RE: Windows Sharing File Permissions

["Scalcione.David" <SCALCIONED () YANB com>]

Al,

The permissions in the share permissions tab apply to the share. The permissions in the security tab are file/directory 
permissions. The share permissions apply ONLY when accessing the file through THAT particular share. File permissions 
apply not matter how that file is accessed. When accessing a file on a Windows share, share permissions apply first, 
then file permissions. Of course the usual deny the allow order also applies. Share permissions are not very robust or 
granular, and in general don't provide that much security. DO NOT use share permissions to restrict access to files. 
These permissions only apply to that file when accessed through that particular share. If you create two shares that 
can access the same file, with different permissions on each, then you have two sets of permissions that apply to that 
file depending on the way it's accessed though the network. Use share permissions to grant users access to the share, 
use file permissions to grant/deny access to files.

If I'm not making any sense, check out this article http://www.windowsecurity.com/articles/Share-Permissions.html.

Subject: Windows Sharing File Permissions


Hi All,

In Windows, there are two places to set shared folder permissions in the
Folder Property Box, on the Security Tab and on the Sharing Tab under
permissions.  What is the difference between these two? Which one has
priority?  Why are there two?

I know this seems like a very basic question but I cannot find good
documentation on this.

Thanks for your help,
