Help in AD

[Mike Metivier]

I have hopefully a simple question. We have taken an old
NT domain and upgraded it to Windows 2000 AD. We upgraded
the PDc for the domain to 2000, got it running on AD,
installed two other 2000 DC and then after everything is
stable, be ran dcpromo on the original PDC. Things seemed
fine. The only problem is that we had a BDC running NT on
the network when we did the upgrade. Now it shows that
this computer is a DC (even though it is NT) in the users
and computers MMC. When we try to delete the server (we
are going to format it and re-use it) through users and
computers (it doesn't show up in sites and services since
it is still NT), it fails with an error "The DSA object
cannot be deleted".

What can I do to delete the old NT BDC?

Please respond to (e-mail address removed)

Thanks!

Hi Mike Please the follow KB,

Have a nice day!

You can use NTDSUTIL to rip the domain controller object
out of the AD by force, or you upgrade the NT4 box to
Win2k, let it DCPROMO, then DCPROMO again to "un-promo"
the thing.

That latter would be the sort of graceful route, although
there is nothing wrong with using NTDSUTIL either, just a
bit more complex and a somewhat dangerous tool.

Hi Mike,

If you need to use NTDSUTIL, follow:

"The DSA object cannot be deleted". You may want to use ADSIEDIT to remove
the object.
