I've been geeting Event ID 675 errors on my DC's lately.
The accounts referenced are the machine accounts of my Exchange servers.
The error is as follows-
Event Type: Failure Audit
Event Source: Security
Event Category: Account Logon
Event ID: 675
Date: 12/2/2005
Time: 3:58:39 PM
User: NT AUTHORITY\SYSTEM
Computer: OPNYC10
Description:
Pre-authentication failed:
User Name: EXNYC02$
User ID: MYDOMAIN\EXNYC02$
Service Name: krbtgt/OPANDCO.COM
Pre-Authentication Type: 0x2
Failure Code: 0x18
Client Address: 192.168.20.1
I'm running a win2k sp4 forest in native mode and exchange 2k in native mode.
I don't know if this is something I should be worried about or not.
Thanks
