Step by Step Windows 2000 to 2008 upgrade

I would like to plan a Windows 2000 AD to Windows 2008 AD Upgrade.  For our environment there is 1 Windows 2000 AD Server.  A secondary server was purchased to accomdate Windows 2008 (64 Bit).  I do not plan to do an inplace upgrade (I know it is not supported) but can anyone recommend a step by step to join Windows 2008 to the 2000 AD, and then transfer the roles - if supported?  Is forest prep / domain prep required, at what point?  I have seen a couple Microsoft articles, but they point to a ton of documents.  The network is very basic where everything is on one server.

Any help would be appreciated.

OK as you say it cant be an in-place upgrade - the procedure is as follows

First install the latest SP on the 2000 machine

Next you need to Adprep your 2000 Domain by running
adprep32 /forestprep    and
adprep32 /domainprep   and
adprep32 /gpprep

to do this from the 2008 DVD on the Windows 2000 DC  - adprep is in the SOURCES folder on the DVD. (note you need to run the 32bit version of ADPrep on the 2000 machine)

Next install 2008 server on the new machine (if necessary) and assign the 2008 new computer an IP address and subnet mask on the existing network. Make sure that the preferred DNS server on new machine points to the existing DNS Server on the Domain (normally the existing domain controller)

Join the new 2008 machine to the existing domain as a member server

From the command line promote the new machine to a domain controller with the DCPROMO command from the command line Select "Additional Domain Controller in an existing Domain"

Once Active Directory is installed then to make the new machine a global catalog server, go to Administrative Tools, Active Directory Sites and Services, Expand, Sites, Default first site and Servers. Right click on the new server and select properties and tick the"Global Catalog" checkbox. (Global catalog is essential for logon as it needs to be queried to establish Universal Group Membership)

If necessary install DNS on the new server. Assuming that you were using Active Directory Integrated DNS on the first Domain Controller, DNS will automatically replicate to the new domain controller along with Active Directory. Set up forwarders as detailed at http://www.petri.co.il/configure_dns_forwarding.htm

You must transfer the FSMO roles to the 2008 machine then the process is as outlined at http://www.petri.co.il/transferring_fsmo_roles.htm

You then need to install DHCP on the new 2008 server (if used) and set up a scope, activate it and authorize the server.

Change all of the clients (and the new 2008 DC itself), to point to the 2008 DC for their preferred DNS server this may be in DHCP options or the TCP/IP settings.

You can then transfer any data to the new server

Before removing the old DC from the domain, run DCPROMO on it to remove Active Directory.
