    Windows Network Diagnostics
  2. How can you start Windows Network Diagnostics?
    • In the system tray, right-click the network icon and click Troublshoot Prolems.
    • Open Network and Sharing Center. On the Network Map, click the link with an X over it.
    • Open Network and Sharing Center. Near the bottom of the right pane, click the Troubleshoot Problems link.
    • From the Network Connections page in Control Panel, right-click a network adapter and then click Diagnose.
    • When Windows Internet Explorer is unable to access a Web site, click the Diagnose Connection Problems link.
    • Enter "rundll32.exe ndfapi,NdfRunDllDiagnoseIncident" (case sensative) in the Run command.
  3. Where does Windows Network Troubleshooting store detailed information about the troubleshooting process?
    Event Viewer > Windows Logs > System
  4. What command-line tool is most commanly used to begin diagnosing networking problems in Windows?
    ipconfig
  5. What is the command to get ipconfig to list detailed information about all network connections?
    ipconfig /all
  6. What command(s) can be used with ipconfig to renew an:

    ipv4 address?
    ipv6 address?
    • ipconfig /release
    • ipconfig /renew

    • ipconfig /release6
    • ipconfig /renew6
  7. What is the best known command-line network diagnostic tool?
    Ping
  8. Why is Ping less useful today than in the past?
    More and more computers and routers are blocking Internet Control Message Protocol (ICMP) requests. Ping still works on most local LANS.
  9. What are the two main things that Ping can tell you?
    • Whether or not a host is online and
    • The time, in milliseconds, indicating the round trip latency.
  10. What is PathPing used for?
    Although Ping uses ICMP to test connectivity to a specific host, PathPing uses ICMP to test connectivity to a remote host and all routers between you and the remote host.

    PathPing is a more powerful replacement for Tracert.
  11. What is PortQry used for?
    PortQry tests whether a specific network service is running on a server.

    • Example: "portqry -n www.microsoft.com -e 80"
    • This tests port 80 at www.microsoft.com to see if web services are available.
  12. Is PortQry included with Windows?
    No, portqry is not included with any version of Windows but can be downloaded from Microsoft.
  13. What tool can be used to test whether your DNS server can properly resolve a host name to an IP address?
    NSLOOKUP
  14. What does APIPA stand for?
    Automatic Private IP Addressing
  15. When would a computer get an APIPA assigned IP address?
    When the computer is configured to use automatic IP addressign but is unable to contact a DHCP server.
  16. What address range can be assigned by APIPA?
    169.254.0.0 thru 169.254.255.255
  17. Connectivity problems can be broken down into what two categories?
    • Network connectivity problems and

    Transmission Control Protocol (TCP) port 143
  22. What port does the following Service Name or Task use?

    Network And Sharing Center
  33. What does "netsh" stand for?
    network shell
  34. What command line tool can be used to manage wireless network connections?
    netsh wlan

    • Examples:

  35. Where would you go in Windows to reconfigure an existing wireless connection?
    Network and Sharing Center > Manage Wireless Networks
  36. Where would you go in Windows to change the priority order for wireless networks?
    Network and Sharing Center > Manage Wireless Networks > select a wireless network profile and then click Move Up or Move Down.
  37. Name five types of network security.
    • No security
    • Wired Equivalent Protection (WEP)
    • Wi-Fi Protected Access (WPA)
    • ...............WPA-PSK (Pre-Share Key - also known as WPA Personal)
    • ...............WPA-EAP (Extensible Authentication Protocol - also known as WPA Enterprise)
    • WPA2
    • Open with 802.1X
  38. What is the most secure wireless security method?
    WPA2-EAP
  39. What are three way that WPA-EAP can authenticate users?
    • PEAP-MS-CHAPv2 to enable users to connect to a wireless network using their domain credentials.
    • Certificates stored on the user's computers
    • Certificates stored on smart cards
  40. What does RADIUS stand for?
    In Windows Server 2008, what service acts as a RADIUS server?
    • Remote Authentication Dial In User Service (Radius)
    • Network Policy Server (NPS)
  41. What process (steps) does a client go through to connect to a WPA-EAP wireless network?
    Whichever authentication method you choose, Windows uses the same authentication process.

    The wireless client computer passes the credentials to the wireless access point, which forwards them to a RADIUS server, which then authenticates the user against AD DS.

  42. What is the default authentication method Windows 7 uses when connecting to a new WPA-EAP or WPA2-EAP network?
    Secure Password (EAP-MSCHAP v2)
  43. Name the two types of wireless network profiles
    • All-user profiles and
    • Per-user profiles

    Most mobile computers are used by only a single user. However, if mobile computers inyour organization are shared between multiple users, you might want to configure wirelessnetworks to use per-user profiles. With per-user profiles, one user can connect to a wirelessnetwork without other users being able to use the same wireless network connection.
