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.
Source domain controller:
Source domain controller address:
Intersite transport (if any):
This domain controller will be unable to replicate with the source
domain controller until this problem is corrected.
Verify if the source domain controller is accessible or network
connectivity is available.
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 ?
