RE: Another question of win2000 DC to win2003

Hi,

Thanks for posting here, and also many thanks for Meinolf's assistance.

I agree with Meinolf. What's more, from your description, I understand you
want to know how to join a windows server 2003 DC to windows server 2000
domain and how to perform in-place upgrade to windows server 2003. If I
misunderstood, please let me know.

How to join a windows server 2003 DC to windows server 2000 domain:
===========

How to join a windows server 2003 DC to windows server 2000 domain

1. Verify the new server's TCP/IP configuration has been pointed to the
current DNS server.

2. Make the new server become a member server of the current Windows Server
2000 domain first.

3. Upgrade the Windows Server 2000 forest schema to Windows Server 2003
schema with the "adprep /forestprep" command on old server.

Please run the "adprep.exe /forestprep" command from the Windows Server
2003 installation CD on the schema master.

4. Upgrade the Windows 2000 domain schema with the "adprep /domainprep"
command on old server.

5. Run "dcpromo" on new server to promote it as an additional domain
controller in existing Windows 2000 domain, afterwards you may verify the
installation of Active Directory.

6. Make sure the new server's TCP/IP configuration has been pointed to
current DNS server.

7. Please note If DHCP server is running on the Windows Server 2000 server,
and you want to migrate it to the new server with Windows Server 2003,
please perform the following steps to migrate DHCP to the new server.
Otherwise, please directly skip to 12.

====Optional===

8. Export the DHCP database from the current DHCP server using the DHCP
Export Import utility (Dhcpexim.exe). You may migrate the DHCP database to
a Windows 2008 domain controller.

9. Install the DHCP server service on the new server that is running
Windows Server 2003 if necessary. Import the DHCP database to the new DHCP
server

Please refer to:

How to move a DHCP database from a computer that is running Windows NT
Server 4.0, Windows 2000, or Windows Server 2003 to a computer that is
running Windows Server 2003
http://support.microsoft.com/kb/325473

10. Adjust DHCP scope settings to make them use the new DNS server.

11. Unauthorized the old DHCP server and Authorize the new DHCP server and
so that the new one can work normally within Active Directory.

====Optional===

12. Insert Windows Server 2003 Installation Disc in the new server.

13. Run "dcpromo" on new server to promote it as an additional domain
controller in existing Windows 2000 domain, afterwards please verify the
installation of Active Directory.

14. Enable Global Catalog on new server and manually Check Replication
Topology and manually trigger replication (Replicate Now) to synchronize
Active Directory database between 2 replicas.

Please note: It will take some time to replicate GC between DC.
15. Disable Global Catalog on DC2 and transfer FSMO roles to DC2.
How to view and transfer FSMO roles in the graphical user interface
http://support.microsoft.com/kb/255690

16. Verify that the old DNS Server Zone type is Active
Directory-Integrated. If not, please refer to:

How To: Convert DNS Primary Server to Active Directory Integrated
http://support.microsoft.com/kb/816101

Note: Active Directory Integrated-Zone is available only if DNS server is a
domain controller.

17. Install DNS component on new server and configure it as a new DNS
Server (Active Directory Integrated-Zone is preferred). All the DNS
configuration should be replicated to the new DNS server with Active
Directory Replication.

18. Make all the clients change TCP/IP configuration to point to new DNS
server or adjust DHCP scope settings to make them use the new DNS server.

20. It is also a good practice to make the old DC offline in several days
after ensuring everything works fine with the new DC. If so, you may let
the old DC offline by running DCPROMO to demote it.

--->Hi,
--->I was looking for these questions in newsgroup and google but without
--->success:
--->I had run DCDiag and NetDiag in my win2000 DC, without errors.
--->I am ready to make the update. These are my questions:
--->
--->- Can I run adprep /forestprep /domainprep commands only for error
--->testing in a production network? These commands modify something in
--->the Windows 2000 DC that will produce problems?
--->
--->- If I get errors with these commands, and decide to give up with the
--->update, can I go on with my win2000 DC without any problems?
--->
--->- Can I update my win2000 DC to win2003, without interfere with my
--->production environment?
--->Let me explain better: Do I have to make the update at night or I can
--->do it at working hours? Will the users note anything? I am talking
--->about all steps (run Adprep, make win2003 member, dcpromo win2003, DNS
--->install/replication, Transfer 5 FSMO, dcpromo win2000).
--->
--->Thanks in advance.
