Error when running adprep32 /rodcprep, trying to add a 2008 domain controller to a 2003 domain

I'm trying to migrate a Small Business Server 2003 to Server 2008 domain. The problem is when I run the adprep32 /rodcprep command as specified as the final step in Step 3 of this article: https://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2881-Migrate-Small-Business-Server-2003-to-Exchange-2010-and-Windows-2008-R2.html

I get an error "Adprep could not contact a replica for partition..." which is described in detail here:
http://support.microsoft.com/kb/949257 I've also attached the AdPrep.log file for full details.

So when I try to run DCPromo on my new Server 2008 PDC (it's not the PDC yet, but want it to be soon), I get an error saying that /rodcprep hasn't ran so there could be errors if I continue.

Anyone ran into this or have any suggestions on how to help? Can Dsmgmt be ran on server 2003 to help solve this? Assuming it's a partition error. ADPrep.log

Right now all roles are on my SBS server, so haven't moved any roles and I'm running adprep32 from the SBS server from the 2008 CD. So running that query, all 5 roles come back as my SBS server.

What potential problems would I run into if I continue with these errors?

You would not be able to run RODC servers which are Read-only Domain Controllers many techs like myself don't run this until we need to want to have RODC servers. RODC servers are not used much except for security measures in a non secure location
