I get this event on both DC's in my network every day at about 4 hr intervals.
I can't seem to find the cause. obviously there isnt an account named Nobody on the workstation that is making the failed network logon attempt. Port 3732 isnt a well known port. Can anyone help?
Thank You in advance.

According to the following Microsoft knowledgebase article, the SID S-1-0-0 means 'Nobody' which is interesting....

This could be a problem with the computer account on the domain.  Try removing the machine from the domain and then re-adding it; this could help.  Also make sure that the time service on the workstation is set to receive its time updates from your domain controller.  This can cause kerberos authentication issues.

The logon failure comes from different machines at different times of the day.  Time service is fine. and some of the machines have been removed and rejoined to the domain some haven't, Still the same issue. Added logon as a service to the quickbooksDB user, and logon failures stopped for that machine.
