Failure Audit on Windows Domain Controller

[TSPLarry]

We have a TS-QVHL that has been successfully added to our domain - or so we think.  It displays the entire user list correctly and allows access the way we expect it to.  The firmware version is up to date at 1.12.  

 

However, it's producing a Failure Audit message 4-5 times per second in the System log on our domain controller.  The user listed in the event is "admin", the default administrator account for the Terastation.  

 

Any idea why this would be happening?  The NAS was joined to the domain using the Windows administrator account, not "admin".  

 

Here's a sample event:

Are we really the only ones seeing this?  

 

If I drop the box off of the domain, the errors to the domain controller stop immediately.  As soon as I add it back, the errors start up again.  

 

It's definitely joining to the domain, because I can see the entire domain user list on the Terastation when it's joined.  

 

Does anyone else have one of these joined to a domain?  If so, do you see the errors in the event log as described above?  

 

Thanks,

Larry
