Removing Domain Controller

[Guest]

We had a Windows 2000 peer controller crash (not the
primary controller) and had to replace it. We have gone
through everything we can find to have the new controller
take it's place but after installing active directory we
get replication failures (1265 DNS lookup failed). A
discussion with our former network administrator reveals
that they never got DNS and Active Directory working
right on the primary controller at the start. We do not
want to mess with the primary controller set-up at this
time so have settled on just running the new server as a
member server for now. Since the active directory
uninstall can't be run on the old controller and wouldn't
run on the new controller (replication fails), we now
have two non-existent controllers showing in AD that we
can't remove.

How do we remove them from AD?

You will need to perform a metadata cleanup. See

Hi there,

When I run the metadate cleanup, after I select the server
which I want to remove and type the remove command, I
receive an error message indicated that the object does
not exit!

Note: the DCPROMO on the server fail - never promote to DC
but the object NTDS appears in the AD Sites and Services

Any other ways?

Thanks

You can use ADSI Edit or LDP to remove it.

Hi Jimmy,

I try that methods before but when I try to remove the
object (server) I selected using ntdsutil.exe, I receive
the object does not exit error?

So, any ideas?

Thanks

sorry to but in here but another note on that technote Q21...

this documents the process of removal of the ntds settings of the server
object (cn=ntdssettings, cn=servername, ..) -

what about the server object itself ?? (cn=servername, ...)

Delete the server with Ldp, and don't forget to remove it from the DNS,
Sites & Services etc...

Thanks. Reading the instructions they seem to indicate I
need to be able to connect to the unsuccessfully demoted
server to complete the removal from AD. Unfortunately the
server no longer exists. Is this a problem? As well it
indicates that replication has to have occurred since the
Server was removed. Since we only have the one remaining
controller and it can't replicate to the removed
controller is this going to be an issue?
