Re: ICS not 100%

I had been using a cable modem and router to connect two computers to
the internet. Then I dropped the cable modem and went back to dial up.
But I have not been able to get the Internet Connection Sharing (ICS)
to work correctly ever since. Sometimes it seems to work ok, but then
out of nowhere, it will stop working and the best I can get it to do is
to let me browse, but my email program won't work (Eudora) and Adobe
Reader hangs on startup. Eudora also hangs on startup. It's almost
like the software is confused and is trying to go through the cable
modem that isn't there instead of the dial up modem.

If it is working but not for some programs then likely it is
a timeout, possibly a DNS issue.

If some services work you have ROUTING (and address translation.)

If some fail, there is something different about those services and
above are the obvious possibilities.

If one service is time-sensitive it might not work. If one service
is connecting to a resource but cannot resolve the name then that
is also a (less likely) possibility.

Another would be that some Ports are being filtered and others
are not but you are very unlikely to get that with ICS unless YOU
set it that way.

The host computer uses 192.168.0.1 as the IP address with DHCP enabled.
The ICS client I am using is 192.168.0.75 at the moment. The router
in between is 192.168.0.101. When I run IPCONFIG on the ICS client it
returns

Seems ok.


Any ideas on how to get this working again? Normally I putz with it
for a while and it seems to start working again. This time it has been
down for two or three days and I have rebooted a dozen times and done
everything I can think of to get it going again.

Yes, two ideas:

1) Break it down to something SIMPLER -- simplify, simplify, simplify:
Use tracert to see "how far" you get, try IP versus DNS name for
various connection types, connect to POP or SMTP servers with
telnet (or better is "nc.exe" -- netcat) to connect to the specific
service
ports and thus eliminate complicated programs like email client
software.

2) Did you remove the old NIC (for cable) AND perhaps recreate the
Dial connection and SHARE it as part of the configuration (since
that method almost always does it correctly.

Check firewall settings and make sure the INTERNAL (NIC) LAN
connection is not firewalled. Also check any third party firewalls.

Check OS version and all hotfixes etc.
