Today I had to do a upgrade from my existing Domain Controller, a Windows 2003 R2 Server to a Windows 2008 Server.
The Windows 2003 Domain Controller is configured with a domain upgrade.local, forest functional level is Windows Server 2003 and the domain functional level is Windows Server 2003. This server is also the DNS server for this domain. There’s is one forward lookup zone and I’ve created a reverse lookup zone for the 172.16.10.x Subnet. We’re going to migrate to Windows 2008 Server.
First of all, I’ve installed a second virtual server with Windows 2008 Server and give it a static IP address, a subnet mask and a DNS server.
Now you have to prepare the forest and the domain with the new schema extensions.
D:\sources\adprep\adprep/forestprep and D:\sources\adprep\adprep /domainprep.
(Note: if you want to add a RODC, Read Only Domain Controller, you’ve to run also the following command: adprep /rodcprep. There must be already a Windows 2008 Domain Controller present in the domain before you can add a RODC.)
Now you can run a DCPROMO on the Windows 2008 Server.
The new Windows 2008 Domain Controller is succelfully promoted in the existing domain upgrade.local.
The next step is to move all the FSMO roles to the new Domain Controller. The following settings must be made.
Change the Domain Naming Master Active Directory Domains and Trusts, Operations Master, Change
Change the Schema Master run the following command regsvr32 schmmgmt.dll , now you’re able to add the Schema Snap-in in your Management Console.
Active Directory Schema, Operations Master, Change
Change the RID Master, PDC Emulator and the Infrastructure Master Active Directory Users and Computer, Your domain, Operations Masters, Change
Now all the FSMO roles are transfered to the new Server 2008 Domain Controller. Now we can demote the Windows 2003 Domain Controller by running the DCPROMO command.
After this steps and a copple of reboots, the migration is done! You now have a Windows 2008 Domain Controller.
This place just keeps improving every time I show up. You should truly be proud.
So not really on the same topic as your post, but I found this today and I just can’t resist sharing. Mrs. Agathe’s dishwasher quit working so she called a repairman. Since she had to go to work the next day, she told him, “I’ll leave the key under the mat. Fix the dishwasher, leave the bill on the counter, and I’ll mail you the check. Oh, and by the way…don’t worry about my Doberman. He won’t bother you. But, whatever you do, do NOT under ANY circumstances talk to my parrot!” When the repairman arrived at Mrs. Agathe’s apartment the next day, he discovered the biggest and meanest looking Doberman he had ever seen. But just as she had said, the dog simply laid there on the carpet, watching the repairman go about his business. However, the whole time the parrot drove him nuts with his incessant cursing, yelling and name-calling. Finally the repairman couldn’t contain himself any longer and yelled, “Shut up, you stupid ugly bird!” To which the parrot replied, “Get him, Spike!”
