Hi Guys,

I had a win2k domain connected to an old NT4 domain with no problems. Last
week we upgraded thhe RAID cards in both the 2k DCs and they crashed. We
attempted to recover AD from backup, but due to problems and time we created
a new 2k domain with the same name and connected it backup to the NT4
network. The NT4 domain showed only one way replication and as of yesterday
has stopped replicating alltogether - The FSMO PDC emulator has also demoted
it self to a BDC and the NT4 BDC has proted itself to a PDC. Is this to do
with a unique ID for the old win2k domain not matching the new one or
something similar?

Thanks in advance,

Niall

Niall,

You had a WINNT 4 domain and a WIN2000 Domain. I assume that when you say
'connected to' you really mean that you had set up a trust between the two.
Is this correct?

Both of your WIN2000 DCs crashed due to 'hardware problems'? I would
suggest that you should have followed the manufacturer's notes on how to
upgrade from one RAID card to another. With Compaq ( yes, I know - they are
now HP ) it is usually simply a matter of installing the drivers for the new
RAID Card ( just drop in the SmartStart CD and install the drivers for the
RAID card that you are going to install ), turning the machine off, plugging
in the new RAID card, connecting the cable and starting the machine.....I am
sure that it is a bit more involved than that, but that is the general idea.
I would also guess that you did both machines at the same time? You
probably should have done one DC at a time. This way if anything went wrong
you still had your other DC...

Oh, well. All water under the bridge now. I am sure that you know this
now...

So, restore did not go well, either? Another no-no. You should check to
make sure that you have valid backups every so often! But, again, I am sure
that you know this now.

So, you created a new WIN2000 Active Directory. Again, I am assuming that
you mean that you created a Trust between the WINNT 4.0 Domain and the
WIN2000 AD?

The rest of what you wrote makes absolutely no sense whatsoever......could
you please explain? What you are saying is not possible. Are you the one
doing all of this?

Hi Cary,

Thanks for helping.

Sorry if that didn't make sense. The RAID card problem is a long story but
suffice to say we needed to get back operational quickly so we decided to
bring a server up and do a restore. I agree with your "no no's" but
unfortunately we can't go back now.

The old win2k domain had a two way trust to the NT4 domain. We run exchange
5.5 on the NT4 domain.

The old and new Win2k server is/was called TYNDALE and the NT4 Server is
called EXCHANGE

We have this in the event logs:

Event Type: Error
Event Source: NETLOGON
Event Category: None
Event ID: 5723
Date: 21/02/2005
Time: 10:25:13
User: N/A
Computer: EXCHANGE
Description:
The session setup from the computer TYNDALE failed because there is no trust
account in the security database for this computer. The name of the account
referenced in the security database is TYNDALE$.

For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp.
Data:
0000: 8b 01 00 c0

And this one:

Event Type: Error
Event Source: NETLOGON
Event Category: None
Event ID: 3097
Date: 21/02/2005
Time: 17:12:37
User: N/A
Computer: TYNDALE
Description:
This computer is configured to be the primary domain controller of its
domain. However, the computer EXCHANGE is currently claiming to be the
primary domain controller of the domain.

For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp.

The Win2k DC is showing as a backup in the NT4 server manger console on the
NT4 DC, and the NT4 DC is showing as a primary. (I don't know if this is a
red herring or not?) before the win2k dc was the primary and the NT4 was
backup.

How do we get exchange and tyndale to replicate again?

Sorry if this still doesn't make much sense but thanks again for you help -
any ideas?

Niall.
