Howdy,

I have several erros in the system event log of my single Windows 2003 SP2 domain controller.

Multiple member computers on the domain are listed in these errors.
I am seeing two similar errors for each computer one second apart in the event log.

Event ID 7
Source KDC
The Security Account Manager failed a KDC request in an unexpected way. The error is in the data field. The account name was [email protected] and lookup type 0x8.

Event ID 7
Source KDC
The Security Account Manager failed a KDC request in an unexpected way. The error is in the data field. The account name was MEMBERNAME$ and lookup type 0x8.

The Lookup Types are also different, I have 0x8, 0x28, 0x0, 0x20.

I am also receiving other authentication errors in the same time frame as all of the KDC errors

Event ID 5722
Source NETLOGON
The session setup from the computer MEMBERNAME failed to authenticate. The name(s) of the account(s) referenced in the security database is MEMBERNAME$. The following error occurred: Access is denied.

I have run dcdiag /v to see if there was something wrong with Active Directory, but all tests passed. I also ran netdiag /v and it appers all of those tests ran.

Any ideas on where to start for this issue?

Thank you,
Keith
