Cannot delete orphaned DFS Namespace

I attempted to delete a Windows 2000 Server Mode DFS Namespace from the DFS management but it did not complete correctly. It provided an access error.

I verified my account is a member of Enterprise Admins.

I went into ADSI Edit under CN=Dfs-Configuration,CN=System,DC=domain,DC=com and attempted to delete the Namespace however it gives the following error message.

Operation failed. Error code: 0x5 Access is denied.

00000005: SecErr: DSID-03152487, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0

Does anyone know how I can remove this?
