SBS 2008 Migration - Replication Problem

Whilst migrating a customers SBS 2003 server to SBS 2008, I was getting a message saying “Active Directory replication is taking longer than expected”.  I clicked “Wait…” a couple of times, but nothing was happening.

Using the admin share (C$) I was able to access the installation logs on the destination server (from C:\Program Files\Windows Small Business Server) and saw that the section below kept being repeated in the logs:

Setup: DsGetDcName returned: 0
Setup: DsGetDcName returned name: sbs03.mydomain.local
Setup: Expected name: sbs08.mydomain.local
Task:       There are 0 pending replication operations.
Setup:       Attempting LDAP bind.
Setup:       Bind successful
Task: Waiting for replication to finish

First of all, I made sure all the correct services were running on the source server:

• Computer Browser
  File Replication Service
  Remote Procedure Call (RPC)
  Workstation

THis made no difference (but didn’t hurt!).

After trawling the web, I found that there is one registry key on the source server, and two on the destination server that need to be fixed. 

On the source server:
HK_LM\System\CurrentControlSet\Services\NTFrs\Parameters\Backup/Restore\Process at Startup – change the BurFlags key to decimal 4.

On the destination server:
HK_LM\System\CurrentControlSet\Services\NTFrs\Parameters\Backup/Restore\Process at Startup – change the BurFlags key to decimal 2
HK_LM\System\CurrentControlSet\Services\Netlogon\Parameters – change the SysVolReady key to decimal 1.

Now, stop the File Replication service on both machines.

Finally, start the File Replication service on the source server, then the destination server. 

As soon as this happened, the migration continued.
