Internet Logon Individual Account

I set up my indiviual account without parenteral controls however when I try
to log on the my ISP software (Total Access Earthlink) I am required to us
and Administrative password. To me this defeats the security measure if I
have to as Administrator give my password to and indiviual just so they can
log onto with the ISP software. I also gives me this prompt in the
administrator account however since I am already logged on in that account I
do not have to give a password.
I have found out that if I just use Explorer software I can bypass this in
the individual account however it then creates problems with multiple users
veiwing the same Windows mail account.
How can I allow an indiviual user to use my ISP software to log onto the
internet without giveing them my Administrator password?
