How to clean up the metadata of deleted domain controllers

With Windows Server 2008, when you delete a DC from the Active Directory Sites and Services MMC snap-in, and all the DC's associated metadata is also deleted. However, on earlier versions of Windows Server the metadata is left around if a DC is improperly demoted.

Please refer to MS KB: How to remove data in Active Directory after an unsuccessful domain controller demotion 

Microsoft also provides a script (Remove Active Directory Domain Controller Metadata Script) with a GUI to delete DCs. The script currently support the following platforms: Windows Server 2008/R2, Windows Server 2003, Windows XP and Windows 2000.
