Hi All,
My scenario is like this.
one w2k computer(member server) in the domain xxx.com.
one w3k server which is AD-I domain xxx.com.
one standalone pc(XP Pro)ruuning ICS.(All connected with a netgear switch)

I have done the same way as it is said on the microsoft link.
My 2003 server is the first D.C running AD-I DNS for xxx.xom
My 2000 server which is also joined to the xxx.com domain.Then i ran the DNS
server on the 2000 server making it as a primary zone with the file name as
the same as the AD-I domain and alternate DNS server as the ISP DnS server ip
address which is running on the Xp pro(Which has ICS).Also I changed the
forwared with the ISP Dns Server (in w2k dns server).Still I am not having
the
luck to connect internet????

i don't know why still it is not connecting to the internet??
please help me to solve this problem

thanks in advance

The only place on your domain your ISP's DNS server should be listed is as a
forwarder on your AD DNS server. setting is as secondary on a client will
cause problems.

so what your saying that If I configure forwarder on my AD DNS server I can
get the internet connection.but my broadband is connected to the XP pro which
is not a client on the domain.but still I am running ICS.Do ou think it is
enough for getting internet connection to my 2000 server(member server) and
2003 server(AD Domain).
 
my broadband is connected to the XP pro which
is not a client on the domain.but still I am running ICS.

Does this computer get Internet access?

If so try forwarding to the IP address of this computer.

If this computer can get Internet resolution, it must have access to a
public DNS server. You need to provide your domain with access to a public
DNS server.

But how can i forward the address of the Xp pro cause it is not a dns server.
I have configured the ip address of the ISP's DNS as a forwarder.still no
luck!!!
I do believe this is a simple scenario but i can't figure it out??
 
ICS clients must be configured to use the ICS host for their default gateway
and DNS server. This causes the ICS host to act as the gateway to the
Internet for the client and takes care of resolving names for the client.

XP ICS uses the 192.168.0.X range of IP addresses. I would statically input
the IP addresses, DNS, and default gateway on a client. Use 192.168.0.100 to
192.168.0.200 range for your clients.

If the XP computer with ICS can browse the Internet. setting it as the
default gateway and DNS server should get you connected.

To add to that:

1) First, make sure your XP Pro box can connect to the Internet. By default,
Windows will change it's local IP address to 192.168.0.1. If you can, leave
the LAN settings just as Windows sets them up.

2) TO log on to the domain from the W2K box, you need to use your DC as it's
DNS server. If you want to be able to resolve names on the Internet, you'll
either need to configure your local DNS server to resolve public names, or
you'll need to forward requests to your ISP's DNS server. Obviously, your DC
will need Internet Access i order to fo this.

3) Your W2K host AND your 2K3 server must use the XP pro box as it's Default
gateway.

Try these Settings:

W2K : IP Address 192.168.0.2
Mask 255.255.255.0
Gateway 192.168.0.1
DNS 192.168.0.3

2K3: IP Address 192.168.0.3
Mask 255.255.255.0
Gateway 192.168.0.1
DNS 192.168.0.3

Remove the forwarder(s) from your DNS settings on the server. Look at your
forward lookup zones and see if you have a "." Zone. If you do, delete it.

From all computers go to the command line and type

ping 192.168.0.1

If that doesn't work you have a local LAN or settings problem. If it does
work:

ping 208.20.248.1 (or any Internet address tha you know replies to pings).
If that works, you have routing to the world happening.

nslookup google.com

If you get resolution, you're there. If not, check your DNS settings.

hi Kurt,
Now everything is working I can connect to the internet.But I can not ping
192.168.0.1, are you saying that I have to remove root hints from w2k3 dns
server which is the only one D.C.

If I want to remove root hints how can i remove.Do I have to remove one by
one by going to the Root Hints Tab or(2003 Server) ??If I remove root hints
,how can i find the name-to-ip address information which is not resolved by
private domain.

Also could you please give any kind of information or LINKS, which gives me
info about sharing internet connection for 300 users with 2 FTP server,2
Domains,1 SUS server.(Domain environment) in a real world?????


thanks for all.
