Kerberos Event ID 594 to loopback address

I am getting the following event on the PDC emulator in my mixed mode
Windows 2000 domain:

There is no extended error data. What concerns me is that the target
seems to be the loopback address. Does anyone know what this means?

Thanks.

Any thoughts? Or is there another newsgroup I should post this to?

Thanks.
