Hi I have a DC with win2000 server. This DC has got DNS installed which is active directory integrated. This is only DNS on my network and is vital to the client authentication. I am currently on the process of upgrading to Win 2003 server. I have got a new server which I have installed win2003 server, joined the domain and made it DC as well. The problem is that i want to demote Win2000 server and take it out of use completely, but DNS is installed on it and can't do it. In testing environment (troubleshooting same scenario I have got on working environment)I have tried to install DNS on 2003 server but everytime I install DNS it becomes active directory integrated. Then I turn off win2000 server with has got DNS installed, give same IP address to win2003 server but DNS (specially Reverse lookup zone does not register any DC or PC added to the test domain. Also when I log into domain it takes up to 4 minutes to log in. Therefore can you help me with the steps to take: 1. Install DNS on win2003 server and make it DC-GC 2. Demote win2000 server with DNS on it and take it out of domain I have tried some steps from Microsoft site but the outcome is not the same as it says on the white paper Many thanks for any suggestions

Naseri,

A possible solution is that your old IP Address/MAC Address for the server is cached in the mac address table on the switches. To test/fix this, log onto each of your switches and clear the mac address table with this command for Ciscos: clear arp-cache.

Something else you _might_ be able to do is remove the DNS Server from the old Windows 2000 server before shutting it down. I’ve never tried this with Active Directory installed on it, so I don’t know if it will allow you to do it.

Previously when I’ve done upgrades of this sort, I would change the DNS Servers in my DHCP scopes to point to the IP Address of the new server. I’ve never tried to replace the server using the same IP Address. I’m not certain why you want it to be the same. You could make the change to DHCP and wait for all clients to renew their IP Address and get the new DNS server before you take the Win2k server offline.

To answer your questions:
1) Taking over GC is simple, but the rest of the FSMO roles need to also be transferred. To become a GC, go into Sites and Services/Sites/Default-First-Site-Name/Servers/ServerName, right click on the NTDS Settings and Check the “Global Catalog” box. The rest of the FSMO roles can be changed using this link:

or http://www.petri.co.il/transferring_fsmo_roles.htm

2) Hold up on this one until you get all of your roles transferred and are satisfied with your configuration. I recommend taking the Win2k server offline for awhile and making certain that you caught everything (the domain continues to function properly without it) before demoting it. You can demote it using dcpromo from the command prompt and selecting “Remote Active Directory.” Note: This is from memory, you should verify this first.

Hope this helps.

    You should not give the same address to a different DC since the IP addresses is stored in DNS and Active Directory of each DC. Make sure the DNS entry on the network card points to itself. "have tried to install DNS on 2003 server but everytime I install DNS it becomes active directory integrated" - Why would you not want it to be AD integrated? You can change it afterwards to Primary once installed under the Zone properties. I would install DNS on the 2003 box, make sure all records are transfered over and then demote the 2000 server. At that point if you want to you can change the IP, but I would not recommend it.
