No DNS resolution with ICS


S

Stephan

My topology:
Two W2K PCs connected through a hub
One of these PCs is connected to the internet via a USB
modem.

I hoped W2K ICS would allow me to share the internet
connetion, but the client is not able to resolve IP
addresses:
- The client successfully pings website IP adresses, but
- The client does not recognise (ping) website names
- Interestingly enough, the client's browser either does
not display webpages using http://<IP address>

Anyone able to help me out?

Assuming AD is not on the network:

1. On PC1, move the "Local Area Connection" to the top of the binding order.
2. On PC1, in "Local Area Connection", specify a DNS address. Somewhat
suprised that it's blank. In your case, specify:
195.241.77.55
195.241.49.33


Tell you what, it's WAY eaiser to spend $50 and get a Linksys DSL/Cable
Broadband Router and let it be the connection to your DSL provider. It will
take a big load of your W2k machine and the best thing, is that your W2k
machine will NOT be directly exposed to the INternet and most of all, all
that WinPoet software (for the PPPoE connection) will not be on the machine.

Thank you, Ace, for looking into this.

Unfortunately, however, after implementing your
suggestions, I still remain with exactly the same symptoms
as before (I continue to suspect a malfunctioning DNS
resolution, but have no clue why so, though).

Please see complete ipconfigs and DNS-netdiags below
(Perhaps the last bit of PC-1's DNS-netdiag looks
suspicious?).

Thanks again,
Stephan

BTW, I am not sure what you mean by: assuming AD is not on
the network.
BTW2: Begin to recognise you may be quite right,
suggesting I would acquire a ADSL router instead, don't
know if this would work with my USB adapter though..

<snip>

I was assuming you're not running Active Directory. It doesn't appear to be,
so don't worry about that part.

If you can ping from the client, but cannot resolve anything with a browser,
whether IP or name, then I would start to suspect there's a proxy setting in
IE Options, connection tab. Check that out and let us know what you see.

Also, I suggested to move Local Area Connection to the top of the binding
order in PC1, because it still shows as the second entry in your ipconfig
/all. I see it doesn't have a DNS address or gateway. No gateway is normal
for the internal interface since the outside interface's gateway is the ISP.
Leave that the way it is. But I would suggest to enter a DNS address in that
interface and move it to the top. You can use your ISP's DNS address for
that (195.241.77.55).

If not sure how to move the Local Area Connection to the top of the binding
order, goto Network & DIalup Connections, Advanced Menu, Advanced settings,
and select Local Area Connection, and click the up arrow so it will now show
at the top of the list.

If for further testing, you can even try to force the ISP's DNS
(195.241.77.55) into PC2 (assuming this is where the problem lies). This
will eliminate the fact if ICS on PC1 is not proxying the DNS request (as
it's designed to do). But check the proxy settings please.

Hi Ace,

I am not sure what you mean when you say you can see my PC-
1 Local Area Connection is the second entry in its
ipconfig/all listing. In my Network & Dialup Connections,
Advanced Menu, Advanced settings, Adapters and Bindings
tab, my Local Area Connection is shown on top, with my
Internet Connection showing right beneath that.

Are you perhaps referring to the fact that I do not use a
domain/DNS suffix in my two-PC LAN, whereas my ISP uses a
Connection-specific DNS Suffix (being tiscali.nl)?

Or otherwise, perhaps you are referring to the "NDIS WAN
CAPI driver" Netcard driver shown on top of the "3Com
Etherlink [...]" in PC-2's "netdiag/test:dns /v" listing.
I do not know why that driver is shown there nor how to
remove it (it seems to be idle anyway) - it was probably
not removed correctly durring some deinstall process
earlier on PC-2.

Proxy settings - None:
IE Options, connection tab, LAN Settings, both checkboxes
on Automatic configuration are unchecked and the Use a
proxy server for your LAN checkbox is unchecked as well.
(on both PC's)

Please note: PC-1 is browsing happily, its for PC-2 that
the resolution problem emerges. PC-2 will not IE browse
nor ping names, allthough it does ping IP addresses ok.

Hi Ace,

I am not sure what you mean when you say you can see my PC-
1 Local Area Connection is the second entry in its
ipconfig/all listing. In my Network & Dialup Connections,
Advanced Menu, Advanced settings, Adapters and Bindings
tab, my Local Area Connection is shown on top, with my
Internet Connection showing right beneath that.

Are you perhaps referring to the fact that I do not use a
domain/DNS suffix in my two-PC LAN, whereas my ISP uses a
Connection-specific DNS Suffix (being tiscali.nl)?

Or otherwise, perhaps you are referring to the "NDIS WAN
CAPI driver" Netcard driver shown on top of the "3Com
Etherlink [...]" in PC-2's "netdiag/test:dns /v" listing.
I do not know why that driver is shown there nor how to
remove it (it seems to be idle anyway) - it was probably
not removed correctly durring some deinstall process
earlier on PC-2.

Proxy settings - None:
IE Options, connection tab, LAN Settings, both checkboxes
on Automatic configuration are unchecked and the Use a
proxy server for your LAN checkbox is unchecked as well.
(on both PC's)

Please note: PC-1 is browsing happily, its for PC-2 that
the resolution problem emerges. PC-2 will not IE browse
nor ping names, allthough it does ping IP addresses ok.

