Re: Internet Access from server

No, you don't need 2 NICs but it does make troubleshooting a little easier
as you can attach a laptop directly to the router and test remote access
(this taking the router out of the equation). It also adds a bit more
secure because if the router is breached, the hacker still would need to get
through the Windows RRAS Firewall.

Thanks for the suggestion. The modem/router has been configured as
192.168.168.1 and the server as 192.168.168.2 with the former defined as
the
gateway and all the others to use the dns srver as .3, .4 , .5, etc .

Since you ar ereferring to an external NIC, do we need to have 2 NICs?

The information you have about using ICS is for a "peer-to-peer" network

'workgroup' of computers). With SBS, you set up a "client-server"
network
(a 'domain' of computers).

It appears that the MT841 is a consumer grade ADSL modem-modem.

As such, the installation guide on speaks about connecting it to a single
PC. Since you purchased SBS 2003, I presume what you want is to join all
your current workstations and laptops to the SBS domain and then have all
computers access the Internet through the SBS server, where the MT 841 is
connected directly to the external NIC of the SBS server. (Again, Window
XP
Home Edition workstations/laptops will not be able to join a domain, so
they
must be upgraded to Windows XP Pro).

This means that you need to disable ICS on ALL other computers and
configure
your network to allow all Internet access to go through the SBS server,
with
the SBS server acting as the DHCP server for the network. The diagram I
mentioned in my previous post will show you the physical connections you
need to make. After the SBS server has been installed and then
configured
via CEICW, you join the workstations/laptops to the SBS domain using the
ConnectComputer wizard.

I suspect the default IP address range in your modem-router is:
192.168.1.x, with the modem-router address (default gateway) being:
192.168.1.1

You will also need to configure "port forwarding" in your modem-router so
that traffic for specific services (such as SMTP email, Remote Web
Workplace, etc.) is routed directly tot eh IP address of the external NIC
in
your SBS server. This appears to be handled by configuring NAT entries
in
your modem-router. The following article shows you how to do this for
your
MT841 modem-router.

Thanks for the reply. I have copied verbatim what Compaq Laptop Support
has
to say about the ICS on XP Home Edition

Quote
Internet Connection Sharing overviewWith Internet Connection Sharing
(ICS),
you can connect computers on your home or small office network to the
Internet using just one connection. For example, you have one computer
that
connects to the Internet using a dial-up connection. When ICS is
enabled
on
this computer, called the ICS host, other computers on the network
connect
to
the Internet through this dial-up connection.

When you are setting up a home or small office network, it is
recommended
that you use the Network Setup Wizard in Windows XP Home Edition to
enable
Internet Connection Sharing. The Network Setup Wizard automatically
provides
all of the network settings you need to share one Internet connection
with
all the computers in your network.

Unquote

Given the above, i have made the Laptop with XP Home function as the
ICS
and
the Firewall.

2. The ADSL modem is Huwei SmartAX MT841. Unable to confirm if it
doubles
as
Router too.

3. ICF disabling . Aren't we risking doing this ? The ADSL modem
features
claim it has an in-built Firewall to prevent intruison. May be this is
a
consoling factor to disable ICF.

4. Th SBS 2003 version is Stanadard and NOT Premium.

Hope this data is useful.

Thanks

Is the ADSL "modem" just a modem or is it also a router? (please give
us
the make/model number).

The Windows XP Home Edition computers cannot join a domain. They need
to
be
upgraded to Windows XP Pro.

ICF should be disabled in favor of using the SBS server for Internet
Access.

Is this SBS 2003 Premium or Standard?

Have SBS Server 2003 and XP Home, Professional clients connected
to a
switch and from switch to ADSL modem. The ICF has been configured on
the
XP
Home client.

The modem as per instruction from ISP has to have x. x.x. 1 with the
SBS
Server forming x.x.x.2 and XP Home ( laptop) as x.x.x 4 and so on.
TCP/IP has been set as follows:
In General tab:
Obtain an IP addres autoaticlly has been CHECKED an

Use the following DNS server has the ISP's server as preferred
server

In the next tab(Alternative Config)
USer Configured box has been checked with

x.x.x.2 ( ie server's iP address given) followed by the
Subnet Mask &
x.x.x.1 (ie the modem's port has been desinated as the Default
gateway]

In the same Alternate config tab,

The preferred DNS server has been given as ISP's server

IS the above resulting in conflict? Pls confirm.

Whereas able to connect from the Xp home and other such clients to
Internet,
able to access only the homepages of addresses from the SBS Server
itself,
but the subsequent transmission of packets do not take place.

Ths server has only 1 NIC card and so have not configured IAS and
ICF ,
which apparently require 2 NIC cards.

What impedes this downstream send of packets from modem to the
Server
browser?

Does one need to have 2 NIC cards as well as Exchange server
installed?
Would appreciate useful feedback on hwre one is going wrong and how
to
rectify the situation and what all services to be checked for this
and
the
sequence too please?

Thanks
