Thanks Chuck for your reply!
Our LAN requires a username and a password to give the Internet access. I
have only one username and password. A and D can not connect to the Internet
with the same username and password at the same time.
Why will A provide an address assignment on 192.168.0/24, to one of the LAN
computers, if LAN computers are setup to provide a username and password to
connect to a server? Does A provide an address assignment to kopn workgroup
computers only?
I made D connct to the Internet through A, and A and D see each other by
disconnecting our LAN's cable from my switch for the duration of the NSW. The
NSW tried to connect to our LAN, but could not, after my choosing an Internet
connection in the NSW. I had to wait several hours for the NSW to complete
its last step with the copying. How to make the NSW complete faster a next
time?
Why do you write that D is connected directly to the residential LAN? D does
not have a unique username and password to connect to the LAN. D is setup by
the NSW to connect to the Internet through A in the same workgroup kopn.

Dima,

Does A connect to the residential LAN thru the switch? Does D also connect to
the switch?

Let's verify physical connectivity first.

Dima,

If A requires a username / password (WAN ("PPP/SLIP) Interface") for Internet
service, then you'll need an additional network card on A, if you're going to
use ICS to share Internet service with D.

A computer running ICS requires two physical network connections. One
connection gets service, and will be on the residential LAN. The other
connection provides service to D, will have an IP address 192.168.0.1, and will
be on its own separate LAN (not the switch). D has to connect to this separate
LAN, and get an IP address 192.168.0.n/24.

If D is getting an IP address of 10.24.21.226/22, it's on the residential LAN.
Whether or not it gets Internet service with a username / password.

Hello Chuck!
Yes, A connects to the residential LAN through the switch. Yes, D is also
connected to the switch.
Best regards,
Dima

Thanks Chuck for your explanations!
Should I select "This computer connects to the Internet through a
residential gateway or through another computer on my network" or "This
computer connects to the Internet directly or through a network hub. Other
computers on my network also connect to the Internet directly or through a
hub" to connect alternately both computers to the Internet through the switch
with the same username and password and make them be able to use disks of
each other? My username and password gives my computer direct Internet IP
address. The IP address of my computer is seen from the Internet.

Dima

Dima,

OK, I think we're both getting in synch now. That's usually the hardest part.

If you're going to use A as the Internet host for D, you need to:
1) Add a second network adapter to A.
2) Connect A, using one adapter, to the residential LAN.
3) Connect D to the other adapter on A.
4) Run the NSW on A, and select
This computer connects directly to the Internet. The other computers on my
network connect to the Internet through this computer.

http://nitecruzr.blogspot.com/2005/05/using-network-setup-wizard-in-windows.html#ICSHost
Remember to select the right connection for getting the service, and for sharing
the service!
5) Run the NSW on D, and select
This computer connects to the Internet through another computer on my network or
through a residential gateway.

http://nitecruzr.blogspot.com/2005/05/using-network-setup-wizard-in-windows.html#NATClient

Now as far as physical connections, once you have 2 adapters on A, you can use a
switch or a cross over cable between the residential LAN and A, and between A
and D, as convenient. But you do have to have 2 properly setup adapters on A.

Hello Chuck!
Microsoft stoped sending notifications of replies in this group, that is why
I did not see your reply.
Thanks for your directions.
When connecting without the ICS, should I select "This computer connects to
the Internet through a residential gateway or through another computer on my
network" or "This computer connects to the Internet directly or through a
network hub. Other computers on my network also connect to the Internet
directly or through a hub" to connect alternately, not at the same time, both
computers to the Internet through the switch with the same username and
password and make them be able to use disks of each other? A has Windows XP
SP2 Home, D - Windows XP SP2 MCE.
I selected to turn off sharing in the NSW on A because of the NSW's warning,
and now I on A don't have access to the Shared documents folder contents by
myself. How to regain the access for me only? I did not select to turn off
the sharing in the NSW on D (although the NSW warned on D too) to get access
to D's disks from A.
Best regards,
Dima

Dima,

If you follow my procedure, you make this change once, and be done with it. D
will have Internet service, AND A and D will be able to share files. Don't
waste time developing an alternating configuration, get it working once.

ICS will allow A to share Internet with D, and will allow the two computers to
connect and to share files. To use ICS, A needs two network cards. Plain and
simple.

If you follow the above steps, 1 - 5, properly, and everything doesn't work, run
"browstat status" and "ipconfig /all" on each computer, and diagnose the
problem. Read this article, and linked articles, and follow instructions
precisely (download browstat!):

Don't waste your time and mine trying to reconfigure to share files, and then
again to access the Internet. Get it working properly, once.
 
Thanks Chuch for your directions.
The A is a notebook. I cannot add a second NIC to it.
I selected to turn off sharing in the NSW on A because of the NSW's warning,
and now I on A don't have access to the Shared documents folder contents by
myself. How to regain the access for me only?
Should I agree to the NSW's warning about the file sharing on A and turn the
sharing off?
When connecting without the ICS, should I select "This computer connects to
the Internet through a residential gateway or through another computer on my
network" or "This computer connects to the Internet directly or through a
network hub. Other computers on my network also connect to the Internet
directly or through a hub" to connect alternately, not at the same time, both
computers to the Internet through the switch with the same username and
password and make them be able to use disks of each other?

Dima,

Your next solution, then, would be to get a NAT router, and configure it as a
PPPoE client, with the username and password from A. You then configure BOTH A
and D as
"This computer connects to the Internet through a residential gateway or through
another computer on my network".

That's hoping that the Internet service used on the residential LAN is standard
PPPoE.

If you continue to connect A to the residential LAN (thru the switch), and
select
"This computer connects to the Internet directly or through a network hub. Other
computers on my network also connect to the Internet directly or through a hub"
you will be running A as a rogue DHCP server on the residential LAN. Whoever
owns the residential LAN will have problems with that.

If you have only one account, I'm sorry for you. You CANNOT have one account,
use a switch, connect multiple computers, and share complete Internet service to
another computer, as you're doing.

You could run a proxy server on A, and connect D thru the proxy. A proxy server
will share specific services, and only with software on D that supports a proxy
client.

Analogx Proxy is one free solution that you can try. It supports HTTP (web),
HTTPS (secure web), POP3 (receive mail), SMTP (send mail), NNTP (newsgroups),
FTP (file transfer), and Socks4/4a and partial Socks5 (no UDP) protocols.

Thanks Chuck for your very practical knowledge.
I have found D-Link DUB-E100 USB NIC for my notebook A and connected to A.
I followed your directions: selected "This computer connects directly to the
Internet. The other computers on my network connect to the Internet through
this computer" on A. I selected "This computer connects to the Internet
through another computer on my network or through a residential gateway" on
D. Now D gets the Internet through A! A and D connect through my straight,
not crossover cable without the switch!
NWS warned me to turn off the sharing on A. Should I turn the sharing off on
A? I wanted to have access to A disks and a printer from D too. A has Windows
XP Home SP2.
Best regards,
Dima

Dima,

I suspect that it's telling you to disable file sharing on the network
connection that goes to the residential LAN. What services do you require
there, anyway?
