Guest Andrew Hodgson Posted September 10, 2007 Posted September 10, 2007 Hi, I am not very well up on AD - I do what I need to do on it, and it usually works, but if it falls over I usually turn to Google or some books :). Anyway, the situation is at the office, I have a 200 user W2k AD domain with several domain controllers, some of which run DHCP. I need to upgrade these to W2k3R2, possibly running 64-bit Windows. The first question is is there any way of saving the DHCP data, so that when I put the new domain controllers in, I can put DHCP on the relevant servers, and bring DHCP back to those sites? The other question, which is the main question, was how we should do the upgrade. I was originally going to do the upgrade by backing up all domain controllers, then running the forestprep and domainprep utilities on a W2k domain controller from the W2k3 install disk, waiting for the changes to go through the system, then dcpromo the first machine and take it out the domain, reinstall W2k3 on it, and dcpromo it back again, ensuring the FSMO roles get transferred accordingly. However, my boss is on about having a second domain, then setting up a trust relationship between the domains, then moving people onto the new domain, meaning a brand new domain topology, with group policies etc all refreshed. I am not sure whether this is an option for us, since the security ID's of the users may all change, and this goes way beyond my expertise. What would people recommend doing - or do I need my head examining as I have gone down the wrong road? We are using a standard AD, no Exchange, the only addition to the schema by the looks of it seems to be from a biometric authentication product which is no longer in use - this will be removed at the time of upgrade. Thanks. Andrew.

I checked in the console but didn't see anything - will terminal services to the server and check again. > > for the domain upgrade: > How to upgrade Windows 2000 domain controllers to Windows Server 2003http://support.microsoft.com/kb/325379/en-us > > Common Mistakes When Upgrading a Windows 2000 Domain To a Windows 2003 > Domainhttp://support.microsoft.com/kb/555040/en-us/ Thanks for these - I read the first one, but not the second. However, I am still curious as to wether it is better to start with a new domain and transfer the users using the tools on the second support site - namely the Active Directory users move tool, or whether just to upgrade the domain? Thanks. Andrew.
