Unauthorizing long-dead DHCP server crashes MMC snapin

[Guest]

Archived from groups: microsoft.public.win2000.active_directory (More info?)

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.

Correct.

And since you are looking you might want to make sure that the DC that is
dead is really dead ( as far as Active Directory is concerned ). Make sure
that it is not still in there. Lookup the Metadata Cleanup.......

Use ADSIEDIT to wack it

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