XP/2K ICS Problems from client (LAN works well)

[Sebastien]

Hello,

I have a problem with ICS on Windows XP Professional on one computer
(server), and Windows 2000 Professional on another computer as a client.
My LAN is fully working, I can share folders between the two computers and
ping each others without any problem.

I'm using two Realtek 8139 10/100Mbps (PCI) Fast Ethernet cards with a
crossover cable. I've disabled the ICF on the server and enabled Simple
File Sharing. Both Windows' are fresh installations (installed two or three
weeks ago), I didn't make much changes on them, just the necessary drivers
(all WHQL) and the Service Packs (for the client I've only applied SP3 to
Windows 2000 due to problems I've read about 3D Studio Max and SP4)

- From the server, I can access to internet, using my ADSL connection.

- From the client, I can ping and tracert addresses on my LAN and internet
but I can't display any website, I can't check my mails or use FTP, I can't
read Usenet either.


More details about my configuration:

-------------------------------------------
LAN settings on the server (Windows XP):

Computer Name: net
Workgroup: LAN

IP address: 192.168.0.1
Subnet mask: 255.255.255.0

I added my clients to %systemroot%/system32/drivers/etc/hosts on the
server:

127.0.0.1 localhost
192.168.0.3 workstation.MSHOME.NET
192.168.0.2 networks.MSHOME.NET


(192.168.0.2 is a Slackware installation I have on another partition of my
client computer, and I made sure that I didn't forget the two blank lines
and the end of the HOSTS file.)

Here is the contents of %systemroot%system32/drivers/etc/hosts.ics on the
server:

192.168.0.1 net.mshome.net # 2008 8 5 22 6 53 59 172
192.168.0.3 workstation.mshome.net # 2003 8 4 28 12 37 54 271

-------------------------------------------
LAN settings on the client (Windows 2000 Pro):

Computer name: workstation
Workgroup LAN

IP address: 192.168.0.3
Subnet mask: 255.255.255.0
Default Gateway: 192.168.0.1

Preferred DNS Server: 192.168.0.1

DNS suffix for this connection: MSHOME.NET


-------------------------------------------

I've already tried, without success, to:
- set my ISP's DNS addresses to the "Preferred" and "Alternate DNS Server"
on the LAN connection on the client
- set the gateway (192.168.0.1) as the default gateway on the server as
well
- use "MSHOME" as a workgroup name
- disable some of my firewall rules (Kerio Personal Firewall 2.1.5)
- disable the firewall itself
- uninstall, physically remove and reinstall the NIC's on both machines


I've also noticed that exactly the same thing happens on Slackware, I can
ping, I do receive Echo Replies and I can tracert URLs, it resolves the
domain names into their IPs but I can't access to internet via any browser.


Any help would be greatly appreciated.

use your isp dns instead of 192.168.0.1. quoted from
http://www25.brinkster.com/ChicagoTech
Can ping public IPs but not web sites

Symptoms: 1. You can ping any public IPs but not web sites. 2. The routing
table and ipconfig look OK but you can't browse any web sites.

Resolutions: 1. Check the DNS, for example using nslookup to
troubleshooting.
2. To test, disable any firewall. If it works after disabling firewall,
re-configure the firewall and make sure the firewall doesn't black port 43..
3. Check the status of winsock.dll, wsock32.dll or download winsockfix to
fix the problem
4. Also try to disable DNS client service if you don't have domain network
or use ipconfig /flushdns to purge the DNS resolver cache.
5. Apply SP.
6. Try to logon another user.
7. Check Event Viewer for any errors
8. Remove and re-install NIC with latest drive.
9. Assign static IP, Gateway and DNS manually.

This is a common problem with DSL shared connections that use PPP Over
Ethernet (PPPoE). Here are some possible fixes. Any one of them
should solve the problem:

1. Install Windows XP Service Pack 1 on the ICS host computer.

2. Find the right MTU setting on the client computers, as shown here:

http://www.annoyances.org/exec/show/article04-107

and then make the setting manually on the client computers, or use
DrTCP to make it:

http://www.dslreports.com/front/drtcp.html

3. Download the free RASPPPoE program and install it on the host
computer. Use it instead of XP's PPPoE program. Details at these
sites:

Well, I'm replying to myself to post an update. I've tried all the
solutions different people gave me here and on a site but I couldn't get
ICS to work.

RasPPPoE couldn't install (maybe because my ADSL connection is using
PPPoA?), I noticed I forgot to apply SP1 on XP so I did it thinking it
would solve the problem but it didn't, I disabled ICS and enabled it
again in case it was "not well" enabled or if the settings weren't
correctly written. I also repeated some things like turned off options,
rebooted, and turn them on again.

I thought of configuring XP as a DHCP server but I don't know much about
it, I just configured XP to get automatically an IP, and the same for the
client but I didn't seem to work, maybe I forgot to do something.

I'm finally decided to buy a modem-router, not only because of this ICS
problem but also because I thought of connecting a third computer when
ICS would work, and I won't have to use my (horrible) modem.

The Netgear DG814 seems to be exactly what I need and is pretty cheap
actually.

Thanks to Robert, Kenji and Steve for your replies.
