Name Resolution

Windows 2008/R2 and Windows 7 use three types of name resolution system:

1) Link Local Multicast Name Resolution (LLMNR)
2) NetBIOS
3) Domain Name System (DNS)

DNS is the preferred name resolution system in Windows networks and used whenever is available.

How to install and uninstall IPv6 on Windows XP

1. To install IPv6 on your Windows XP computer, follow these steps:
• Click Start, click All Programs, click Accessories, and then click Command Prompt.
• At the command prompt, type netsh int ipv6 install and press the Enter key on your keyboard.
• Close the Command Prompt window.

2. To uninstall IPv6 on your Windows XP computer, follow these steps:
• Click Start, click All Programs, click Accessories, and then click Command Prompt.
• At the command prompt, type: netsh int ipv6 uninstall and press the Enter key on your keyboard.
• Close the Command Prompt window and restart the computer.

IPv6 Address Types

IPv6 currently define three types of addresses:

•   Global Addresses:  IPv6 Global Addresses are the equivalent of public IP Addresses in IPv4.  An example of a global address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. Global Addresses are routable on the IPv6 Internet.

•   Link-Local Addresses: Link-local addresses are similar to APIPA address (169.254.0.0/16) in IPv4. An example of a global address is fe80::8ca1:3a64:a9b3:bc67%13. Link-Local Addresses  are not routable.

•   Unique Local Address:  Unique Local Address is the equivalent of the private addresses in IPv4 (10.0.0.0/8 – 172.16.0.0/12 – 192.168.0.0/16) An example of a Unique Local Address is fd00:dfba:9375:ffff::/12. Unique-Local Addresses are routable within a private network but not on the IPv6 Internet.

Exploring the Layers of the TCP/IP Networking Model

Configure a static IPv4 Address from a Command Prompt

To assign static IP address,default gateway and subnet mask, through command prompt on your Windows computer.

1) Start run: cmd
2) Type the command: netsh interface ip set address name="Local Area Connection" static 10.2.1.10 255.255.255.0 10.2.1.250

* Local Area Connection = LAN card interface name
* 10.2.1.10 = The static IP address we assigned to the interface
* 255.255.255.0 = The subnet mask
* 10.2.1.250 = The Default Gateway

Windows 7 Firewall Profiles

On windows 7 a firewall profile is a way of grouping settings, such as firewall rules and connection security rules, which are applied to the computer depending on where the computer is connected. On computers running this version of Windows, there are three profiles for Windows Firewall with Advanced Security:

Domain
Applied to a network adapter when it is connected to a network on which it can detect a domain controller of the domain to which the computer is joined.

Private
Applied to a network adapter when it is connected to a network that is identified by the user or administrator as a private network. A private network is one that is not connected directly to the Internet, but is behind some kind of security device, such as a network address translation (NAT) router or hardware firewall. For example, this could be a home network, or a business network that does not include a domain controller. The Private profile settings should be more restrictive than the Domain profile settings.

Public
Applied to a network adapter when it is connected to a public network such as those available in airports and coffee shops. When the profile is not set to Domain or Private, the default profile is Public. The Public profile settings should be the most restrictive because the computer is connected to a public network where the security cannot be controlled. For example, a program that accepts inbound connections from the Internet (like a file sharing program) may not work in the Public profile because the Windows Firewall default setting will block all inbound connections to programs that are not on the list of allowed programs.
 

Windows 7 choosing a network location..

The first time that you connect to a network, you must choose a network location. This automatically sets the appropriate firewall and security settings for the type of network that you connect to. If you connect to networks in different locations (for example, a network at your home, at a local coffee shop, or at work), choosing a network location can help ensure that your computer is always set to an appropriate security level.

There are four network locations:

• Choose Home network for home networks or when you know and trust the people and devices on the network. Computers on a home network can belong to a homegroup. Network discovery is turned on for home networks, which allows you to see other computers and devices on the network and allows other network users to see your computer.
• Choose Work network for small office or other workplace networks. Network discovery, which allows you to see other computers and devices on a network and allows other network users to see your computer, is on by default, but you can't create or join a homegroup.
• Choose Public network for networks in public places (such as coffee shops or airports). This location is designed to keep your computer from being visible to other computers around you and to help protect your computer from any malicious software from the Internet. HomeGroup is not available on public networks, and network discovery is turned off. You should also choose this option if you're connected directly to the Internet without using a router, or if you have a mobile broadband connection.
• The Domain network location is used for domain networks such as those at enterprise workplaces. This type of network location is controlled by your network administrator and can't be selected or changed.

Problem Steps Recorder

The Problem Steps Recorder in the Windows 7 operating system is a feature that enables users to record their interactions with an application and provide a detailed screen-by-screen view with accompanying information. Learn how the recording can be used to quickly identify problems and help reduce time spent with the help desk.
