The desktop policies must be set to allow access to the Display icon in control panel. The following resources will be required: 1. PC workstation with monitor, keyboard, mouse, and power cords 2. Windows operating system (Windows 9x or XP) installed on PC Step 1 – Boot (start) the PC and log on. Step 2 – Use the Control Panel / Display to change the monitor’s display settings (This may also be accomplished by right clicking the desktop and select Properties) • Select the Setting tab. Record your findings in the table below: Current Display Current Resolution Current Color Depth What screen resolutions are available? What color depths are available? • Change the screen resolutions. How does it effect the display? • Change the color depth. How does it effect the display? • Reset the resolution and color depth back to their original settings. Step 3 – Select the Advanced button to see more options. • What is the current DPI? IT: Computer Maintenance: Monitors Plan Copyright © Texas Education Agency, 2011. All rights reserved. 5 • Change it. How does it effect the display? • Reset the DPI back to its original setting. Step 4 – Record information about the adaptor: Chip Type DAC Type Memory size BIOS Screen Refresh Rate • Select Cancel to return to the Display Properties main screen. Step 5 – Check the monitors power settings by clicking on the Screen Savers tab. • Is the computer Energy Star Compliant? • If you see the Energy Star Logo and the Power button is enabled, then the computer is energy Star Compliant. The Energy Star label, a symbol for energy efficiency, was created by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) to help customers identify products that can save them money and protect the environment by saving energy. An ENERGY STAR qualified monitor, in sleep mode, uses 90% less electricity than monitors without power management features. • Click on the power button. Record information about the current power setting scheme: Turn monitor off Turn off hard disks System standby Is Hibernate turn on?

The desktop policies must be set to allow access to the Network icon in control panel and either the Run Command or the DOS Command Prompt in order to run the WINIPCFG and IPCONFIG utilities. The following resources will be required: 1. PC workstation with monitor, keyboard, mouse, and power cords 2. Windows operating system (Windows 9x or XP) installed on PC 3. NIC installed and Cat 5 patch cable with connection to the Internet Windows 9x (use this procedure if you are using a Windows 9x machine) Step 1 – Boot (start) the PC and log in to the network. Step 2 – Use Control Panel / Network to determine the Workstation Computer name, Domain name, Network Client, the network layer 3 protocols in use, and information about the NIC. (You may also right click Network Neighborhood and select Properties) • Click the Identification Tab at the top of the window to find the Computer name and the Workgroup. • Click the Configuration Tab and note what networking components are installed. The Network Client has an icon that looks like a computer, the NIC icon looks like a NIC and the Protocols have an icon that looks like a network cable connection. There may be more than one of each of these. Record your findings in the table below. Component (NetBIOS) Name NT Domain Name Network Client Type NIC installed (driver name) 1st Protocol installed 2nd Protocol installed Other network components Other network components Step 3 – Check the TCP/IP related settings such IP address information, DHCP and DNS. • Click on the TCP/IP protocol while on the Network Configuration Tab and then click Properties. Click on the Tab indicated in the table and record your findings below. IT: Computer Maintenance: Monitors Plan Copyright © Texas Education Agency, 2011. All rights reserved. 7 TAB IP Addr. Type of Information How does the workstation get its IP Address IP Addr. Workstation IP Address IP Addr. Workstation Subnet Mask Gateway Default Gateway DNS Cfg. Is DNS enabled? DNS Cfg. DNS Server IP Address WINS Cfg. Is WINS enabled? WINS Cfg. WINS Server IP Address Findings Step – 4 Using WINIPCFG.EXE utility • You can run WINIPCFG.EXE from the Start / Run command or from the DOS command prompt. (If you enter WINIPCFG /ALL from the command line (be sure to put a space between WINIPCFG and /ALL) you will get much more information.) • Be sure to select the proper NIC or Ethernet adapter (this will be in a pull-down box). Record your findings in the table below. Workstation IP Address Workstation Subnet Mask Workstation MAC Address Default Gateway (Router) DHCP Server DNS Server IP Address WINS Server IP Address Windows XP (use this procedure if you are using a Windows XP machine) Step 1 – Boot (start) the PC and log in to the network. Be sure you have administrative rights to view the TCP/IP settings. Step 2 – Use Control Panel / System to determine the Workstation Computer name and Workgroup/Domain name. (You may also right click My Computer and select Properties) • Click the Identification Tab at the top of the window to find the Computer name and the Workgroup/Domain name. • Click the Configuration Tab and note what networking components are installed. The Network Client has an icon that looks like a computer, the NIC icon looks like a NIC and the Protocols have an icon that looks like a network cable connection. There may be more than one of each of these. Record your findings in the table below. Full Computer Name Workgroup or Domain Name Computer Description IT: Computer Maintenance: Monitors Plan Copyright © Texas Education Agency, 2011.

(You can also right click My Network Places then Properties to open the Network connection window) • If your workstation obtains its IP address automatically (a DHCP client) you must use the IPCONFIG utility to determine its IP address and subnet mask. Type of Information How does the workstation get its IP Address Findings Workstation IP Address Workstation Subnet Mask Default Gateway Is DNS enabled? DNS Server IP Address Is WINS enabled? WINS Server IP Address Is the Windows Firewall enabled? Step – 4 Using IPCONFIG.EXE utility • You must run IPCONFIG.EXE from the DOS command prompt. (If you enter IPCONFIG /ALL from the command line (be sure to put a space between IPCONFIG and /ALL) you will get much more information.) • You will see all active adaptors listed. Record your findings in the table below. Host Name IP Routing enabled? WINS Proxy enabled? Adaptor Name Workstation IP Address Workstation Subnet Mask Workstation MAC Address Default Gateway (Router) DHCP Server DNS Server IP Address WINS Server IP Address Lease Obtained Lease Expires Is there more than one adaptor?
