I know this is going to sound stupid, and probably already done...
But has anyone thought of writting a book to help people starting from
square one?
A small, simple book that says "If you want to host your own email and
website, read me" and explain apache + exim/sendmail and IIS + Exchange.
Also explain how to setup dns, purchasing website, etc.
I could imagine a small pocket book from oreilly like that... becuaes
I've met MANY people who want to do that.. but have no clue where to
I'll be the first to admit, when I got hired at where I am now, I had
zero server experiance and a small book like this would have been a god
send, versus learning the hard way (making the obviously stupid
--hindseight being 20/20 -- mistakes).
Just a crazy thought...
If no one has written one, I think when I get off of work tonight, I'll
write up something short and see ya you peeps think (if your intersted).

        Oh brother. You do not know what you are doing, do you?


        1. If you are using the included Internet Connection Firewall
that comes with Windows XP and Windows 2003 server, you do not
understand. You CAN NOT USE THAT! That is a basic basic basic dumb
firewall that is only a stop gap measure.

        2. Generally speaking, (unless you purchased the cheap version,)
ISA 2000 is included with Small Buisness Server 2003.

        3. You are using a Linksys (what, DSL,) basic router that is not
a firewall. 


        Some one needs to take some time and think about security.


        Operating an Exchange e-mail server, or any flavor of e-mail
server on the Internet, REQUIRES dedication and understanding of the
ramifications of doing so. This includes taking basic standard security
steps at the very least.


        For the Exchange server on SBS, disable the ICF and configure
ISA server and publish the Exchange server properly.

        On the other client behind the Linksys, 86 the Linksys router,
break down and get a SonicWall TZ170 and configure the SMTP and POP3

        One is Win2k3 small biz srvr (Not ISA) built in firewall and the
other client has a basic linksys setup.
