn't a failure?  Or at least so that it shows that the systems are patched.
