I am using Windows XP professional and running IIS 5.1.

I am trying to develop a "cookbook" our customers can use when they want to
utilize our proprietary software tools in CGI or ASP environment on IIS.

We have several console mode or command line mode tools which are called in
scripts (in this case perlscript) to manipulate our proprietary-format data
files.

My problem is that when application protection is medium(pooled) or
high(isolated) these tools could not update files already created by a real
user, for example, me(result is an access denied message).

Access is anonymous. IUSR_ is a member of guests.

I am on a network but everything is local - on the same laptop that is
running IIS - and the files cannot be written even if they are in child
folders of \inetpub\wwwroot.

This is a permissions issue. I gave IUSR "full control" access and it did
not seem to help. But when I gave the "nodename\users" group write access
updating was finally enabled. Write access remained enabled even when I then
removed the IUSR explicit access. So it seems the solution is to give the
nodename\users group write access to the files that are be updated by web
scripts.

Is this solution the right one? Will it "travel" to IIS 6.0 running on say
Windows 2003 Server? I'm not confident because I don't understand why giving
explicit access to IUSR did not get the job done.

Thanks in advance for any assistance.
