Hello Cyril,

This will happen if the PDCEmulator role is still on the 2000 DC. So did
you move the 5 FSMO roles to the new 2008 DC? If not you should move the
FSMO roles.

Best regards

Hello

When we upgrade AD from 2000 to 2008, some groups are not created,
like the
group "Serveurs de licences des services Terminal Server" (in english
Terminal server service licence server) in builtin
Did you encounter the problem?
Thank you

Hello Brantley,

You can not do an inplace upgrade, only possible with 2003 SP1 and
higher. See this way:

!!!NEVER START BEFORE HAVING CREATED AND TESTED A BACKUP OF YOUR
DATA/MACHINE!!!

One question first:
Is there also an Exchange server in the domain? If yes which version
and
on what server role?
- On the old server open DNS management console and check that you
are running Active directory integrated zone (easier for replication,
if you have more then one DNS server)

- run replmon from the run line or repadmin /showrepl, dcdiag and
netdiag from the command prompt on the old machine to check for
errors, if you have some post the complete output from the command
here or solve them first. For this tools you have to install the
support\tools\suptools.msi from the 2000 installation disk.

- run adprep /forestprep and adprep /domainprep and adprep /rodcprep
from the 2008 installation disk against the 2000 schema master, with
an account that is member of the Schema admins, to upgrade the schema
to the new version (44), you can check the version with "schupgr" in
a command prompt.

- Install the new machine as a member server in your existing domain

- configure a fixed ip and set the preferred DNS server to the old
DNS server only

- run dcpromo and follow the wizard to add the 2008 server to an
existing domain, make it also Global catalog.

- if you are prompted for DNS configuration choose Yes. If not,
install DNS role after promotion.

- for DNS give the server time for replication, at least 15 minutes.
Because you use Active directory integrated zones it will
automatically replicate the zones to the new server. Open DNS
management console to check that they appear

- if the new machine is domain controller and DNS server run again
replmon, dcdiag and netdiag (copy the netdiag from the 2003 to 2008,
will work) on both domain controllers

- Transfer, NOT seize the 5 FSMO roles to the new Domain controller
(http://support.microsoft.com/kb/324801 applies also for 2008)

- you can see in the event viewer (Directory service) that the roles
are transferred, also give it some time

- reconfigure the DNS configuration on your NIC of the 2008 server,
preferred DNS itself, secondary the old one

- if you use DHCP do not forget to reconfigure the scope settings to
point to the new installed DNS server

- export and import of DHCP database for 2008 choose "netshell dhcp
backup" and "netshell dhcp restore" command
(http://technet.microsoft.com/en-us/library/cc772372.aspx)

- for additional DC's choose the same way, except the FSMO, DHCP and
WINS part

Demoting the old DC's

- reconfigure your clients/servers that they not longer point to the
old DC/DNS server on the NIC

- to be sure that everything runs fine, disconnect the old DC from
the network and check with clients and servers the connectivity,
logon and also with one client a restart to see that everything is ok

- then run dcpromo to demote the old DC, if it works fine the machine
will move from the DC's OU to the computers container, where you can
delete it by hand. Can be that you got an error during demoting at
the beginning, then uncheck the Global catalog on that DC and try
again

- check the DNS management console, that all entries from the machine
are disappeared or delete them by hand if the machine is off the
network for ever

- also you have to start AD sites and services and delete the old
servername under the site, this will not be done during demotion

Best regards

What is the process to upgrade my domain and domain controllers to
Windows Server 2008? Do I just run the forestprep and domainprep
before the install or is there more to this?
