Failed 2003 DC after moving FSMO to new 2012 DC with failed replication

Installed a new Windows Server 2012 Std (gui), joined it to the domain, installed the AD role with DNS and the moved the FSMO roles to new server. I noticed that the replication was failing so I tried a few things suggested on technet and then rebooted the 2003 PDC. When the 2003 boots up it doesn't detect AD and fails to login. The 2012 server is up but it too can't detect AD. I noticed that the SYSVOL and Netlogon shares have gone from the 2003 although the folders are still there. Is there anyway I can resolve this without restoring AD since I'm doing this all remotely (I know that's a bad idea). I can access the UNC paths of the 2003 server and the MMC tools not the registry though.

Thanks,
