Windows Update Agent Failures and Error

I run an SMS environment with some 3000+ machine in it and so get a
number of different failures and errors from windows update most of
these I have been able to resolve but the odd error sometimes comes up
the stumps me.

Currently I have 2 machines the will not run ITMU Scans. The error they
get in the WindowUpdate.log file is as follows.
