Hello,

	Do not use Microsoft product unless I have to so I am not sure if you can do this with IIS. I stick with slackware or BSD systems (open, net and Free).

On my slackware box I have apache install and in the config file there is the following option:

--snip--
#
# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.
#
# User/Group: The name (or #number) of the user/group to run httpd as.
#  . On SCO (ODT 3) use "User nouser" and "Group nogroup".
#  . On HPUX you may not be able to use shared memory as nobody, and the
#    suggested workaround is to create a user www and use that user.
#  NOTE that some kernels refuse to setgid(Group) or semctl(IPC_SET)
#  when the value of (unsigned)Group is above 60000;
#  don't use Group #-1 on these systems!
#
User nobody
Group #-1
</IfModule>
</IfModule>
--snip--

I am not sure if the windows version has this option - it may have something similar.

Michael.

Of course, this is because PHP was invoked by apache, which is being run as a root user (Administrator, he runs apache on win2k3 for some odd reason) but I do not know the remedy. How could he set up his apache/PHP so that only the users of his web hosting service could "do stuff" to their own web directories. I know I am not expl
