XP Security

We have a WinXP PC in the office that various people sign on to, each with
their own user ID.

In order to check email and have network access, I need to set these people
up as Computer Administrators, which is a security exposure.  I would rather
they be set up as Limited Users, but then network access doesn't work
properly (it's been a few weeks and my feeble mind can't remember the
specifics).

Isn't there some way that I can do this?  Users need to have network access
but not be able to change any password other than their own.  I've poked
around throughout the Help & Support but can't find an answer.

Thanks.
