How do you configure a domain password expiration policy?
Configuring a Password Expiration Policy in Existing Domain (Change Password Policy Settings):
Open the Active Directory Users and Computers snap in while logged in to the domain controller as an administrator.
- Right-click the root domain name and select properties.
- Navigate to the Group Policy tab and choose "Edit" for the default policy
- Expand the policy folder: Windows Settings > Security Settings > Account Policies
Choose the Password Policy key, and change settings to as appropriate for your environment.
Go back up a level and then select the Account Lockout Policy key, and change settings as appropriate for your environment.
Your password change policy is now active in the domain, and will affect all user objects that are not set explicitly with "do not expire password".
A WORD OF CAUTION IN EXISTING DOMAINS: Keep in mind that once you enable the password expiration policy in an existing domain, you run the risk of immediately expiring all user passwords that have not been set with "do not expire password" on their account properties. This can cause a huge support nightmare. Before you enable the password expiration policy be sure to go through AD and set all staff user accounts with "do not expire password" under the "account" tab of the user properties. Then you can safely enable the above policies without affecting users.
Use a good pre planning and expiration reminder tool! Get something like Password Reminder PRO from SysOp Tools (http:/www.sysoptools.com) which will automatically send a reminder email to expiring password users and let them know when their password will expire, and will also allow you to clean up your AD before policy deployment. It is a great inexpensive tool that will save you a lot of work!
Use a good use support tool to reduce help desk load! The first two password change periods for users carry the highest support overhead as users get used to changing their password and creating a complex password. Any tools you can give them to make life easier will result in lower support calls and happier users / IT staff.
Typically, deploying an easily accessible web-based self service solution which allows users to self change password, self reset password or self unlock account is a great way to go. Look at something easy to deploy and inexpensive like Password Reset PRO from SysOp Tools.
Is IP address 172.32.1.100 public or private?
Private IP address ranges:
10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255
Definitely private =)
This is a Class B public address because the first octet ranges from 128 and 191.
Sorry! 172.16.50.100 falls in the category of private ip networks.

How does TCP and IP address works on networking?
TCP/IP is composed of layers, wherein each layer is responsible for performing certain operations on the data it receives and passing it to the higher layers. Each layer deals with certain issues related to the transmission of data and renders certain services to its higher layers.
The TCP/IP model consists of the link layer, the Internet layer, the transport layer and the application layer. Each layer consists of a set of protocols that function on the level of that layer. The link layer protocols are responsible for connecting the nodes in a network. The Internet layer consists of protocols, specifications and methods that are used to transport data packets across the network. The transport layer protocols deal with the transmission of data packets between source and destination network hosts. The application layer, the topmost layer in TCP/IP, directly interacts with application services. Thus, we see that TCP/IP functions at all the levels of communication between the components of a network. It is truly, the heart of network communication.
What type of networks are repeaters typically used?
Either a Bus topology or Wireless repeating, depends on how the question is stated...
What is the difference between routing and forwarding?
routing refers to deciding the route of the packet from one system (a computer) to another system (a computer). It involves many intermediate routers and routing table knowledge.
forwarding is a rather simple process of passing a packet from one port/interface to another port /interface. It generally involves one of the routers and routers forwarding table information
That's what they called call forwarding service in telecommunication.
How do you put a security Password on your wireless internet?
Your wireless network name, known as the SSID. This name identifies your network. You should choose something unique that none of your neighbors will be using. 2. Wireless encryption (WEP) or Wi-Fi Protected Access (WPA), which help protect your wireless network. For most routers, you will provide a passphrase that your router uses to generate several keys. Make sure your passphrase is unique and long (you don't need to memorize it). 3. Your administrative password, which controls your wireless network. Just like any other password, it should not be a word that you can find in the dictionary, and it should be a combination of letters, numbers, and symbols. Be sure you can remember this password, because you'll need it if you ever have to change your router's settings. The exact steps you follow to configure these settings will vary depending on the type of router you have. After each configuration setting, be sure to click Save Settings, Apply, or OK to save your changes.
How can server tell the difference between clients?
This depends on the architecture. This could be hardware or software dependent.
On some servers, clients are routed to different physical lines of data transmission. On other servers, clients are routed to different ports. On other servers, the clients send identifying information about themselves. This identifying information may be sent when a session is created, in the information packets themselves, or in the data wrappers.

How difficult is it to set up a home network?
It's extremely easy to set up a home wifi network, as all you need, is an internet connection and service, and then you need to purchase a wireless router.Most wireless routers are plug and play, so you don't need to install them or anything.
How do you communicate with other people using computer?
Telecommunication, or perhaps "e-communications". More specifically, there are several systems which allow for communications over the internet, such as VoIP (Voice over IP), e-mail and IRC. (Internet Relay Chat)
What is the function of transport layers?
It ensures that the Packet gets to its destination or it ensures packet delievry . If a packet fails to get its destination, it handles the process of notifying the sender.
Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the sub net mask and default gateway.

Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway. RFCs 2131 and 2132 define DHCP as an Internet Engineering Task Force (IETF) standard based on Bootstrap Protocol (BOOTP), a protocol with which DHCP shares many implementation details. DHCP allows hosts to obtain necessary TCP/IP configuration information from a DHCP server.
If you want to more further detail so you can visit this website:http://www.iyogibusiness.com DHCP (Dynamic Host Configuration Protocol) is a network protocol that enables a server to automatically assign an IP address to a computer.
Why was the TCP IP model developed?
The main theme of dividing the protocol into layers is to explain the rules of each layer specifically. This helps in putting various functions in separate modules and at the same time hiding the details of what they do and how they do it from other layers. This way we could improve the performance of one function or even change it all together, without having to change the whole protocol stack.
