trying to decomission a Microsoft Active Directory Certificate Authority getting an error

Hello,

I am trying to decommission a CA per this KB article: http://support.microsoft.com/kb/889250

When I get to Step 3: Publish a new CRL I am getting this error: Directory object not found.  0x8007208d

I might also point out that I recently renamed this DC using the netdom command I followed this article:http://technet.microsoft.com/en-us/library/cc816601(v=ws.10).aspx

I want to completely decommission this domain controller and start from scratch.  But I'm concerned there will still be references to this old no longer working Certification Authority.  Any help would be most appreciated!  Thank You.
