RE: [ActiveDir] Upgrade to Win2k

Title: Message
You'll want to make sure that either the DNS suffix on the PDC matches your desired Active Directory domain name (abc.net), or that the DNS suffix is blank on the PDC, before upgrading. Otherwise the FQDN of the upgraded domain controller won't match the AD domain name, and the DNS entries for the DC won't register.

Thanks Roger for the method. I am sure this will work. But since my domain controller would contain DNS as well as User and Server Accounts, I guess I have to change the steps a bit.
 
1. Build a new BDC. Get all the user and computer accounts replicated.
2. Configure the DNS with the secondary zones pointing to PDC primary zones ( As u suggested )
3. Get the zone transferred. Change the secondary zones to primary on BDC.
4. Promote the BDC to PDC. ( Put the actual PDC offline )
5. Upgrade it to Win2k.
6. Run the DCpromo.
7. Give the DNS domain name abc.net
 
This should create the srv records under the zone abc.net and do the dynamic updates. 
 
Do u really need DHCP service running ( even though u don't DHCP server in ur domain ) to get the PTR records dynamically updated.
 
Thanks for the steps. I would test them and let u all know.

Since it seems like you want all the abc.net domain, I'd do the following:
 
1. Build the new AD domain controller with the DNS service installed (but don't run DCPromo yet)
2. Configure the Win2k box to be a secondary for abc.net from the NT4 box
3. Wait for the Win2k box to replicate (probably <1 minute, but I give it 20 just in case)
4. Force another pull of the zone (because you can never be too paranoid)
5. Change the zone on the Win2k box to be Standard Primary
6. Change the zone on the NT4 box to be a secondary (I think you need to delete and recreate it to make that change under NT4) - you might need to change the zone settings on Win2k to allow for zone transfers
7. Ensure the NT4 box is pulling the seconday properly
8. Enable dynamic updates on the zone in Win2k
9. Set the Win2k box to use itself for DNS
10. Run DCPromo
 
That's basically what I've done in the past with great success.

Subject: FW: [ActiveDir] Upgrade to Win2k

Hi Rick,
 
Thanks for the reply. The problem I am facing here in upgrade is as follows:
 
I have NT 4 DNS configured with 2 zones say abc.net and abc.com on the pdc. I have lot of records like mx, cname and A records of clients in abc.net zone and my clients also access the application on those machines through browser by giving address http://www.clients.egain.net. My domain name is "test" .
 
Now while configuring active directory,
Scenario 1#
 
If I give new DNS domain name "test.local", it created new zone in DNS as "test.local" with all the srv records in it. 
 
The problem with this configuration is when I join new client to the domain " test.local" or "test", I cant add the host record  dynamically to the abc.net zone. The machine name will also change to "name.test.local" whereas I want it to be "name.abc.net" .
Scenario 2#
 
If i give new DNS domain name "abc.net" . It gives me the error " wizard cannot configure DNS for domain abc.net. However the DNS service was successfully installed. DNS zone already exists." . This way no srv records are created.
 
Please help me what would be the right approach.

The SRV records are essential - AD will not work without it as it advertises the existence and where specific services can be obtained - LDAP, GC, Kerberos, to name but a few.  Regardless of how simple or how complex, the state of DNS must be similar in that a very specific format of what is available (SRV records and the services that they indicate) as well as the format (_msdcs, _sites, _udp, _tcp).

Hi Deji,
 
Thanks for the link. I have gone through it. In the scenario mentioned in it, it stresses more on restructuring the domain name rather then keeping the same configurations. I guess I do have to change my NETBIOS domain name with interest of the zone names already configured in NT 4.0 DNS while giving the new DNS domain name in active directory. I will give it a shot in my test lab.
One thing I would like to ask is that do I really need srv records coz I am having just single domain model with single site and at the max 2 domain controllers.

Subject: [ActiveDir] Upgrade to Win2k

I have to upgrade my network from NT 4.0 to Win2k. My current scenario is:

1. PDC with DNS ( having 2 zones: secondary abc.com and primary abc.net )
2. Domain Name is Test.
3. 2 BDC.

Plan is

1. Install fresh BDC, Configure the DNS on it by configuring the same zones. While creating the zones i would copy the records from the DNS files on PDC and past it into the dns files on the BDC This way i will have my DNS Zones configured with all the records in that

2. promote the BDC to PDC

3. Upgrade to win2k along with ADS

4. What shall i give as "New DNS Domain Name" in order to retain the same setting. I dont want to change the name of the current domain

5. When i will join a new client where his A record would be created dynamically? In test.local zone or abc.net zone ? As all my clients has to be part of abc.net zone. These clients are being accessed by outside world.

Would appreciate if someone can guide me on this or can refer me some good artical on how to upgrade the NT 4 DNS to Win2K DNS keeping the current configurations intact. Or do i have to give the new DNS domain name according to dns zone like abc.net. to get the srv records created under the abc.net zone and whenever new client joins in, its A record would get created in abc.net

Thanks in Advance.
