- SBS 2003 - How to configur it, manage it etc.
- Exchange 2003 - Want to know how it works, how to set it up on the domain controller.
- Network infrastructure - Want to know why there are so many cables, which some seem to loop into two switches ( patch panels? ) and anything else regarding them.
Best way to learn
SBS2003 is to have a play with it. As has already been stated in the thread, get a copy, get a spare (or virtual) machine set up, and just go through the install. SBS is a funny beast (and not reagarded by many as a "proper" server 2003 install) which wants to hold all the
FSMO roles itself. In short, it doesn't play well with other servers
at all.
If you are mainly working with SBS, then
exchange, will be part and parcel (as I said before, SBS is odd) of the package. Play with it, get to know about connectors, how to configure mailing domains, and how the mailboxes are attributes of the users within
active directory (users & computers applet).
You'll need to know about
DHCP,
DNS,
WINS, and perhaps
RRAS (Routing & Remote Access).
As for the
networking aspect, it seems quite strange to me that you see lots of looped back connections with mutiple switches and redundant links in an SBS environment, as surely to god, the infrastructure would be overkill for the type of enviroment SBS can serve. Anyway, you are correct in calling the panels in the cab
patch panels. The cables from the rear of the sockets will most likely be traced through the walls/ceiling to form structured cabling for the building, used for both
voice and
data comms usually. You'd then use the patch panels to "patch in" the wall ports to a
switch (data) or
PABX/PBX (voice). If there are any redundant links (multiple paths in a
star topology network, between switches), then they should be running
spanning tree protocol, to avoid packet duplication, and eventual network flooding. You may also want to look up
VLANs,
Port Mirroring,
Teaming etc etc etc.
As has already been said, the field is massive, and the training for it can vary heavily depending on your working environment. But there is certainly nothing wrong with having a play off your own back and getting a feel for everything. Plenty of tutorials out there on sites such as Petril, Experts Exchange, MSExchange.org, etc etc.
