When you install the FrontPage Server Extensions to an IIS virtual server
or a virtual directory that is mapped to a UNC path on an NTFS partition,
the following message appears:
Your web server's configuration will allow anyone to author pages on your
web server once the extensions are installed. To fix this, stop installing
the extensions now, reconfigure IIS to use an NTFS partition and then use
the FrontPage server administrator tool to install the extensions.
Are you sure you want to install the extensions? Yes or No.
This message is only partially correct. In a UNC path configuration, it is
not possible to configure permissions that provide adequate security. When
you point a virtual root or virtual server's home directory at a UNC path,
you have to give IIS the account to use when accessing the share.
Impersonation as an authenticated user or the anonymous account is not
done when touching files on the UNC; all access to the files is done as
the single specified user. For this reason, the drive works similarly to a
FAT partition. You can turn anonymous access on or off, but even if it's
off, any user with a valid Windows NT account has as much access to the
content as any other. Therefore, configuring FrontPage Webs on a virtual
server or virtual directory that is on an NTFS partition is not supported.
The part of the error message that states you are not using an NTFS
partition is incorrect, and does not apply to this situation.
