Win7/Vista folder permissions and XP differences

Many friends have removed the password-protected share for convenience when sharing files in Win 7/Vista. This way you need to add the Everyone or Guest permission when sharing the folder. Generally, when you share a folder, it is a wizard. Adding user settings is easy and there is no problem. But I saw a problem when some people shared the drive. In other words, although the network neighbor can see the shared drive, the access prompts no permission. Since the shared drive can't use the wizard, you can only use advanced sharing, but you have already added the permissions of Everyone in the advanced share. Why do you still say that there is no permission? Because they ignore the point that sharing is subject to the permissions of the file system NTFS in addition to the corresponding permissions. Therefore, you must also add the corresponding NTFS permissions in the security tab of the drive, and the drive formatted under Win 7/Vista and the following directories default to no permissions for Everyone and Guest. However, since the permissions of NTFS are automatically matched and updated when sharing by wizard, the general shared folder does not encounter problems. Let's take a look at the default folder permissions under Win 7/Vista and XP. The default permissions for the formatted drive under Win 7/Vista are: Authenticated Users This is not available for XP. System administrators administrator group. Users are restricted user groups. The default permissions for XP are: administrators administrator group. CreatorOwner creates the owner of the folder, which Vista does not have. Everyone XP has read-only permissions by default. System Users, although the specific permissions are somewhat different, there are also differences in the default folder permissions created by default. But the biggest difference is the owner. The folder owner created under XP is the specific user who created the folder, so after setting up the permissions folder, the unknown account displayed by SID will appear after NTFS. The default owner of Win 7/Vista is the group. For example, if you are an administrator, the folder owner you create is the administrators group. Therefore, the folder created under Win 7/Vista does not have the corresponding permissions of CreatorOwner. Feel the settings like Win7/Vista to make the permissions clearer. Solution: Just right click on the shared folder you created or the NTFS format disk /Properties /Security: in the "Group or User Name" column, click "Edit", then click "Add". In the "Enter the object name to select", enter "<;Everyone" point" OK”. The XP machine can access the shared drives and folders you created in Win 7/Vista.
