Does anyone know a good article dealing with how to
replace a domain controller (physically, with a new box),
which also houses a global catalog, and is a DNS server
for my domain? I have one other DC already on the
network, which is also a GC and DNS.
 
It's not that hard -- bring up the new box with SERVER,
update all Service Packs etc.

Make it a DNS server, secondary to the first one.

DCPromo it (while the other DC is still online).
Make it a GC.
Transfer 5 master Roles if the older DC holds them (PDC Emulator,
Schema master etc.) -- use various GUI MMCs or NTDSUtil.exe to do all five.
Swap DNS roles -- old to secondary; new to Primary etc (if applicable.)

Make sure no clients (or DHCP settings) refernce it as a WINS, DNS, or other
server.

Shutdown older, test. Reboot older and DCPromo it (UNpromo it actually, as
this removes its entried from the AD.)

Remove references to is as a DNS or DC in DNS.
 
Good info, except for one thing. I'm not sure what you
mean by primary and secondary DNS servers. I have two
DC's which are running DNS. Both are Active Directory
integrated, but I don't see any reference to primary or
secondary in either of their properties.

Then it is "N/A" to you -- there are three major types of DNS
servers: Primary (changes records); Secondary (doesn't change
records, just copies them from another of the DNS servers);
and the NEW AD-integrated which can change records AND
replicate those changes with all the OTHER AD-integrated DNS
servers in the "set of AD-integrated servers" for that zone.
