Microsoft Exchange Server is part of the Microsoft Windows Server line, and is intended to deliver a platform for messaging and collaboration. The primary features of Exchange Server include email, calendaring, contacts and tasks. Exchange Server also provides a platform for mobile and web-based users who need to be able to access their data remotely, as well as support for data storage.
Enhanced Features
Microsoft Exchange Server was first launched in 1996; more recent versions, such as Exchange Server 2007 and recently released Exchange Server 2010, include many enhancements from its original version. Some of these are:
Security: Exchange Server now includes anti-spam and anti-virus filtering, as well as encryption technology. This protects users' data from outside intrusion and corruption.
Data Protection: Exchange Servers can be used in a cluster environment, which replicates the data across several servers and guarantees its availability. In this way, there can be no single point of failure; if one server goes down, the other servers will pick up the slack and continue to provide data to users.
Unified Messaging: Exchange Server allows users to receive voice mail, email, and faxes in their mailboxes. In addition, remote users can access their mailboxes from cell phones and other wireless devices.
Improved IT Experience: Exchange Servers are completely scalable, and include 64-bit performance. There is a simplified graphical user interface (GUI) to make administration easy, and an improved deployment and routing process.
Exchange Server Roles
As a network administrator, you can choose which server roles to install on an Exchange server. Server roles are used to logically group specific features of Exchange together, which helps to simplify installation, and gives you the ability to fully customize your Exchange Server to meet your company's specific needs.The types of server roles include:
Mailbox Server: This server runs on the back end, and hosts mailboxes and public folders.
Unified Messaging Server: This is the middle-tier server that connects a Private Branch Exchange system (PBX, commonly referred to as a phone system) to Exchange 2007.
Client Access Server: This is the middle-tier server that hosts all client protocols, such as Secure Hypertext Transfer Protocol (HTTPS), Post Office Protocol 3 (POP3), Internet Message Access Protocol 4 (IMAP4), and Outlook Anywhere. The Client Access Server can also host Web services.
Hub Transport Server: This server is responsible for routing all mail within the Exchange organization.
Edge Transport Server: This server typically sits on the perimeter of the network topology, and is responsible for routing mail into and out of the Exchange organization.
For the End User
Clients that are using Exchange Server to access their data will typically use Microsoft Outlook, part of the Microsoft Office suite. However, there are alternatives. If a client wishes to connect to their email through a website, they can use Outlook Web Access (OWA). And for Mac users, both Microsoft Entourage and Apple Mail can be used to connect to an Exchange Server.

How to Become a TV Show HostIn Feburary 2016 20,
In Feburary 2016 20,
As with most jobs, a degree is the ticket you need for employers to take you seriously. While there are no degrees in television hosting, some degrees will be more helpful than others. Top choices include degrees in communications and journalism, while other helpful ones can be drama, media or social sciences. Make sure you have some coursework in public speaking. Depending on the type of host you want to be, you may need specialized knowledge such as history, political science or natural science.
Hard and Soft Skills
TV show hosts need a combination of soft skills and technical skills. Soft skills include self-confidence, a clear voice, interpersonal skills, improvisation skills, the ability to work calmly under stress, the ability to think and speak quickly. You adapt to new information as soon as it presents itself. You are prepared for surprises and can continue to talk even while processing. Your curious mind is supported by verbal mastery of such skills as listening, leading conversations and being able to ask incisive questions. You also need to have teaching skills, as you will be teaching your audience while leading guests through their topic of expertise. Technical skills include a basic knowledge of television terminology and operating procedures, the ability to keep presenting while hearing instructions through an ear piece, working with a teleprompter and the ability to operate sound and video equipment.
Genuinely You
Part of what you need can't be learned in school or on the job: You have to be you and you have to have a great personality. 'To be a good host, you need to be very comfortable in your own skin,' said television host Suzanne Sena, quoted in a Backstage.com article. 'It's vital that you feel confident and comfortable, so that you can then make your audience or on-camera guests feel comfortable as well. They will feed off your energy -- or die by it.' She recommends having a natural curiosity and a genuine interest in talking to people. You need to express your personality through your language skills, such as pronunciation and enunciation, and through the way you move. Use your whole body to communicate.
No Substitute for Experience
Television hosting is a competitive field and you're not going to get in without some experience. Start by building a network of contacts through media and broadcast associations. Offer to host as a volunteer for non-profit organizations that are having television broadcasts for fundraisers or other events. Volunteer for community cable or educational shows to gain experience. Many local access stations will accept non-profit shows that you could host. Apply for internships at television stations, especially local ones. Make a newsreel of yourself that is two to three minutes long and shows your hosting skills and personality. Send this newsreel on CD, DVD or via email to broadcasters, producers and agents. Another option is to work your way up by getting another job at a television studio and letting your boss know what your career goals are.

How to Disable Sites in Apache 2In Feburary 2016 09,
In Feburary 2016 09,
Verify that the site is still enabled. From the Ubuntu Linux command line, issue the following commands:cd \etc\apache2\sites-enabledlsThe first command switches the working directory to the 'sites-enabled' sub-directory. The second command lists the files in the directory. If there is a file for the site you want to disable, continue with Step 2. If not, the site already is disabled.
Issue the following commands at the Ubuntu command prompt:cd (changes to your home directory)sudo a2dissite sitename (where 'sitename' is the name of the site you want to disable) This command removes 'sitename' from the /etc/apache2/sites-available sub-directory.
Verify that the site has been removed from the list of enabled sites with the following command:ls /etc/apache2/sites-enabledYour site should not appear in the sub-directory listing.
Restart the Apache 2 Web server with the following command:sudo /etc/init.d/apache2 restartThis causes Apache 2 to stop listening for requests for the disabled site.
Start a browser session and attempt to navigate to the site. If your site is disabled, you should get a 'Not Found' message on a default error page.
