Security Event Log Critical Error: Event ID 680

SBS 2003 is generating critical errors in the security log as follows:
Logon attempt by: MICORSOFT_AUTHENTICATION_PACKAGE_V1_0
Source Workstation: Server-01
Error Code: 0xC0000064

I had recently changed the admin password so I may have missed updating a service logon but everything seems to be working. Any ideas on how to track down the problem. Thanks

Thanks... It is helpful but I have not been able to work on the problem for a while. I am pretty sure that there is a service not functioning but everything thing seems working. I need to find what is not working to make sure it isn't critical. I guess the only way will be to go to each service and confirm that it is running. I can't seem to isolate which server the error is coming from.

the error seems to be coming from one server, I have gone through all the services and cannot find the one causing the error. Can it be coming from another server in the network but still show the id of the domain controller?

I am still stumped with this problem. All my service accounts with this user account are running without a problem. I am not sure how to pin it down. I was hoping to see something not working.

The information is helpful but I was not able to pinpoint the problem / source of the logon failure even though the services all seem to be up and running. Thanks
