How do I remove DHCP servers in the authorized list that no longer exist on my network?

Hi, I was going through the list of authorized DHCP servers on my network via the DHCP Server Manager console. (Action/Manage Authorized Servers.)

In the list there are a couple of servers that no longer exist as DHCP servers on my network.

I try to unauthorize them, but I receive a message "There is no such object on the server."

Any suggestions on how I can remove these from the list another way?

My Environment:
Mostly Server 2003 and a couple of Server 2008 boxes.  The servers in question on the list were 2003 boxes.

Thanks in advance.

Have you ever used Netsh to delete a dhcp server that within the authorized DHCP server list says it cannot be removed because object doesn't exist?

I just don't want to screw this up, if you know what I mean.

Thanks.
Look over the link
use the netsh command. before using it, get the exact name which you see in the DHCP console. you will be fine.
I've looked over the link, but it requires the use of ADSIEdit tool, which means I would need to reboot a DC into Recovery DC mode, correct?

I have a Server 2008 R2, could I use ADSIEdit tool without rebooting the server to delete these DHCP server entries that way?
