Win7, Vista, XP LAN drive sharing question and answer

Q: There are many operating systems in the unit LAN, there are XP, Vista, and Win7. Now I have a problem, that is, XP can see the shared drive in the network neighborhood, but it does not have permission when accessing. Since the shared drive can't use the wizard, only advanced sharing can be used, but the "Everyone" permission has been added to the advanced share. How can it be said that there is no permission? Please give pointers!

A: Because you neglected a bit - sharing in addition to the corresponding permissions, but also subject to the NTFS permissions of the file system. 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 have no "Everyone" and "Guest" permissions by default. However, since the permissions of NTFS are automatically matched and updated when sharing by wizard, there is no problem with the general shared folder.

The default permissions for drives formatted under Win7/Vista are: Authenticated Users (XP does not have this); System Administrators (Administrator Group); Users (Limited User Groups). The default permissions for XP are: Administrators (Administrators); CreatorOwner (the owner of the created folder, Vista does not have this); Everyone (the drive under XP has read-only permissions by default).

One of the main differences is the CreatorOwner. The folder owner established under XP is the specific user who created the folder, so after the NTFS is configured with the reconfigured folder, the unknown account displayed in the form of SID will appear. 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. So the folder created under Win7 /Vista does not have the corresponding permissions of CreatorOwner.

The reason is so much, the solution is one sentence: just click the right mouse button on the shared folder you created or the NTFS format hard disk, and then select "Properties → Security", then " Group or User Name" column "Edit", then click "Add", enter "Everyone" in "Enter Object Name to Select" and click "OK". The XP machine can access the shared drives and folders you created in Windows 7/Vista.
