3. What is Internet Protocol Version 6 (TCP/IP)?

IPv6 was introduced first with Windows XP and Windows 2003 to expand on IPv4 to get past the limitation of a maximum of 4 Billion IP addresses using the old 32 bit system. IPv6 now uses a much longer IP address using Hexadecimal numbers. Windows will automatically assign an IPv6 address when you configure your normal IPv4 address. Here is an example of an IPv6 address:
fe80::4490:9230:7194:a69b. You can view the IPv6 address by clicking on Details on the network connection properties or use the IPConfig tool.

4. How do I enable or configure Windows Firewall?

The Firewall in Windows can block outgoing and incoming traffic to your computer. To configue it, goto Start, Control Panel, Network and Internet, Windows Firewall. You can add or remove programs allowed through the Firewall by selecting Allow an app or feature through Windows Firewall:

Firewall apps

Click on Change settings and then Add another app and select the program from the list or Browse for the program on the hard disk. If you have uninstalled a program, use the Remove button to remove the program from the Exception list. If you want to allow specific protocols or ports then use the Advanced Settings instead, this will load the Windows Firewall with Advanced Security window.

Open the Local Security Policy console in Administrative Tools, expand Local Policies, Security Options and look for Network Security:
LAN Manager authentication level
. Change the option from Send NTLMv2 response only to Send LM & NTLM - use NTLMv2 session

b) File and Print Sharing for Microsoft Networks. Required for access file shares and shared printers between PCs and servers.
c) QoS Packet Scheduler. Ensures Quality of Services for certain data packets over network esp. video and audio traffic.
d) Internet Protocol Version 4 (TCP/IPv4). This enables access to services over the internet using Transport Control Protocol/Internet Protocol using 32-bit number system e.g.
e) Link-Layer Topology Discovery Mapper (LLDP). Discovers other devices connect to the network such as other PCs, routers, NAS drives etc (see Network icon in Explorer).
f) Microsoft Network Adapter Multiplexor Protocol. Use for NIC teaming and binding for load balancing network traffic with two or more network adapters.
g) Microsoft LLDP Protocol Driver. Uses the Link-Layer Discovery Protocol for discovery other devices on the network.
h) Internet Protocol Version 6 (TCP/IPv6). This enables access to services over the internet using Transport Control Protocol/Internet Protocol using 128-bit number system.
i) Link-Layer Topology Discovery Responder. Responds to other devices searching for devices on the network.
j) Link-Layer Topology Discovery Mapper I/O Driver. Used to discover and locate other PCs and devices on the network.

11. How do I connect to a Virtual Private Network (VPN)?

A Virtual Private Network (VPN) is an additional network on top of your normal local network which has a secure connection to your work place's network via their firewall or VPN server.
This basically means that when you connect to the VPN network, your computer is now part of your work place's network and allow access to services and resources inside that network that are
not normally accessible over normal internet connections. Since the connection is secure, any network traffic is automatically encrypted, so data is not readable by third parties.
To connect to a VPN you need a VPN client. You should always use the client software that your work place recommends and/or provides for you.

In Windows, you can use the Network and Sharing Control Panel to set up a VPN connection to your work place. Open Control Panel, select Network and Sharing Centre,
select 'Setup a new connection or network' , then 'Connect to a workplace'.

Select type of connection: via internet or via a phone number, and if internet, enter a internet address of VPN service or a telephone number (you need a dial up modem for this).

12. How do I communicate to someone over the internet?

There are many clients available that allow you to talk and view another person over the internet using a Webcam and a headset with ear phones and a microphone.
a) Classic Skype client (see Microsoft Store)
b) Client such as Skype for Business for workplace communication.
c) Microsoft Teams for Office 365 users.
d) Zoom client.
e) GotoMeeting client.

13. How do I access services via a standard desktop interface?

Remote desktop services allow you to provide a standard desktop or a suite of applications that can be access remotely via the web interface or a client.
Microsoft's remote desktop services provides either Session-based virtualization using Windows server or Virtual Desktop Infrastructure (VDI) to ensure high
performance and maximum application compatibility for running important applications. Usually RDS is accessible via a web interface e.g. https://rds-address/rdweb
or a client.

Alternatives or in addition to RDS, you can use other solutions such as Parallels Remote Application Server (RAS), or Citrix Virtual Apps and Desktops, and
Amazon Workspaces.

To login to other Windows compuer you will need to use the Microsoft Remote Desktop Connection software. You can then connect to any Windows desktop
or server on your local network or over a VPN connection.
