Fix for Messenger webcam problem

Fix for Messenger webcam problems

A workaround has been released for installing your webcam with Windows Live Messenger.

The following message was recently circulated by the Windows Live team in response to an issue that some users were experiencing. Follow the advice below to clear up any issues caused by installing the new version of Messenger.

“We’ve heard that a small number of you are experiencing audio and video problems with your webcam after installing the latest version of Windows Live Messenger. After looking into this, we found that for users who are seeing error code 0x8AC70013 or 0x8AC70202, this may be caused by an incompatibility with McAfee Site Advisor.

McAfee is working on a patch to fix this, but until it becomes available, if you’re having audio or video problems with the new version of Messenger and are running McAfee, McAfee has posted a workaround on its website."

Subnet a Network Basic Steps

A properly designed subnet can do wonders for the security and performance of a network. The main idea in subnetting is to divide a network into smaller pieces, which we call subnets. Actually implementing a subnet is typically more difficult than simply using the default subnet mask of 255.255.255.0. This usually means that temporary or smaller networks do not need to be subnetted.

Security sees benefit since the IP addresses of the host computers on each subnet are masked by the network address- which means they are invisible to the outside world. We call this network address translation, or NAT. This same technique helps conserve IP addresses, since all hosts on the subnet essentially just use the network IP address during communication.

A Basic Review on Subnetting

If you’re a little rusty on the basics of subnetting, don’t worry. We’ll cover everything you need to know from beginning to end. First thing first: we need to learn about the IP basics.

The current version of internet protocol, or IP, is IP version 4. This IP version allows four octets of data to represent an IP address. Each octet is considered to be a byte, so there are 8 bits in every octet. Note that in binary form you can see that there are 8 numbers, each one consisting of a bit. Finally, each octet is separated by a period, as shown below.

Each IP address is usually represented in decimal form, as seen above as “192.168.2.1”. However, each IP address is actually used by computers in binary form. You may have noticed a huge flaw in IP version 4: the amount of unique IP addresses is limited! To be exact, only 4,294,967,296 unique IP addresses can be created. This may seem like a large number but keep in mind every single device in the world needs a unique IP address to communicate with one another while online.

The IP version 6 protocol was created for when the transition is needed. Most computers don’t use IPv6 just yet, but in the future it will inevitably be used. (In case you were wondering, IPv6 will support 2^128 unique IP addresses… egad!)

Classes

There are three main types of classifications of IP addresses in IPv4: class A, class B, and class C. There are class D and class E types, but those are for multicasting and private uses, respectively. Each class differs by the number of network and host octets it has. Each network octet is for classifying which network a host is on. More network octets will mean more networks! Likewise, each host octet specifies a host that can be assigned to the network. More host octets means more computers per network.

Each class has a certain range that the first octet can be assigned to. This lets us know to what network class any IP belongs to with ease. Review the diagram below to see a visual diagram.

Now the bad news: you must memorize each range for each class if you hope to pass most network exams. Don’t worry! It’s actually easy- just memorize how we get the numbers, not the numbers themselves! All you have to do is remember n^8 (read as “n” to the eighth power), and how many network portions each class has. Review the diagram below.

One final note before we move on. Notice how we didn’t use the IP address 127 for the class A network- that’s because this is loopback address. We use this for testing configurations on the IP network. Also take note that there are reserved IP addresses, such as those for private networks. These IP addresses will not connect to the internet, which is handy if you just want computers to be connected with each other- and not the whole world.

Subnet Masks

A subnet mask is what we use to assign different amounts of networks and hosts to an IP network. It essentially divides the IP address into two parts: the network and host. This is a trading game- the more hosts you have, the fewer networks you will have. And yet the more networks you have, the fewer hosts you will have. Review the class A default subnet masks as shown below.

The class B network will need to recognize two network portions, and two host portions. This can be seen in the below diagram.

Lastly, we have the class C subnet. It is the most commonly used subnet, so pay special attention to it in the upcoming lecture. You can see a diagram of the default subnet below.

We’ve laid Down the Foundation, Let’s Build the House!

We just reviewed the basics of IP addresses and subnet masks. The bad news is, we usually don’t use the default subnet mask at all when we subnet a network! The good news is, learning how to subnet isn’t too hard. It will, however, take some practice.

An Example of Subnetting a Class C Network

Subnetting varies in difficulty, depending on which class you are subnetting. More often than not, you will need to create a subnet for a class C network. A class C network allows for many networks to be created, but not as many hosts. In fact, you can create a hefty 2,097,152 networks- but only 254 hosts per network are allowed.

Let’s say we are subnetting a school’s network. We need 5 separate networks that have 30 computers on each subnet.

First we calculate how many usable subnets we need. Next we will need to determine how many hosts are required. Both of these values can be calculated with the following equations:

Two Important Equations to Remember:

---

• 1. Usable Subnets = (2^n) – 2 , where N = power of bits assigned
• 2. Usable Hosts = (2^n) – 2 , where N = power of bits remaining

Let’s start with usable subnets. Review the diagram below for a visual example.

If you are wondering what the “-2” part of the equation is for, this is how we account for the two addresses in each subnet we can’t use. We will review what these addresses are for more specifically later on. For now, let’s find out what our usable hosts are!

Alright Already! What’s My Subnet Mask?!

Getting your subnet mask at this point is incredibly easy. Simply take all of your network bits, and add them up. Look at the diagram below for a visual guide.

That’s it! You’re done. You have successfully created a subnet mask that can be used on the school’s network. Keep in mind that every computer must have the subnet mask set in order for them to be on the same network. Also note that since we are using a class C network, the first three octets will always be 255. When subnetting other classes, be sure to keep the network portions in mind.
