Multiple DHCP entries in Active Directory

In the process of upgrading my domain to Windows Server 2003, I have
added 2 Win2K3 DCs to my 2000 domain and have installed DHCP on the 2
new 2K3 servers as well (the 2000 servers will ultimately be
decommissioned). I tried authorizing the 2003 server and deauthorizing
the 2000 server via the DHCP MMC, but the 2K3 box was still not handing
out IPs. So I used netsh dhcp add server <ServerDNS> <ServerIP> to add
the 2K3 server. Somehow it has been added to the directory twice. netsh
dhcp show server lists the same server, dns name, and IP address twice.
So if I try to manipulate it either via the MMC or via netsh, it
reports either that the server already exists if i try to add it via
netsh, or that the object does not exist if I try to unauthorize it in
the MMC. Is there any way for me to delete these entries from AD?
Perhaps ADSIEdit?

Thanks,

Sorry for the typo..

In Active Directory, Authorized DHCP Server entries lie under
"CN=NetServices,CN=Services,CN=Configuration,<AD_ROOT_SUFFIX>". RDN order
got reversed in my previous response.

editing these entries needs extra bit of caution.

The KB article @
http://support.microsoft.com/default.aspx?scid=kb;[LN];Q306925, which
describes a somewhat similar problem, mentions the steps required to
re-authorize a DHCP Server using ADSIEdit. You may want to check those
steps from this article.
