(http://support.microsoft.com/kb/836023/ )Windows ignores the share permissions that the registry specifies after you install Windows XP Service Pack 1
When you use the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\DefaultSecurity\SrvsvcDefaultShareInfosubkey to configure the default share level permissions, the subkey value is ignored. The Everyone group is given Read permissions to any new network shares.
This problem occurs because of a change that was added to Microsoft Windows Server 2003 to make the default permissions for newly created shares more restrictive than in Microsoft Windows XP. In the release version of Windows XP, when you create a new share, the default permission gives all users full access. When you create a new share in Windows Server 2003, the default permission gives everyone Read access. Because of this change, the SrvsvcDefaultShareInfo value is overwritten with Read permissions.

This fix affects only shares that are created by using the Windows graphical user interface.

For example, if you create a share by using the net share command, the Everyone group is given Read permissions on that share.
