RE: [ActiveDir] exchange kerberos errors(OT)

[Eric Fleischman]

We have observed this in the past on many systems. It may not be the same issue, but it is very likely the same. It was cleared with a QFE we built as there was a Windows issue at play. We have had threads on this previously: http://www.mail-archive.com/activedir@mail.activedir.org/msg24917.html   I would obtain that QFE and put it on your Exchange server. It will likely clear the issue.   ~Eric     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tom Kern Sent: Saturday, December 03, 2005 5:54 AM To: activedirectory Subject: [ActiveDir] exchange kerberos errors(OT)   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.
