Question : Windows 2008 Server Domain isues

I have a 2003 SBS server that functions as the domain controller. I have just recently purchased a new Dell server with 2008 64 bit server installed. I was able to join to the SBS domain with no issus. I then decide to add the new server as an additional DC on the domain. I went through all the required processes as far as adprep with all the functions ie /forectprep and /domainprep. When I ran all these procedures I got all the correct responses from the utilities and proceeded to join the 2008 server. When I run the dscpromo it goes so far as to connect to the domain and gives this message ""To install a domain controller into this Active Directory forest, you must first prepare the forest using adprep.exe /forestprep. The adprep utility is available on the Windows Server 2008 R2 installation media in the \support\adprep folder" I followed the directions that are in the MAy 27th technet article to the letter but wonder if there is something I am missing.

Also as a side note. I may not need to be doing things quite this way and need some guidance. What I really want at the end of the day is to remove the SBS 2003 Server. It is getting old and we have outgrown that server. I want to completely remove it and shut it down. Should I be setting up a new domain and try to setup trust between these domains as from what I understand the SBS server will always be the schema master and no way to move this to 2008. I would really appreciate some advice from those that have tried this and learned from their expreience. Thanks in advance for any advice and instructions you can provide.

You need to run adprep32 on your SBS server adprep is only for a 64-bit install of your current DC which seems not be correct.

So, run adprep32 off the R2 DVD.
