"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I removed the drivers from the classifications and the sync ran successfully. I have added them back in now and running it again to see what happens.WSCONTENT folder has new modified dates after the successful run, nothing yet, currently at 41% sync after adding drivers back, but it has failed at 80% before

When synchronization fails, status message ID 6703 is created by WSUS Synchronization Manager (the SMS_WSUS_SYNC_MANAGER component in Component Status) and log file entries are recorded on the site server. Status message ID 6703 contains different error messages depending on the problem that occurs.
