Wow, what a mess! I have a feeling that either the PPPoE installation on
PC1 is corrupted or you shared the wrong interface or did it incorrectly and
saying this because DHCP is not working, otherwise you would not be getting
the APIPA (Auto Private IP Addr) of 169.254.x.x.

Did you share the correct interface or share it correctly or configure it
correclty? The external interface is what's needed to be shared.

The real way to test it is to get another computer or laptop on the network.
If it doesn't get a DHCP address, then obviously it's PC1 that's not
configured properly. But my feeling at THIS JUNCTURE is that PC1 is the
problem.

No, F&P and MS Client is NOT needed on the external interface.

Take a look at these XP articles. I know you have W2k, but they are very
similar...