Also tried filling in the ISP's DNS addresses in PC-2's
DNS server address list as second and third order
alternative DNS server address (see ipconfig below).

Thank you so much!

Hmm, no proxy? Ok, I'm starting to think now it's an MTU issue. This is a
common issue with ADSL that I almost forgot about. You may have to do a reg
alteration to make this work, if this is the case. Default TCP/IP MTU is
1500 bytes. Due to ADSL's PPPoE overhead in the header, about 8 bytes is
used for PPPoE, therefore reducing it to 1492. In some cases, it's even
lower, and will cause issues, *possibly* what you're experiencing.. Here's
what I'm talking about and how to check to see what MTU is set, and some
other links on it.

W2k, it should show it in that respect, but it's not in yours. I apologize
otherwise.

As for your modem's USB, I thought that most modems have an ethernet
connection as well as the USB connection. Who is your provider and what
brand modem do you have? I know the Westel that Verizon uses do have an
option to use one or the other.

Sagem USB modem, it is an all-in package provided by
Tiscali (www.tiscali.nl, ISP in NL that usages the Dutch
BaByXL analogous DSL provider). The modem does only
connect through USB.

You think I won't be able to make the W2K DNS resolution
work with this configuration?

Ace, I dare doubt this would solve the problem,
considering the fact I can ping <IP address>, but cannot
ping <website name> from my client. See also some ping
results from the DNS server (PC-1) and the client (PC-2)
below.

There must be something genuinely wrong with resolving
names to IP addresses from PC-2, I would guess..

Stephan

Kevin,

Disabling and than re-enabling ICS (on PC-1) did not show
to have improved the situation (with PC-2), unfortunately.

I am not sure I understand your comment on the
impossibility of having both ICS and a local DNS server on
the same machine, but I have added the nslookups for both
machines in my network below. (please refer to my original
message for ipconfigs of both machines)

Hope this gives you a clue.

Thank you,
Stephan

BTW Before using http://<ipaddress> on PC-2, I first
tested this on PC-1 to make sure the concerned site can
actually be accessed by ipaddress.


PC-1 (which connects to the internet):

C:\>nslookup
Default Server: ns3.tiscali.nl
Address: 195.241.77.55

C:\>


PC-2 (client):

C:\>nslookup
*** Can't find server name for address 192.168.0.1: No
response from server
*** Can't find server name for address 195.241.77.55: No
response from server
*** Can't find server name for address 195.241.77.58: No

Does this machine have a DNS server on it?

Let me explain, ICS has a non-configurable DNS proxy in it that listens on
port 53. a DNS server also listens on port 53 so you end up with binding
conflicts, that's why you can run ICS on a machine with a DNS server on it.
You can however use NAT that is in routing and remote access, as long as you
don't enable the DNS proxy in RRAS.

Not sure at this point, but if the modem doesn;t have an RJ45 connector,
then it can't be used with one of those routers unless it supports USB WAN
connections.

I see what you mean about pinging. But, just for testing, did you alter that
reg entry to just see if it works? You can always *EASILY* change it back to
the original setting, just export that key, then save it as a .reg file. If
it doesn't work, then double click on that file and it will put it back in,
or just change it manually.

Ok... if you already tried it...

Trying to narrow this sucker down. Ok, let's try another tactic... are there
any services turned off on PC2?

Services such as:
DHCP Client Service
TCP/IP NetBIOS Helper Service
Workstation Service
DNS Client service


On PC1:
Is File and Print sharing enabled?
Is there a personal firewall installed?


Has this machine ever been infected, such as with the QHOSTS virus?
http://securityresponse.symantec.com/avcenter/venc/data/trojan.bootconf.html

Just trying to look at all possibilities at this point. Maybe you can force
an IP to:
IP 192.168.0.100
mask 255.255.255.0
gate 192.168.0.1
DNS 4.2.2.2

Then try it again.
Then switch it back to DHCP.

Do you have another machine, such as a laptop, then you can try and put up
on your network as well and see if that experiences the same thing? I'm
trying to narrow down if it's the workstation or your machine set for ICS.
Maybe even switch them around and try it?

Kevin, I don't believe he has DNS running on this box. If he did, he would
be getting the NATHLP error in his event viewer, which I think I asked him
if he was getting any errors. Kind of getting to be a long thread at this
point.

I hope he doesn't have DNS on this machine. That would be the cause of the
whole thing. I was somewhat assuming these are both Pro machines since he
wasn't even sure what I meant by "if AD is running".

Then that pretty much answers my question, unless you have installed
something that has a DNS server in it then you don't have a DNS server.
Have you disabled any services?
Run the command Ace gave you in a command prompt: "net start" (without
quotes) and post the results. This will list the running services.

Have you enabled packet filtering on any interfaces?
Are all ports open?
Packet filtering on interfaces cannot take the place of a good firewall
because it does not allow for port redirection for outgoing connections, and
you have to open too many ports to get functionality. I suggest you use a
firewall or get a good router that has a firewall.
