LAN, but no Internet Connection

Hello,

I am still having trouble connectioning to the internet from the Client.
From the Host it's no problem.
Deinstalling and reinstalling NetBui doesn't seem to have any affect. I
still had the problem with the Host not being able to ping the itself, so I
experimented with the Norton Firewall settings. Under Network (Firewall)
when I added every know address suddenly the Host could ping itself, but not
he Client - reversed roles ! So I deleted the Firewall altogether and now
both machines can ping themselves and each other - Eureka !
However, believe it or not, the Client can still NOT access the internet.

Does this indicate where the problem could now lie ?
Is there a program that could be blocking this access ?
Is there a bloody setting within IE for either the CLient or Host machine
that could be blocking the connection ?
Does "IP Routing Enabled" only on the Host and not the Host have anything to
do with this ?

Any ideas where to go from here ?

I take it from your previous post that this has been ongoing for a while,

You state that if you remove Netbui then you lose LAN connection, remember
that Netbui cannot be used as a protocol
to access the web with, only TCP/IP can be used, so this suggests a problem
with your TCP/IP stack.

In your previous post you state that you uninstalled your network cards, but
did you remove them along with
TCP/IP? if not remove your NIC and TCP/IP leave them out, then allow your
machines to come to a working state,

Once your machine is back up power it down then replace the NIC, power up
and let the NIC install, this should
replace the TCP/IP stack if not you will need to manually add it.

I assume from your post that you use a dial up connection, so the guest
machine will need to be set up to obtain
an IP address from the Host machine using DHCP, I take it you are quite
confident at networking to be able to do this.

As a rough guide

Host machine IP on the dial up will be set by the dial up connection
The LAN connection will be set to 192.168.0.1 by using the Internet
Connection Sharing,

The Guest machine should get its IP address via DHCP if your using Internet
connection sharing

The IP should be in the range 192.168.0.x where x is between 2 and 254
The default gateway should be 192.168.0.1 if this is not set to this then
the guest wont know how to route
via the internet.

Make sure the guest machine knows it has to use the LAN for it's connection
to the web, do this by running
the connection wizard, found in IE Properties.

Netbui is not needed as your using TCP/IP so don't install it

Once your up and running try pinging each machine from the other.

let us know

There doesnt appear to be anythign in your DNS settings.
Your default gateway is on a different subnet
 
Nik

I hit a similar problem yesterday on an XP Home/XP Pro P2P network. (Gave up
trying to get W2K to talk to XPH!)

Solved it as follows:

1. On the host machine, with the internet connection live, ipconfig/all to
determine the ISP's DNS server addresses (should be two).

2. On the guest machine, enter the IP addresses determined above as the
Preferred and Alternate IP addresses in the TCP/IP properties for the LAN
connection.

I don't know if this is the "approved" method but it worked for me when
nothing else did. I can now access the internet from the guest machine
without any difficulty.

I only have a firewall (Norton) on the host machine and I configured it to
accept comms to/from the static IP address for the NIC (in your case
192.168.0.110) and it seems to work fine. I ran the Symantec security check
from the guest and no problems were reported.

Hope this helps or that you can adapt my solution to your problem.

Barry,
I'll try the ideas given, but yours is easiest as I don't need to pull the
machine apart.

"There doesnt appear to be anythign in your DNS settings. Your default
gateway is on a different subnet"

I manually set all IP addresses, Gateways (and no, I'm not that fit with
networking) - can you let me know how I should set these on both the Host &
Client ?
 
Hello All,

Found the answer...at last.
Seems the stacks (whatever that is) where stuffed. What I did was to
uninstall the NICs, reset the IPs back to "automatically detect", removed
internet access software (shot Norton Firewwall) and powered down the PC.
Removed the NIC and restarted the PC.
Shut it down again, reloaded all necessary software and suddenly it worked..!

Can any one explain why this can sudenly happen after being in use so long
without any problems ? Also, my network card IDs have climbed up to 7. Any
way to bring these back down to where they were ?

Thanks for all your help and suggestions.

Found the solution !
TCP/IP Stacking problem..I simply took the advice and took out the NICs,
restarted, than shut down again, inserted the NICs, and restarted. Of course
I deleted all internet software and Firewall just for luck.
Using only "Automatic detect" and no static IPs it worked.

Any ideas how this can suddenly occur (after 1.5 years) ? and what can I do
to stop this happening in the future ?

Thanks for all your help.

Well, the gateway tells the machine where it should route data in order to
get off its local subnet. Thus, if the gateway is not on it lcoal subnet, it
donest know hot to get off its lcoal subnet to get the gateway. If you see
what I mean. Assuming you're using some form of internet connection sharing,
change the IP address of the non-working machine to be something like:

IP Address. . . . . . . . . . . . : 192.168.1.111
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.110
DNS Servers . . . . . . . . . . . : 192.168.1.110

See how that goes.
