  23. 23. CONTROLLING NTFS PERMISSION INHERITANCE <ul><li>By default, when you assign permissions to a parent folder, all files and folders in the parent folder inherit those permissions automatically </li></ul><ul><li>You can control permission inheritance on a per-user basis at the parent folder by doing the following: </li></ul><ul><ul><li>Prevent a parent folder from propagating permissions to subfolders and files </li></ul></ul><ul><ul><li>Prevent a folder or file from receiving permissions from its parent folder </li></ul></ul>

  31. 31. HIDDEN SHARES <ul><li>Use a dollar sign ($) at the end of a share name to create a hidden share </li></ul><ul><li>Users must know the exact name and location to connect </li></ul><ul><li>The $ is part of the share name </li></ul>
  32. 32. SHARED FOLDER CONSIDERATIONS <ul><li>The default share name is the same as the folder name </li></ul><ul><li>Use intuitive share names and include comments </li></ul><ul><li>Do not use spaces or names over 12 characters if older networking clients must connect </li></ul><ul><li>When you copy a shared folder, the new copy is not shared </li></ul><ul><li>When you move or rename a folder that is shared, the share is lost </li></ul>

  42. 42. SHARING A FILE WITH OTHER USERS ON THE SAME COMPUTER
  43. 43. CONFIGURING OFFLINE FILES ON THE SERVER <ul><li>To use offline files, the following conditions must be met: </li></ul><ul><ul><li>The shared folder must be made available offline. Windows configures all shared folders to be available offline by default. </li></ul></ul>
  44. 44. CONFIGURING OFFLINE FILES ON THE SERVER (CONTINUED) <ul><ul><li>You must configure the client computer to use the share as an offline resource </li></ul></ul>
  45. 45. CONFIGURING OFFLINE FILES ON THE CLIENT <ul><li>Configuring the client for offline files is a two-part process: </li></ul><ul><ul><li>You must enable the Offline Files feature.

  50. 50. CHAPTER SUMMARY <ul><li>Windows XP Professional Edition supports file compression and file encryption on NTFS volumes only. </li></ul><ul><li>In Windows XP Professional Edition, disk quotas allow you to track and control disk space usage. </li></ul><ul><li>Basic file and folder permissions include List Folder Contents, Read, Write, Read & Execute, Modify, and Full Control. Grant the user the lowest level of permission required. </li></ul>
  51. 51. CHAPTER SUMMARY (CONTINUED) <ul><li>When shared and NTFS permissions are applied, the cumulative permissions of each are determined, and the most restrictive combination of those permissions create the user’s effective permission. </li></ul><ul><li>Offline files are available even when they are not connected to the network. All shared folders are available offline by default. Offline files are synchronized at logon and logoff by default. </li></ul>
