Hamachi is a UDP-based virtual private networking system. Its peers are helped by a third node called a mediation server to locate each other and to bootstrap the connection between them. The connection itself is direct and, once established, no traffic flows through our servers.

Hamachi is not just truly peer-to-peer; it is verifiably secure peer-to-peer.

Hamachi is able to successfully mediate p2p connections in roughly 95% of all cases. This includes peers residing behind various firewalls or broadband routers (aka NAT devices).

Getting Started

If you have not already done so, you will need to download the LogMeIn Hamachi software.

The installation process is straightforward. Once setup has finished, Hamachi detects if you are running the program for the first time and will run a Quick Guide for new users to acquaint themselves with the program basics. By following this guide, you will be set up with a Hamachi address.

Creating a Network

Using Hamachi begins with the creation of a network. You do this by selecting the Networks button and then the Create new network option.

In the Create new network dialog box, you will need to name your network and create a password. The network name should be unique and is limited to 64 characters in length. The password – or pass phrase – should be something that only you know and is very hard to guess – the security of your network is dependent on it. There is no limit to the length of the passphrase. Once you have done this, click Create and non prescription cialis the network now appears in the Hamachi client.

Joining a Network

The next step is to have other computers join you network. On a computer other than the one used to create the network, click on the Networks button. In the menu that appears, select Join existing network.

The Quick Guide gives you an example network to join, however, in the above example, the name and passphrase of another network: MyPrivateNetwork, have been entered. The next step is to select Join. The network then appears in the Hamachi client, showing that you have joined it.

Leaving a Network

Leaving a network created by someone else is done by right clicking on a network in the client, and selecting Leave network.

Deleting a Network

If you wish to leave a network that you created the situation is significantly different. In this case, you are not leaving a network, but deleting it. Be careful with this option, as it will completely sever all connections between other members of that network and the action is irreversible.

It is done by right clicking on your network and selecting Delete network. Once you confirm the action, the network will disappear from your client and that of every other network peer.

Have you ever changed your desktop theme or just your desktop background and discovered that the text for your inexpensive cialis desktop icons is no longer transparent? Instead you now have a colored background box behind the text. If you have experienced this situation, chances are that you searched high and low for a solution, but were unable to find one.

Unfortunately, this is because the setting that allows you to control the icon transparency is very poorly named. Rather than being named something makes sense, Microsoft choose to name the setting “Use drop shadows for icon labels on the desktop.” To make matters worse, this setting is buried in the Performance Options dialog box rather than on the Display Properties dialog box.

In any case, sometimes that act of changing a desktop theme or desktop background inadvertently disables the Use drop shadows for icon labels on the desktop setting. Fortunately, re-enabling is it easy. Here’s how:

You should now have your transparent icons back.

Have you ever noticed that when you click a link in Internet Explorer, there is a distinct “clicking” sound that plays through your speakers? As if the actual click of the mouse button wasn’t realistic enough! If you’ve never heard that sound, you should consider yourself lucky, because by default, it is always activated. At first, it’s unnoticeable, but as you become more experienced with surfing the Web and you begin to follow links to your favorite Web sites, you will start to hear it more frequently. Luckily, there is an easy way to turn this sound effect off. Let's see how!

First, you need to find the Control Panel. In Windows XP, the Control Panel can be located right from the Start menu, as shown below. For Windows 95/98/Me/NT, click on the Start button, choose Settings generic cialis professional and then click on the Control Panel icon.

Once you have the Control Panel open, you'll need to search for the Audio properties. In Windows XP, you will find that under Sounds and Audio Devices, if you're in the Classic View. If you're in the Category View, you will first need to click on Sounds, Speech and Audio Devices, followed by Sounds and Audio Devices.
(To see whether you are in the Classic or Category view, simply refer to the first box in the blue column on the left hand side of the Control Panel window).

Below is a screenshot from the Windows XP Control Panel in the Classic View:

Here is one of the Windows XP Control Panel in the Category View:

For older computers, you can find the same settings by clicking on Sounds and Multimedia Properties or simply Sounds, depending on the version of Windows you're using.

Now, once you’ve clicked on the Sounds and Audio Devices icon, you will see the Sounds and Audio Devices Properties window. Across the top of that screen, you will see various tabs that can take you to different parts of the Properties area. Go ahead and click on the Sounds tab.

In the second half of the screen, you will see a scroll menu that lists all of the Windows sounds in different categories. Scroll down until you reach the Windows Explorer category and then click on the Start Navigation option.

When you click on the Start Navigation sound, a drop down menu will become available at the bottom of the window. This is where you can change the sound for each action. Click on the drop down arrow and a list of available sounds will appear. The one at the very top is the one we want. Find it and select [None].

Once you select [None], the last step is to click the OK button at the bottom.

Ah, silence sure is golden, isn’t it?!

Plug and play: I’m sure most of you have heard that term before, right? But, for those of you who don’t know exactly what it means, plug and play is a feature that allows a user to add a device to their computer, without having to reconfigure anything or install any manual drivers. A couple examples of plug and play devices are flash drives and MP3 players.

Okay, let’s say someone gave you a new MP3 player for Christmas and the box says its "plug and play!" So, you expect to plug it into the back of your computer and start transferring songs right away. Now, let’s say your computer does not recognize it. What do you do then? Well, let's defer throwing it against the wall for now and try some basic troubleshooting steps! The three most common ways to troubleshoot for devices like this are:

• Unplug the device and plug it back in.

• Restart your computer (with and without the device).

• See if an older device works. (For example, if you're trying to plug in a new MP3 player, try an old MP3 player. If you're using a new flash drive, try an old flash drive and so on).
