que puedo hacer?

Los servidores son windows 2003 server (sin SP1)

EN EL VISOR DE DIRECTORY SERVICE :

Event Type: Error
Event Source: NTDS Replication
Event Category: DS RPC Client
Event ID: 1411
Date: 25/02/2006
Time: 14:47:07
User: NT AUTHORITY\ANONYMOUS LOGON
Computer: DC01
Description:
Active Directory failed to construct a mutual authentication service
principal name (SPN) for the following domain controller.

Domain controller:
22a8c68b-eae6-43f0-9dcc-2c2ee0799c2b._msdcs.local.es

The call was denied. Communication with this domain controller might be
affected.

Additional Data
Error value:
8589 The DS cannot derive a service principal name (SPN) with which to
mutually authenticate the target server because the corresponding server
object in the local DS database has no serverReference attribute.


Event Type: Error
Event Source: NTDS Replication
Event Category: DS RPC Client
Event ID: 1645
Date: 25/02/2006
Time: 14:47:07
User: NT AUTHORITY\ANONYMOUS LOGON
Computer: DC01
Description:
Active Directory did not perform an authenticated remote procedure call
(RPC) to another domain controller because the desired service principal
name (SPN) for the destination domain controller is not registered on the
Key Distribution Center (KDC) domain controller that resolves the SPN.

Destination domain controller:
22a8c68b-eae6-43f0-9dcc-2c2ee0799c2b._msdcs.local.es
SPN:
E3514235-4B06-11D1-AB04-00C04FC2DCD2/22a8c68b-eae6-43f0-9dcc-2c2ee0799c2b/local.es@local.es

User Action
Verify that the names of the destination domain controller and domain are
correct. Also, verify that the SPN is registered on the KDC domain
controller. If the destination domain controller has been recently promoted,
it will be necessary for the local domain controller's computer account data
to replicate to the KDC before this computer can be authenticated.
