Hi,
I'm currently in the process of trying to migrate a Windows 2003 Small
Business Server to Small Business Server 2008.

Active Directory is not replicating and on the original / source
server AD I'm getting the following message :

The attempt to establish a replication link for the following writable
directory partition failed.

Directory partition:
CN=Configuration,DC=SolventGreen,DC=local
Source domain controller:
CN=NTDS
Settings,CN=SGS03,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=C
onfiguration,DC=SolventGreen,DC=local
Source domain controller address:

072b5ecc-9520-40b3-a3d0-84b02636eaf2._msdcs.SolventGreen.local

Intersite transport (if any):


This domain controller will be unable to replicate with the source
domain controller until this problem is corrected.

User Action
Verify if the source domain controller is accessible or network
connectivity is available.

Additional Data
Error value:
8418 The replication operation failed because of a schema mismatch
between the servers involved.

For more information, see Help and Support Center at

any ideas what caused this problem and what the solution is ?

You have to update the Schema in the SBS2003 domain, before it will replicate the objects to the new domain on SBS2008.

Have you run the sourceprep.exe tool from the SBS 2008 DVD on the SBS 2003 box?
Are you also following this article for details of how to migrate? :

Make sure you run sourceprep.exe from the DVD make sure you run it from the disk as there are other scripts that It launches.  This must be done on the 2003 server.

Also ensure the SBS2003 server is ONLY pointing to itself for DNS ensure there are no external DNS servers configured in the properties of the network card.

If you make any changes ensure you restart the NETLOGON service

the migration guide alanhardisty gas posted above from EE member MPECSInc is excellent I have used it with several sucesfull SBS migrations.

I had to reboot both servers to solve this.  I also found that the new destination server had both itself in the DNS entries and the old server.  Removed that.

So no points at all for "Also ensure the SBS2003 server is ONLY pointing to itself for DNS" from my post?
