 Win 2008 Server DC in a Win 2003 Domain
I have a domain win 4 branch office. All DC's are W2K3 and I'm running Exchange 2003. All member servers are W2K3. I need to replace a branch office DC (W2K3). I have no plans to replace any other DC's at this time. Question: is it safe to replace the branch office DC with a 2008 Server without making any other changes/upgrades to the domain. Server will be running AD, DNS, DHCP, WINS.

Answer Wiki:
Technically this should work with a few tweaks but I have not tried it nor would I recommend just doing it in a live environment. Can you do it in a lab first? To have the 2008 machine be a DC, you have to upgrade the schema before, otherwise just add it as a member server. <a href="http://technet2.microsoft.com/windowsserver2008/en/library/15883a88-9a03-46da-8c7d-bc4ed84ff3021033.mspx?mfr=true">See this page for more information.</a> Here is a list of the schema updates needed: Sch32.ldf Sch33.ldf Sch34.ldf Sch35.ldf Sch36.ldf Sch37.ldf Sch38.ldf Sch39.ldf Sch40.ldf Sch41.ldf Sch42.ldf Sch43.ldf Sch44.ldf They can all be grabbed from here: <a href="http://technet2.microsoft.com/windowsserver2008/en/library/9824091d-e659-4619-8051-1c2aa2c2198e1033.mspx?mfr=true">Via microsoft.</a>
