For a novice it is not an "easy" solution to do this. Requires some
knowledge of whatever server side scripting language your host supports. I
have suggested two solutions (whether they work for you is for you to
determine).
1) Password Protection using an Access database and ASP in Frontpage 2003
(requires a Windows server)
http://support.microsoft.com/default.aspx?scid=kb;en-us;825498 . The
process is outlined in relatively easy to understand steps. Feel free to
post back if you have problems getting this to work *after* following the
instructions listed.
2) Your hosting account might come with a feature such as "protected
folders" accessed through your control panel on your hosting account.
2a) On Linux/Unix this is done through using files called ".htaccess" and
".htpasswd" The protected folders feature on your control panel would
automate the process, all you do is create the user accounts and specify the
folder to be protected (this would seem to be the easiest method rather than
the first suggestion) But again, ask your host if they offer such a thing.
2b) I believe a Windows server could offer the same thing (protected
files/folders) done through your hosts control panel (for your hosting
account)
Again ask your host for more specific information.
Does your host run either Cpanel (
http://www.cpanel.com/) on Unix/Linux or
HELM (
http://www.webhostautomation.com/) on Windows (or any other similar
web-based hosting control panel systems?
The "protected folders" is offered by both these systems (but it depends on
which features your host has enabled I think).
Anyway I hope this gets you started. See your other post also (repeat of my
answer here)
