I apologize...
Here are the details:
Each site will have a Windows 2000 Pro workstation & a
server. The sites are 10-12 miles apart & the servers
need to talk to each other...
Each site MUST have Internet access...
Ok, this isn't so much network "design" as it is finding
a method of connect to (very simple) networks over a
serial WAN or VPN that is affordable to you.
Do you envision buying a T1, ISDN, modem or what
for connecting them?
Will you consider using the (required) Internet connection
to setup a VPN tunnel between the two sites instead of
addition hard lines (T1 etc.)?
There will be a database on each server & they have to
upgrade each other...
Probably not much traffic (based on the other details)
but one never knows what "update each other" means
until one asks, so is this very must data that will be
changed?
SQL server can replicate. Most other "large" database
systems can too.
There are 3-5 Users per site...
So each site is pretty trivial.
As to Windows Domains this is ONE DOMAIN,
two Sites (Sites and Services), with (at least) one
DC/DNS/WINS server at each site.
All computers (servers too) will be "clients" (on
NIC properties) of their local DNS and WINS servers
FIRST, the remote server (optionally) second.
I believe ALL resources should be at the site that's
closest to my location, but I am considering a
distributed network...
What does that (distributed network) mean (to you)?
It's going to be distrubuted by the very nature of being
a WAN, or did you mean something specific like using
DFS?
With ANY network holding a companies business,
security is very important...
So a direct connection or encrypted VPN is essential.
You will likely find that a L2TP/IPSec VPN is secure
enough for your needs even crossing "the Internet."
I am considering McAfee AntiVirus Suite...
I am considering a Backup Server & a Web Server...
You will likely want to perform the backups and
software updates (including anti-virus) locally, i.e.,
separately at each site.
I am considering 3Com products as a way to tie this
network together...
The manufacturer is not nearly as important as the
media/physical (or VPN) connection method.
