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.

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

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.0.75
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1

I have looked at a dozen web pages that tell you how to set up ICS and
troubleshoot it. But they all seem to be about the same and mostly the
troubleshooting involves checking your settings.

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.
