Internet Connection Sharing through Dialup

[JMZ]

Hi

I'm new here.

I'm trying to setup internet sharing through a dial up connection that is to be shared

to another computer via an ether net connection.

I followed the instructions from http://support.microsoft.com/default.aspx?scid=kb;EN-US;306126

but when I click on the advanced tab it shows firewall settings, but nothing else.

What should be under the advanced tab is "Allow other network users to connect through this computer's Internet connection check box."

but its not there, I'm I missing something or done something wrong.

Thanks
