3.    Lab Work

Network File Sharing Exercises 

1.      Open My Network Places
      browse computers, identify icons (workgroup, entire network).

2.      Read Access Sharing: Connect to the shared My Documents Folder on instructor computer. 
  a) Open a file.
  b) Copy file from the shared My Documents folder to your local hard disk.
  c) Open the file in the sharedMy Documents folder through an application. 
      Attempt to save the file to the network folder (this will fail)

Write access sharing: Students create document with their own name on their desktops and copy it to shared folder on Instructor computer.

3.      Students examine My Network Places and verify that File and Printer Sharing is installed on their local computers.  (If already installed, may remove and reboot.)

4.      Students partner up.  Each student creates a shared folder on the desktop. with password protected full access.
 a) each student creates a document within their own folder with their own name and signs it.
 b) each student accesses the document on their partner's computer and signs in, resaving the document.

5.     Connecting to a shared printer:  each student connects to the shared Printer on the Instructor's workstation.  Attempt to print document.

6.      Creating a shared printer:  each student creates a shared printer on their own workstation.

  for information about NTFS File permissions.

  Suggested Homework

   Take this Windows XP Practice Test, compiled from A+ in Depth, Ch. 14 and Ch. 15.
Read A+ in Depth Chapters 17 (Supporting Modems), 18 (PCs on a Network), and 19 (PCs on the Internet)
   Answer review questions for each chapter and study the vocabulary terms.
   If you have time, also look at Chapter 21 (Supporting Printers) and 22 (All About SCSI).

   Continue working with A+ practice tests.
