How can I
configure e-mail and message security in
Exchange Server 2003?
Exchange
Server 2003 can work hand-in-hand with
the Windows Server 2003 Certificate
Authority (also known as CA) to provide
message security by offering support for
digital signatures and message
encryption. Both forms of security will
be discussed in a separate article, but
what is important to us is the fact that
both require the presence of a Digital
Certificate to be issued for any user
how will need to use these features.
In order to offer message
security with Exchange Server 2003 you
will first need to install and configure
a CA in your domain.
Note: There may be
scenarios where a company might opt to
use 3rd party issued Digital
Certificates instead of creating their
own, especially when that company's
users will be dealing with
out-of-the-company users, exchanging
encrypted e-mail messages between
themselves and these outside users. This
is because the outside users might not
be willing to trust the company's
internal CA.
Step 1: Install the
IIS Service
In order to install the
CA you will first need to install IIS on
a Windows Server 2003 computer. This
server does NOT need to be the Exchange
server, and in fact can either be one of
your Domain Controllers or any member
server. On Windows Server 2003 IIS is
not installed with the default Windows
2003 installation.
