File server denied access by Domain Controller: Access is denied because of failure to authenticate

I'm having a problem with a file server authenticating with the domain
controller or allowing users in the domain to map a file share on the file
server. The configuration has been stable for several years; this is the
first time I've seen this happening at the file server.

Server 2 is the domain controller.

Server 1 is the file server.

Users cannot log into Server 1 or map disk drives to file shares. Server 1
has the following event log entries:

Event Type: Error
Event Source: NETLOGON
Event Category: None
Event ID: 5719
Date: 5/22/2007
Time: 5:01:14 PM
User: N/A
Computer: serv1
Description:

This may lead to authentication problems. Make sure that this computer is
connected to the network. If the problem persists, please contact your
domain administrator.

ADDITIONAL INFO
If this computer is a domain controller for the specified domain, it sets up
the secure session to the primary domain controller emulator in the
specified domain. Otherwise, this computer sets up the secure session to any
domain controller in the specified domain.

For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp.
Data:
0000: 17 00 02 c0 ...À

Server 2 (the domain controller) has the following log entries:

Event Type: Error
Event Source: Kerberos
Event Category: None
Event ID: 4
Date: 5/22/2007
Time: 4:57:03 PM
User: N/A
Computer: serv2
Description:
The kerberos client received a KRB_AP_ERR_MODIFIED error from the server
host/serv1.xxx.xxx.com. The target name used was cifs/serv1. This indicates
that the password used to encrypt the kerberos service ticket is different
than that on the target server. Commonly, this is due to identically named
machine accounts in the target realm (xxx.xxxxxx), and the client realm.
Please contact your system administrator.

For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp


followed by another log entry:

Event Type: Error
Event Source: NETLOGON
Event Category: None
Event ID: 5722
Date: 5/22/2007
Time: 5:11:37 PM
User: N/A
Computer: serv23
Description:
The session setup from the computer serv1 failed to authenticate. The
name(s) of the account(s) referenced in the security database is serv1$.
The following error occurred:
Access is denied.

For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp.
Data:
0000: 22 00 00 c0 "..À

I'm not sure how to proceed.

I've reviewed KB entries:
http://support.microsoft.com/kb/321044/en-us



http://support.microsoft.com/kb/913327/en-us



http://support.microsoft.com/kb/823659/en-us



http://support.microsoft.com/kb/885409/en-us



but they don't really tell me how to proceed, expecially as I can't find a
duplicate name and there is no reason for the authentication to suddenly
fail.

Both servers can ping the other, which indicates the the network adapters
are functioning correctly. This configuration has been stable for several
years. No "landmark" event stand out as a possible culprit.

It is clear that the domain controller is rejecting the connection but I
don't know why.

Any suggestions?

Regards,
Jim

Sharing Solution::

1. Remove file server from domain (add to a workgroup) via "my
computer/properties"
2. Use active directory/computers and users application to delete file
server from computers container.
3. Add file server back into domain.

The cause of this problem has not been determined.
