Unauthorizing long-dead DHCP server crashes MMC snapin

I have taken over administering an AD setup after a company merger.

A DC which was also a DHCP server died a couple of years ago but it
is still listed as an authorized DHCP server in AD.

If I right-click on the parent object in the DHCP snap-in and select
Manage Authorized Servers, it appears in the list. If I select it
and click Unauthorize, the snap-in dies. Sometimes it dies instantly
with "the instruction at xxxxxx has referenced memory at xxxxx".
Sometimes the machine freezes for a minute or so and then the snap-in
exits and it unfreezes. Sometimes the snap-in just exits without any
error message. In the first case I get a DrWatson entry in the
Application event log. In all cases I get an Application Popup
entry in the System log.

Anyone know how I can remove the old server from the authorized list?
 
Bring up ADSIEdit

Connect to CN=configuration, dc=domain name, dc=com
CN=Select services
CN=NetServices

Look in the values, in the right pane. I'm guessing you will find your
server.

Use ADSIEDIT to wack it

See http://www.msresource.net/content/view/43/47/ for how to do it
