Active Directory.
John,
The reason why you havent really been able to find a source, is that the
answer is "it depends".
Depending on the size of your sites, the amount of data, number of clients,
other applications using DC services etc, you can really have a single
server that does DC, GC, DNS, WINS, DHCP, FP. I really wouldn't worry about
putting DHCP on a server by itself, the load is so small. Out of all of the
infrastructure services, DCHP is probably the smallest load. Client
machines get a dhcp address when they start, and IIRC there are two requests
during the lifetime of the IP address (one halfway though, and one at the
end of the lease). So for a 2 week lease timeout, you have essentially 3
requests to a DHCP server which is nothing to really worry about.
I recently did some AD design work where small sites (up to about 30 uers)
had a single server (Dual PIII 2+Ghz) ran all the functions listed
previously, plus Exchange with no real trouble. For larger sites, my
suggestion would be one "infrastructure server" (DC, GC, WINS, DHCP, DNS),
and "application server(s)" (File Print, Exchange etc).
As long as you design your AD site topology correctly (so that replication
is optimised, and GC placement is relevant for your clients), AD can pretty
much co-exist with most things, its a question of network bandwidth and load
on the server. Other Databases (like Exchange, SQL, Oracle) are really the
main applications you need to be careful with when putting on the same
server as AD, because they can cramp each others style (Exchange and SQL on
the same box for example is very touchy).
If you are thinking or layering other applications onto an AD DC, just have
a read of the requirements. In a lot of cases MS "force" you down a
particular path. For example, SUS (System Update Services), and MOM
(Microsoft Ops Manager) wont run on DC's, so you are forced to put in an
additional server to run these.
so, as for your original question *grin*, I would have one server that does
the "infrastructure" stuff, and another server for FP.
Glenn
