windows 2000 server not installing updates

I manage a windows 2000 server, for some reason it has stopped installing WU's
The updates are downloaded but the install fails.
I have tried the senselogn key fix but that hasn't worked.
I have also tried deleting all the stuff under the software distribution
file but all thet seems to do is download the updates again the install still
fails.

Here is some of the windows update log
