RE: add a DC 2008
Hello NT,
Thank you for posting in newsgroup.
According to the description, you want to add a Windows Server 2008 DC to
the current domain, whose forest/domain functional level is "Windows 2000
native". What your concern is if you have to make it to be "Windows Server
2003" and delete the Windows 2000 DC.
If I have any misunderstanding, please feel free to let me know.
Analysis:
==============
As far as we known, "Windows 2000" forest and domain functional level
supports domain controller that is based on Windows Server 2003, Windows
Server 2003 R2 and Windows Server 2008. We only need to run "adprep
/forestprep", "adprep /domainprep" before we introduce the Windows Server
2008 based computer to the current domain. There is no need for us to raise
the forest/domain functional level. Also, we don't have to demote the old
Windows 2000 DC.
For your convenience, I have list the general steps to extend the
forest/domain schema.
General Steps:
=============
1. Extend forest schema to support Windows Serve 2008 DC by running "Adprep
/forestprep" on the schema master holder.
Please note: you may also run "netdom query fsmo" on the domain controller
to check who is the 5 FSMO . we need to install the "Windows Support tool",
the installation file supports.msi is located in the folder of
f:\support\tools.
2. Extend domain schema to support Windows Server 2008 DC by running
"Adprep /domainprep" on the infrastructure master holder.
3. Optional, if you plan to add a Read Only Domain Controller Later, you
need to run "Adprep /rodcprep" on the schema master holder.
Please note: Adprep utility is in the folder of X:\sources\adprerp on the
Windows Server 2008 installation DVD
4. Verify the schema changes on the any domain controller, please try the
following ways:
You may verify the Active Directory verify the level of the schema by using
the Adsiedit.exe or Active Directory Explorer to view the "objectVersion"
attribute in the properties of the "CN=Schema, CN=Configuration, DC=
<domain>" partition.
The Schema Version ObjectVersion values and corresponding operating system
support level:
13=Microsoft Windows 2000
30=Original release version of Microsoft Windows Server 2003 and Microsoft
Windows Server 2003 Service Pack 1 (SP1)
31=Microsoft Windows Server 2003 R2
44=Microsoft Windows Server 2008
