Logon Error 537

I am getting a lot of the following errors in my 2003 server Security logs.

Logon Failure:
Reason: An error occurred during logon

Caller User Name: -

Can anyone tell me what they're being caused by and how I stop them ?

Is this server a member of an Active Directory? Is it a domain controller? Make sure your time is in sync across the domain.

I'm getting it on all of the servers within the AD domain, both DCs and ordinary member servers.

What about my time question?

Sorry, I completely missed the time question.

I've checked my servers and a couple of them had slipped out of sync. They're syncing up now so I'll see what I get once they're sorted.

Thanks.
