Checked for an AT job running under the old creds? Seen that often.

Yep, one is the PDCE. That would explain the same event at the same time on 2 DCs. But 
here's the
strange thing. The users log on successfully. They work with no problem for a while 
with apps running
like Outlook (to Exchange 2000), IE, open Office files on a file server, etc. Suddenly 
they can't work
anymore - again, just as if someone else was locking out the account. But the events 
are coming from
the user's own PC only.

Is one of the DCs your PDC emulator? Normally, if a user attempts to authenticate to a 
DC with an
incorrect password (error code 3221225578), that DC will redirect the authentication 
to the PDC
emulator for an "authoratative" response. This covers the case where a user's password 
has changed but
not fully replicated to all DCs. The PDC emulator would know about the change, so 
checking there would
validate the login attempt or reject it if appropriate.

Hi folks,
I have been trying to troubleshoot some lockout events. In every case, the event 
originates on the
user's own workstation (not some other user). There are no associated file object 
failures on the
primary file server. It seems like it is application-based, but I can't nail it down. 
I've been using
Microsoft's AL tools, including EventCombMT, but I can't use the acctinfo.dll because 
the clients are
Win9x. 

Today I noticed for the first time that on 2 DCs, the exact same 5 login failures 
occurred (one
example follows):

681,AUDIT FAILURE,Security,Tue Oct 07 13:13:38 2003,NT AUTHORITY\SYSTEM,The logon to 
account: MYUSER
by: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0    from workstation: \\HIS_PC    failed. The 
error code was:
3221225578    

I was concerned that I didn't think it is normal that 2 DCs would log the same 5 logon 
failures at
exactly the same times. What do you think?

Thanks,
