Same two Domain Names in the same network

[Guest]

I saw today same Windows 2000 Domain Controller (with same domain name) in
the same network having
different roles: one with Exchange role and another one is with AD role.

I think there will be performance problems

Can anyone suggest how to go about and remove one with a safe procedure?

Best Regards,
Sathya

Hello Sathya,

You can have a lot of Domain controllers in one domain, or did you mean the
same servername? So please clarify a bit your naming problem.

Domain name, network name, name of domain controller and name of Exchange
server.

Dear Weber,

Thanks for the prompt reply.

PresentlyDomain name, network name, name of domain controller and name of
Exchange

server.

Domain name:-XYZ.com - Windows 2000
Domain Controller name:- ABC - ABC.XYZ.com ---- AD & exchange Server2000 -
used only for Exchange messaging.

Domain name:-XYZ.com - Windows 2000
Domain Controller name:- DEF - DEF.XYZ.com -- Active AD

Both these domain (XYZ.com) exist in the same network. I hope now it is
clear.

Best Regards,
Sathya

Hello Sathya,

This is normal configuration, so what is the problem?
The kind of configuration you need to work in one domain with different servers
which have different functions, like in your case. One as Domain controller
which is responsible for user configuration, DNS, authentication etc. and
the exchange server which handles the email part of your domain for the users
that are allowed to logon your domain. If they are not in the same domain
it would not work.

Dear Mainolf Weber,

Thanks for the update.

Then can you clarify further. I could see on both the domain controllers
(which are in the same physical site) all the five FSMO roles are running.

Schema, Domain, PDC, RID Pool Manager & Infrastructure. I see performance
issues on the network.

Sathya

Hello Sathya,

The 5 roles are allways on the first installed DC which is correct and if
you only have one DC it can only be on this machine. FSMO roles can only
be on a dDC not on a member server. What kind of performance problems do
you have? Please give some more infos, Event viewer errors etc.

Further to your message

I had checked the FSMO roles on both the DC's

when I use the Netdom query fsmo command

I could see all the five roles in ABC.XYZ.com and in another also DEF.XYZ.com.

Both the DC's are running in the same network(same physical network same IP
range). I came to know from the IT administrator that both are separtely
built -without joining to the main domain; there was issues in migrating
exchange from old server to the new.

I will try to send you the event logs by today afternoon.

Hello Sathya,

As you write now, you have two different domain names and also problems during
migration. So please give the complete story about what happened before and
during the migration. If you give not all information you have, it can happen
that you got wrong information back and something will not work.

Hello Sathya,


I will try to follow:

Old server ABC on 2000 server, DC with exchange 5.5. Then you migrated from
server ABC to DEF. Is DEF also 2000 or 2003? So you added DEF to the domain
and promote it to a domain controller? How did you move the 5 FSMO roles?
Exchange upgrade from 5.5 to 2003 failed and then you switched off both servers?

You started from the beginning on new hardware with installing server ABC
as DC with xyz.com domain name, not using some backup files etc.? Recreated
the users and including Exchange everything is working fine. Anybody can
login and can use mail etc.? So you have also installed a new DNS server
on the new created ABC during the dcpromo?

Then you started again the server DEF which is a DC and DNS server? For what
reason? You have a running Domain controller with anything you need or did
I misunderstood something?

And what did you mean with the 2 different forests? The XYZ.COM is one forest
or two with the same names?

Best regards

Dear Meinolf Weber,

Old server ABC on 2000 server, DC with exchange 5.5.

Built DEF which is a Windows 2000 and added DEF to the xyz.domain. Then
transferred FSMO 5 roles from ABC to DEF using NTDS using graphical
interface.

In ABC Exchange 5.5 was not able to upgrade to Exchange 2003. Switched off
old ABC.

Yes started from beginning on new hardware with installing server ABC as DC
with XYZ.com domain name, not using some backup files etc. Installed Exchange
2003 Recreated mailboxes on this hardware. ran Dcpromo on this server as
well. DNS is enabled. Added DNS suffix for DEF.

I had started initially built DEF server again which is a DC and DNS Server.
This has got AD; that is why. Since this has got the AD which was migrated
from the original server. I meant 2 forests since both has got the same
XYZ.com names.

When I try to see the AD from ABC I can see the AD and exchange objects
clearly. But we don't create any account here. We create exchange object
here. For creating user acccounts we use DEF.

One more observation in Domains and trusts on DEF -- showing ABC as NON
windows kereberos Realm.

Best Regards,
Sathya

Hello Sathya,

So you have now both servers in domain xyz.com?

Did you add server DEF to xyz.com during installation or over "My Computer
properties" or have you installed it, run dcpromo on it and give it also
xyz.com as domain name?

Best regards

Yes, I have both servers (DEF & ABC) in same domain name xyz.com presently in
one network. Yes, during installation joined it to xyz.com; during
installation.

DEF was switched off. When ABC was recreated newly with same name i.e.
ABC.XYZ.com. After Windows 2000 was installed and Exchange 2003 was installed
without any problems. Then switched ON DEF.xyz.com.
