I am of the same mind as Brian in that I like my DCs all to mirror each other so I rebuild them from scratch, it avoids any one off issues that occur on some but not all machines.
While I fully believe a machine that has been upgraded should be the same as one that is loaded from scratch, this has not been my experience through the years though I have no specific K3 stories to tell since I simply stopped following the upgrade processes. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tony Murray Sent: Monday, July 11, 2005 10:23 PM To: [email protected] Subject: RE: [ActiveDir] Install Windows 2003 in a Windows 2000 AD Infrast ructure Just a couple of things to add to what Brian has said. - When all your DCs within a domain are at 2003 the domain won't automatically be at 2003 domain functional level. You need to flip the switch using the Domains and Trusts snap-in. - When all your domains are at 2003 domain functional level your forest won't automatically be at 2003 forest functional level. Again, you need to use the Domains and Trusts snap-in to flip the switch. See this article for more detail (http://support.microsoft.com/default.aspx?scid=kb;en-us;322692#3) - I take Brian's point about wanting to rebuild the DCs from scratch, rather than in-place upgrade. On the other hand it can be a fair bit more effort and I personally have not seen any major problems with an in-place upgrade.

There are some Exchange 2000 issues you must be aware of though: Before you convert to 2003 native mode, the RUS must be running on Exchange 2003 You must import the inetorgpersonfix.ldf schema fix before running adprep /forestprep if you're running Exchange 2000. In general, when you modify the schema under 2000 ALL of your global catalogs are going to perform a FULL resync. This is potentially a lot of bandwidth sucked if you have more than one domain and your links are not optimal. If you have one domain in your forest then this is not an issue. To replace that box, run dcpromo on it to demote it to a member server, and then run dcpromo to promote the new box to a domain controller. Quite easy. I personally recommend rebuilding DCs from scratch in lieu of an inplace upgrade, but that's an issue to tackle on a case-by-case basis.

We want to upgrade them all to 2k3. I have been googling but haven't find the right q-article or step by step that will help me accomplish this. We want to one replace of the servers with new hardware but the other eight are fine and do not need to be replaced. Should I just upgrade them? Can I install the new server with w2k3 and can it coexist with the 2k servers? Any guidance would be greatly appreciated!
