A user complains that she cannot access files on a computer that was upgraded from Microsoft Windows NT 4.0 to Windows XP. All the data for the computer is stored on a separate partition from the operating sys tem. When Windows XP was installed, the data partition was left alone. The user s access problems are occurring for a folder called Client Data located on the root of the data partition. After doing some research, you find that the problem might be described in Knowl edge Base article 810881, Access is Denied Error Message When You Try to Open a Folder. Before you attempt to fix the user s problem, you have decided to try to re-create the folder on your own system to see how you will solve the problem on the user s system. Describe your solution.

Identify and troubleshoot problems with locally attached devices
Why This Matters
The purpose of this chapter is to teach you to resolve basic end-user calls involv ing devices that are attached to a computer. The chapter explains the different types of ports on a computer and shows how to troubleshoot basic problems that users of applications might encounter. This chapter also covers handheld devices such as personal digital assistants (PDAs), handheld computers, smart displays, and tablet PCs. Making these connections requires an understanding of the devices themselves, available connection types, and the software required by the devices. Advanced skills include understanding basic input/output system (BIOS) requirements and port requirements and troubleshooting BIOS settings when the connection is not functioning properly.

Resolving Issues with Locally Attached Devices
Lesson 1: Understanding Connection Types
As a desktop support technician (DST), you will often be approached by users who are having trouble with devices that are attached to their computer. From an application support standpoint, you may be faced with questions about why a user cannot print a doc ument, scan in an image, or get a handheld device to work. To support locally attached devices, it is important that you first understand how they are attached. This lesson intro duces you to the common connection types available on modern computers.
After this lesson, you will be able to
Identify the common ports available on most computers. Explain the use of each port type and identify the peripherals that use the port types. Identify common problems associated with each type of port.
Estimated lesson time: 15 minutes
Understanding Ports and Connectors
Every computer has several different types of ports available. Typically, ports are
accessed from the back of the computer, although some computers also have ports on
the front. These ports offer a place to connect portable devices such as printers, scan
ners, keyboards, and mice. The following are the six common types of ports that you
will work with:
Serial
Parallel
Universal serial bus (USB)
FireWire (IEEE 1394)
Infrared Data Association (IrDA)
