Addition XP User Accounts?

Does anyone know of a good link to find help configuring
how to share a dialup internet connection between User
Accounts (on the same PC)?

I've read everything i can find in the KB, and I still can
find no spceific information as to why my 2nd user can't
browse the net with IE6 or send/receive mail in OE (yet he
can ping yahoo.com just fine.) The primary user has no
such problems. Both users have admin priviledges.

The following gave me a clue, which came from a site other
than MS, but I can't seem to get it set up correctly:

"There is one last step to configuring your XP user
profiles. You have to allow other users on the computer
access to the Internet. XP has a built in feature that
allows you to share the current Internet connection with
other users on the computer or network."

I had no such problems adding ICS and sharing my broadband
connection among several PCs (even mixing Win98 & XPs) but
this will be a off-site system for 3 infrequent users.

Thanks for any suggestions!
