LAN sharing for Windows 7 and WinXP

In general, most people share files in Win7/Vista for the convenience of password-protected sharing. 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. That is, the network neighbor can see the shared drive, but the access does not have permission. Since the shared drive can't use the wizard, you can only use the advanced share, but you have already added the permissions of Everyone in the advanced share. How can you say that there is no permission? Because they ignore the fact that the share is subject to the same permissions. Permissions on the file system NTFS. Therefore, you must also add the corresponding NTFS permissions in the security tab of the drive, and the drive formatted under Win7/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.

By the way, the default folder permissions under Win7/Vista are different from XP.

The default permissions for the drive formatted under Win7/Vista are:

Authenticated Users This is not available for XP.

System

administrators Administrators group.

Users Restricted User Groups.

The default permissions for XP are:

administrators administrator group.

Creator Owner The owner of the created folder, which Vista does not have.

Everyone XP has read-only permissions by default.

System

Users

But 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 Win7/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 Win7/Vista does not have the corresponding permissions of the Creator Owner.

Feel the settings like Win7/Vista to make the permissions clearer.

As mentioned above, the following is the solution, one sentence:

Just right click on the shared folder you created or the NTFS format disk on the system /Properties /Security: "group or username"column"edit", then click "Add", enter "Everyone" in the "Enter object name to select " determine ".XP machine You can access the shared drives and folders you created in Win7/Vista.
