Problem after DC has been rebuilt from scratch


D

Drazen

We had some problems with Windows Server SP4 2000 DC (Server A) and had
to rebuild it from the scratch. Server A was a single DC in the domain,
no BDCs. So what I did was to set up another temporarily Windows 2000
SP4 server (Server B), configured it as additional domain controller in
domain, let it replicate with Server A. Everything went without
problems. Now I had two DCs. So I retired Server A, reinstalled OS,
gave it same IP address as before, same name, everything as it was
before. Then configured it as domain controller again and let it
replicate from Server B. Again everything went without problems. Now i
retired Server B.
Errors started appearing in event log of server A:

Source: SAM
Event ID: 16650
Error: The account-identifier allocator failed to initialize properly.
The record data contains the NT error code that caused the failure.
Windows 2000 will retry the initialization until it succeeds; until
that time, account creation will be denied on this Domain Controller.
Please look for other SAM event logs that may indicate the exact reason
for the failure.
Data: a7 02 00 c0

This is what dcdiag /v returns:

When I try to add new user to domain i get the following error:
"Windows cannot create the object becouse: The directory service was
unable to allocate a relative identifier".

So I suppose it has to do with DC roles being reassigned to computer
which does not exist anymore. Maybe I should do a metadata cleanup +
set up but I'm not sure how to do that.

Heeeelp :)

The server that no longer exists was the RID master. You need to seize
the RID master role on the new server. Ensure that your DC has all the
FSMO roles.

When you say you 'retired' the server, what did you actually do?

You should keep at least two DCs.

Cheers,

Cliff

Retired server A means disconnected it from network, totally
reinstalled it from scratch.
Retired server B means disconnected it permanently from the network.
I know that two DCs shoule be kept but its not possible here.
Ok I'll try to find some info on how to seize the RID master role on
the new server, thank you!

Does that mean you properly 'demoted' the DC using dcpromo, or does that
mean you just literally pulled the plug just like we used to do in NT4?

Note: 'pulling the plug' on it is NOT the way to do it and explains the
issues you are seeing.

If you did literally just pull the plug, in addition to seizing the
remaining FSMO roles over to the existing server that Cliff mention, you
will need to perform that Metadata Cleanup you mentioned to clean out the
old servers' references from the AD database.

216498 - HOW TO Remove Data in Active Directory After an Unsuccessful Domain
Controller Demotion (Metadata Cleanup):
http://support.microsoft.com/?id=216498

Also what complicates it is if you did pull the plug and reinstalled the
previous one with the same name, I'm somewhat suprised that dcpromo allowed
it to be added to the existing network without complaining the name is
already in use.
I know that two DCs shoule be kept but its not possible here.

From the looks of the dcdiag, it seems to me more than just the RID Master
and that it looks like the old machine called "SRVPIS" held ALL five roles.
Look at the extracted error messages from the dcdiag below:
DEL:87e8397c-0635-4f21-84a1-6ce8e71ac598",CN=SRVPIS,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=PIS,DC=local

You're going to need to seize ALL five roles.

Just an FYI, here's what the Roles do:

197132 - Windows 2000 Active Directory FSMO Roles:
http://support.microsoft.com/?id=197132

And this is how to transfer them. For seizing them, it;s the same thing, but
you have to wait to let it time-out when you're in the GUI when it
originally tries to contact the role owner, then transfer it (seize it).
255690 - HOW TO View and Transfer FSMO Roles in the Graphical User
Interface:
http://support.microsoft.com/?id=255690

You can also do it using ntdsutil:

No I have not just plugged the server off the network, instead I used
dcpromo to graefully demote a server.
Now all roles have been seized to domain controller and everything
seems to work correctly again.

Thanks everyone for helping!

I asked that question because you didn't specifically state how you removed
the DCs. If the roles don't transfer over automatically during the dcpromo
demotion process, then that indicates something else is up.

Anyhow, it is great to hear that you've got it working now.
