Step 2:
Configure network computers to use ICS
To get
your Client computers up and working you
must configure them to obtain an IP
address automatically. To do so you must
go to their Local Area Connection icons
(like you did in step 1) and select the
properties for the TCP/IP protocol. You
must then select "Obtain IP address
automatically" and press Ok.
To see if
the computer has successfully received
an IP address from the ICS service, go
to a command prompt and type "ipconfig
/all" (without the quotes you moron!).
Notice that it should say "DHCP Enabled
= Yes", and that the IP address should
be in the 192.168.0.0 range (probably
192.168.0.2, 3, 4 and so on). If it's
not showing yet, you can force a renewal
of the IP address by typing "ipconfig
/renew" and waiting a few seconds.
If you're
using Win9X go to Start/Run and type
"winipcfg" and do a renew from the
window.
Problems
ICS is a
practical feature for people that do not
know how to configure their Internet
Connection Sharing through NAT. But one
thing should be clear as crystal:
ICS is
CRAP!!! ICS is a no-no on operational
networks!
Remember:
-
ICS
might ruin your network! If you have
computers that are configured with
static IP addresses you must now
configure them to get their IP
addresses automatically, and if you
do not do so, they might not be able
to communicate with you anymore (or
create IP address conflicts).
-
ICS
will cause your computer to behave
as a DHCP server, and by doing so it
will stop the regular DHCP service
(if you ever had one running)!
-
ICS
will act as a DNS proxy, and will
render your existing DNS
infrastructure useless (if you ever
had one)!!!
-
ICS
will ruin your Active Directory (no
DNS? No AD!) unless it's run on the
Domain Controller itself, but that's
something you don't want to do, do
you?
-
ICS
will not let you choose what IP
address range to lease to it's
clients. It will only lease the
192.168.0.0 network range, and you
cannot change that.
-
ICS
has very limited port mapping
functionality and low performance
compared to the regular NAT service.
-
ICS is
only good for 2-5 computer networks
that do NOT have running DNS, AD,
DHCP, Web or E-Mail services, and if
that's not the case - consider NAT.
With that
said, carefully consider your situation
and act accordingly. |
