To perform regular metadata cleanup as stated you use the NTDSUtil command. Another thing i would suggest is make sure that you check your _msdcs.domain.com folder under your FQDN Primary Zone. Check all of the folders in there to ensure that there are no more remnants of this 2003 Domain Controller in any of the SRV records location.
You will also want to make sure that you check site and services as well to ensure that the computer objects are also removed.
In the past using NTDSUtil i have had occasions where these areas where not cleaned up and i had to manually go in a remove these objects. If you see them after using NTDSUtil you can simply delete them.
