unable to log on to the internet from client computer over the net

okay I'm kinda new to this networking stuff as well as posting to newsgroups
so please bare with me
this is probably going to be a long post!

any how this is my problem:

I have 3 computers networked together and the host computerA) has ICS
enabled. It can dial out to my ISP through a dialup connection(this being the
shared connection) with no problems and I can browse the net. Now The problem
comes up when I try to connect to the internet on any of the 2 client
computers(B and C). It happens this way: go into My Network Places(on any of
the client computers)-click view network connections- right click on internet
gateway Icon- click connect: a little box comes up saying "ISP" on "host" in
the title bar then underneith that connecting.... (goto the host while this
is occurring and you can hear it dial out to the isp and go through the hand
shakes then disconnect) After about 10 or so seconds it says ...connection
failed!(on the client computers) And I am unable to log on to the internet.
This happens on both client computers the exact same way. Also I cant access
the printers on the host computer from the clients. Also as of now I can ping
the IP adresses of all the computers on the network from any one of them and
get the correct response no problem. also I can browse the shared folders on
the network from any of the three computers. In order to browse the internet
with a client computer I must manually connect to the internet on (A) first
then I am able to browse the internet with (B) and (C)


Things that I have tried to do to fix this problem are Run the network setup
wizard on each computer starting with the host(verified that ICS was enabled
on host)3 times. That didnt solve the problem. Next I disabled Windows
firewall on all the connections(LAN and Dialup). That didnt work. Then I
disabled Nortons firewall on the host computer. That didnt work. Then I
turned to the help and support native to windows and went through all the
troubleshooters that I could find that looked like they might apply to my
problem. I went all the way through each of them doing what they said to do
all the way to the end of each one and guess what....Thats right no
resolution! this took about 8 or nine hours of running back and forth between
3 computers to check settings, run tests, adjust settings, run some more
tests, adjust some more settings, calling my ISP tech support 3 times to get
some information, check and adjust some more settings, run more tests, and
run through the troubleshooters again. Still not fixed and extremely
frustrated!!!!! so now I come to your newsgroup and spend 5 hours browsing
though past posts Seeing alot of things that might work but find nothing...I
think that applies specifically to my problem. And I just dont know where
to start.

This is my setup so that you can get an idea of how things are set up and
maybe see where I went wrong:

Computer A is running MS windows XP home SP2(Came preinstalled on new Dell
Dimension a730n computer) and is the host computer for my network and has
ICS enabled. It has 2 NIC's 1 is a dial up modem(Agere Systems PCI Soft
modem) The other is a Realtek RTL8139/810x Family FastEthernet NIC(this is
the one that I use to connect to the network). As far as the network settings
go for this computer go they are as follows:

Computer B is a laptop running Microsoft Winds XP Home SP1 With Current
updates as far as I know. It is setup as a client without ICS enabled. It has
3 NIC's on it 1 is a dialup modem(GTW V.92 Voice Modem)another is a standard
hardwired lan connection(Intel(R) Pro/100 VE Network Connection) this is the
connection that I used for the network setup and the last one is a wireless
lan card(Orinoco Wireless LAN PC Card)this one not used.
