CompTIA A+ 1102 Windows Networking

Shared Resources

- make a folder or printer available on the network

- share by mapping a drive letter to a share

- shares ending with a $ are hidden

- view shares in Administrative Tools/Computer Management

Mapping Drives

- needed to access a share on a remote device

- associates a drive letter with a share name

- view network shares in "This PC"

- create using "map network drive"

- or by using "net use [drive letter]: \\[server]\[name]" in command prompt

- disconnect a share in the toolbar or by right-clicking the drive

Sharing a Printer

- access the share function in printer properties, file explorer, or the settings application

- manage printer access under the security tab

Accessing a Shared Printer

add the printer to your system from file explorer or from the settings application

Proxy Settings

- a proxy seperates users from the internet

- access from settings > network and internet

- or control panel > internet options > connections > LAN settings

Network Locations

- determined automatically, but changeable in the network status menu

locations:

- private

- home or work network

- shares your device and allows for connections

- public

- provides no sharing or connectivity features

Network Paths

- viewable in file explorer, using the server name and the share name

Metered Connections

- managed under Network Settings

- set a data limit

- can modify application communication

Windows Defender Firewall

- integrated into Windows

- should always be turned on

- but, can temporarily disable from the main screen

- requires elevated permissions

- has different settings for each network type (public and private)

Windows Firewall Configuration Options (list)

- block all incoming connections

- ignores your exceptions

- the most secure option

- modify notifications

- app blocking

Firewall Options for an application

- block or allow by port number

- use predefined exceptions

- set custom rules

How Windows Systems get IP

With the DHCP, Windows can:

- provide automatic IP addressing, by default

- provides an APIPA if there's no static address assigned, and no DHCP server available

Automatic Private IP Addressing (acronym)

APIPA

Automatic Private IP Addressing (APIPA)

- allows for local communication only, hence the name, link-local address

- provides no internet connectivity

(APIPA) Range

169.254.1.0 to 169.254.254.255

TCP/IP Host Addresses are made of:

- IP address (unique identifier)

- subnet mask (identifies the subnet)

- gateway (the route off the subnet to the rest of the world)

What is the IPv4 loopback IP address?

127.0.0.1

IPv4 DHCP configuration location

- control panel > network and sharing center > change adapter settings

- then, right click an adapter and click the properties option

- lastly, left click the IPv4 settings and choose properties

Network Setup

- control panel > network and sharing center

- a step-by-step wizard to set up a new connection or a new network

- many different connection options

VPN Concentrators

- used to securely connect to private, corporate devices from a remote site

- utilizes a private tunnel from your device, to the VPN concentrator, and vice versa

VPN Connections

- Windows includes a built-in VPN client

- can integrate a smart card for MFA

- once set up, use the network status icon on the taskbar to enable or disable the VPN

Wireless Network Setup

provide (to the wizard):

- network name (SSID)

- security type (encryption method)

- encryption type

- TKIP, AES

- security key

SSID (acronym)

service set identifier

Wired Connections

- plug and play, direct connections

- the fastest connection is the default

- modify this in properties

- can also configure alternate connection, here

WWAN Connections

- built-in mobile technology

- USB connected or 802.11 wireless technology

- tethering/hotspots

- usually requires a hardware adapter and antenna connections

- as well as third-party software
