Hi
Got a question.
If we have a Windows 2000 Domain and the DC is on the Windows 2000 server,
and then we add a Windows 2003 server and promote this to a DC using
DCPROMO, and then remove the Windows 2000 Server after demoting this DC, are
we in a Windows 2003 Domain in mixed mode.?

Thanks
 
Yes. You need to change from a Mixed mode to a native mode, on the domain
and forest. In ADUC under Domain Functional Level and in ADTrust Manager.
 
Thanks

What if we have exchange 2003 SP1 installed on Windows 2003 servers? Is
there any gotchas ?
 
Hi

Thanks
Got another question.. where can I check to see if AD Domain is ready to be
Windows 2003 Native.?

to be able to add W2K3 DCs, you need to first update the schema. With
W2K AD you only have 2 modes per domain and nothing per forest. With
W2K3 AD the mode term has been changed to "functional level" as that
says it better what it means. The higher the level the more
functionalities you have/get.

You need to check it yourself....

Mixed mode accepts ALL OS versions of DCs

Native Mode only accepts WIndows 2000/2003 DCs. NT4 and lower DCs are
not allowed anymore in the AD domain
 
Thanks Guys for the replies.

Why I asked was that sometime ago in our organisation, they had introduced a
Windows 2003 Server and prompted it as a DC. They had then removed all
existing Windows 2000 Server DCs. We now have only Windows 2003 SP1 DC
servers.
When I look at the Domain Functional level it says the current level is
Windows 2000 Native, and the only option in the available domain function
level is - Windows Server 2003.

We also have Exchange 2003 servers only.
 
Hi guys

I am Daryl Lufor from mauritius

Concerning the fuctional lever of a domain it works like that

if yu have NT Domain Controllers together with 2000 & or 2003 domain
controllers then yu are in mixed mode

else if yu have 2003 and 2000 domain controlers yu can be set in Natve mode

or if yu have only 2003 Domain controlers then yu can set to 2003 mode

one of Advantage of Native mode over mixed mode is presence of Universal
group.

to accomplish the task of raising the functional level right click on the
domain controller in Active Directory pane go to properties and then yu will
find the Functional level

Cheers
