ICS / (DNS?) Problem with Sharing Client

T

Tad Ashlock

Hello Everybody,

I'm having a problem with ICS on Windows 2000 Pro. It's *almost*
working, but I can't get the sharing client to access a DNS (I
think). I've tried following the online help and searching Google
Groups, but I haven't found anything that solves my problem.

Here's the scenario:

I use a 56k dial-up connection to my ISP on the ICS host. I have an
ethernet connection between the ICS host and the ICS client. I can
establish the dial-up connection and the host can fully access the
internet. The ICS host and the ICS client (both Win2k Pro) can see
each other through the Windows Network (via My Network Places). The
ICS client can ping an IP address on the internet and get responses,
but it can't ping a site by name.

For example, I try to ping Google from the ICS client:

============================================================
C:\>ping 66.102.7.147

Pinging 66.102.7.147 with 32 bytes of data:

Reply from 66.102.7.147: bytes=32 time=187ms TTL=238
Reply from 66.102.7.147: bytes=32 time=156ms TTL=238
Reply from 66.102.7.147: bytes=32 time=172ms TTL=238
Reply from 66.102.7.147: bytes=32 time=172ms TTL=238

Ping statistics for 66.102.7.147:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 156ms, Maximum = 187ms, Average = 171ms

C:\>ping www.google.com
Unknown host www.google.com.
============================================================

So I tried to use the IP address in IE (http://66.102.7.147/), but it
timed out with with the usual "The page cannot be displayed" and
"Cannot find server or DNS Error" at the bottom.

Anybody want to try tackling this one? I've included dumps from
ipconfig, route, and tracert for both the host and the client below.

Thanks,

Hello Everybody,

I'm having a problem with ICS on Windows 2000 Pro. It's *almost*
working, but I can't get the sharing client to access a DNS (I
think). I've tried following the online help and searching Google
Groups, but I haven't found anything that solves my problem.

Here's the scenario:

I use a 56k dial-up connection to my ISP on the ICS host. I have an
ethernet connection between the ICS host and the ICS client. I can
establish the dial-up connection and the host can fully access the
internet. The ICS host and the ICS client (both Win2k Pro) can see
each other through the Windows Network (via My Network Places). The
ICS client can ping an IP address on the internet and get responses,
but it can't ping a site by name.

<snip>

Are you getting any errors in the event log of the client or the ICS
machine?

Are there any services disabled on the client or the ICS machine?

On the client, if you manually set the DNS address (easily done in IP
properties) to 4.2.2.2, does it then work?

Just a note on IP addresses in the browser, that doesn't necessarily mean it
will work using an IP because many sites use the host header (the URL) as a
website identifier in the webserver.

This could also be an MTU issue (not saying it is and MTU issues usually are
ADSL based but you have dialup). See the first link on how to determine if
it is. Other links are more info on the MTU and what it is.
