Generally, most people share files in Windows7/Vista for the convenience of password protection 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.
Because 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 not only the corresponding permission but also the corresponding permission. Also subject to the permissions of the file xp system NTFS. Therefore, you must also add the appropriate NTFS permissions in the security tab of the drive, and the drive formatted under Windows7/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 Windows 7/Vista are different from XP.
The default permissions for Windows 7/Vista formatted drives are:
Authenticated Users This is not available for XP.
System administrators Administrator group.
Users Restricted User Group.
The default permissions for XP are:
administrators Administrators 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 Windows 7 System/Vista is this group. For example, if you are an administrator, the folder owner you create is the administrators group. So the folder created under Windows7/Vista does not have the corresponding permissions of CreatorOwner.
Feeling a setting like Windows 7/Vista makes 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 /Properties /Security: in the "Group or User Name" column Click “Edit & rdquo;, then click "Add", in the "Enter the object name to select", enter " Everyone"; point "definite", XP machine can access you in Windows7/Vista The shared drive and folder created. Of course, you don't have to use everyone, you can specify users, and it's safer.
