Chapter 8. Conﬁguring the Computers on Your Network

DHCP service in the server console, you designated a range of IP addresses for DHCP assignment. You also allocated a block of IP addresses for

manual assignment. If you accepted the defaults pre-conﬁgured into the server console, IP addresses 192.168.1.2 through 192.168.1.64 will have

been set aside for manual entry. To avoid duplication, use only those IP addresses when manually assigning IP addresses to your computers.

After conﬁguring the TCP/IP parameters, you may need to reboot your desktop computer to implement the conﬁguration changes. (For example,

most Windows systems need to be rebooted after the TCP/IP conﬁguration has been changed.) Once the settings take effect, your computer will be

connected to the server and to the Internet.

8.2.3. MS Windows workgroup conﬁguration

If you are using a Microsoft operating system, you must ensure that your workgroup is the same as the workgroup name of your server. (The default

workgroup name is your domain name. In a subsequent chapter, we’ll explain how this can be changed using the web-based server manager.) If you

are using the default name, go to the Control Panel, select "Network" and then select "Identiﬁcation". In the ﬁeld for "Workgroup", type your domain

name.

A word about domain names

Once you’ve set up your server, there’s typically a delay of one or more days before your ISP publishes your domain address records (the

domain name or names and the associated numerical IP address) so that the information is accessible to other computers on the Internet. Until it

does, incoming mail won’t be able to ﬁnd you and computers elsewhere on the Internet won’t be able to contact your server using your domain

name (for example, www.yourdomain.xxx). However, on your local network you should be able to connect to your server using the short names

of ’www’ (for web access) and ’mail’ (for e-mail clients).

8.3. IMAP versus POP3 e-mail

There are two common standards for e-mail management, IMAP and POP3. Your server supports both protocols. You will need to select the protocol

that is right for your organization.

POP3 is the earlier, better-known e-mail protocol. POP3 was designed to permit on-demand retrieval to a single client machine. E-mail is stored on

the mail server until you retrieve it, at which time it is transferred over the network to your desktop machine and stored in your e-mail box there.

Beneﬁts of POP3 Drawbacks of POP3

Even when you are not connected to your network, you have access to

the e-mail stored on your desktop.

POP3 was not originally intended to support users accessing and

managing their e-mail from remote systems. Because your e-mail is

stored on your desktop, setting up remote access of your e-mail when

you are at a different computer can be complex.

IMAP e-mail, in contrast, is designed to permit interactive access to multiple mailboxes from multiple client machines. You manage your e-mail on

the mail server over the network. You read your e-mail over the network from your desktop, but the e-mail is not stored on your desktop machine -

rather, it is permanently stored and managed on the server.
