Hi Daren,

Sounds more as a service or scheduled task that's trying to do something
with bad credentials. Check if there're scheduled task at 13:30. Check also
if you have any service that starts with specific user credentials rather
than with system account.
You can also take a look what process is the one indicated by Caller Process
ID (but you need to do at 13:33, or you'll get a bad indication). You can
monitor process creation/deletion with PMon
(http://www.sysinternals.com/ntw2k/freeware/pmon.shtml)

Hope this will be useful.

Massimo.
