I found the service that was causing the event. I started reststarting
non-essential services one by one until I found the service that was
generating the security event. I turned out to be a service from Adaptec. The
server has an Adaptec RAID card. I installed Adpatecs RAID management utility
on the server also. It is a browser base utility to manage your RAID. It
installs 3 services, one named "Adaptec Storage Manager Notifier" was set to
logon on as local service and would generate the event everytime I restarted
it. Why it was trying to use an account called "Secret" i have no idea, but
it sure was a suspicous name. Well I don't believe it's anything malicious,
so I have disabled the service, I wasn't using that function anyways. Very
strange.

Thanks a lot Steve for your help you definetly pointed me in the right
direction on this! Great advice!
Keep on Keepin On.
