    NTP Server Operation

    A NTP server can operate in three modes: unicast; anycast and multicast. In unicast and anycast modes, the client transmits a NTP request message to the server. The server responds with a NTP time message that the client uses for time synchronisation. In multicast mode, NTP time messages are broadcast at periodic specified intervals.

    NTP Reference Clocks

    Primary NTP servers can synchronise with a number of external reference time sources. The GPS (Global Positioning System) is often used to provide an accurate timing reference. There is also a number of national time and frequency radio broadcasts available. The WWVB radio time broadcast is transmitted from Colorado and covers most of the US. The DCF-77 radio time signal is broadcast from Frankfurt, Germany, and covers much of central and Western Europe. The MSF radio time signal is broadcast from Rugby, UK, and covers the British Isles and much of Western Europe. Other local time and frequency radio broadcasts include: TDF, France, and CHU, Canada.

    NTP Versions

    The current release of NTP is version 4. The only significant modification to the protocol between versions 3 and 4 is a slight header re-interpretation to accommodate IPv6.

    SNTP Simple Network Time Protocol

    SNTP is a simplification of the Network Time Protocol, where the complexities of the full-blown protocol are not required. SNTP can be implemented when the high synchronisation performance of NTP is not required. The message format of the SNTP protocol is almost identical to that of the NTP protocol. However, the complex subroutines designed to maintain a highly accurate synchronised time are removed or simplified. Small computers with reduced processing power, such as micro-controllers or monitoring equipment most often use SNTP. The SNTP and NTP protocols are fully interchangeable, a SNTP client can synchronise to a NTP server without any issues.

    More Information: NTP RFC’s

    The original Network Time Protocol was introduced in RFC 958 (Request for Comments: 958). The full NTP version 3 protocol and synchronisation algorithms are described in RFC 1305. The SNTP version 4 protocols are described in RFC 2030.

    As the servers are used constantly, they generate tremendous heat. When this heat increases beyond control, it may lead to damage of the devices and equipment. Being machines, the computers are delicate under the hood and are prone to damage due to carelessness. System crashes, reboots, hang-ups, untimely failures; poor performance and other problems can be created due to abnormal temperatures. Now, one way to keep these issues under control is to maintain the server room’s temperature. Sufficient ventilation, cooling and maintained temperature are the efficient ways to protect computers and servers.

    Maintaining the temperature

    The computers used at homes and for small offices come with internal cooling devices, which usually keep the desktops and laptops cool. Nevertheless, the server rooms that manage a number of systems do not have sufficient internal cooling systems. They have to be kept cool using an external cooling source, such as portable air-conditioner. Secondly, increased humidity inside the enclosed area can cause corrosion or rust. The maximum humidity level of a server room should not exceed 40 to 50 percent.

    Are portable air conditioners good solutions for cooling?

    The temperature of the server room should be steadily cool around-the-clock. If the room or storage area is connected to the central cooling systems, they may be shut down during the weekends or sometime late at night, depending upon the company’s working hours. If the cooling systems fail, the computer systems are prone to face the brunt.

    Portable air-conditioners keep the server rooms cool, as the temperature can be controlled individually depending upon the outside temperature. There are few air-conditioners that adjust the temperature according to the outside temperature on certain modes. They are self-contained units which do not require permanent installation. Business owners can move these units anywhere as required.

    A portable AC used in such places must have condensation tank to manage the humidity level, automatic restart function and proper ventilation to replace the hot air inside the room. These features not only keep the servers cool but also regulate fresh air and keep the machines working continuously. The automatic function keeps the air conditioners working continuously even when there is a power cut or failure.

    When it comes to the size of the air conditioners it is never an issue. The server closet of size 9000 to 12000BTU will be sufficient for the unit to fit in. While a 12K BTU unit requires 9 to 12 amps a huge unit of 14000BTU requires 20 amps. The air-conditioner should be thoroughly checked for the necessary requirements before installation.

    Is your Internet Explorer (IE) running slow on Windows 7? Have you not tried the newest version called IE 9? Is your system not secured from viruses and spywares? If the answer to these questions is in affirmative you may give a thought to optimizing your system to make its performance better. Unfortunately slow speed in IE has been experienced by many people who have started using Windows 7.

    Undoubtedly slow performance of PC programs is intolerable. However, it is not just the IE browser that runs slow on Windows 7. Other browsers such as Opera, Chrome and Firefox have also been found to run slow due to various reasons. Sometimes users install Windows 7 in their old systems with low hardware specifications which causes such errors. At other times people who are fond of using too many add-ons in their browser suffer from slow browsing.

    If you are looking to speed up Internet Explorer for your Windows 7 follow these simple guidelines:

    * First of all clean computer up through a sophisticated Registry cleaning tool. The Registry repairing program will work to reduce Registry clutter and fix those errors which cause computer programs to crash frequently.

    * Optimize your system by managing computer services, conducting a Registry defrag scan and cleaning system and browsers junk through a good system utilities program. If you are an expert computer user you may do these jobs manually.

    * Go to the control panel settings and adjust ‘mouse’ settings. In the mouse settings Window click on the pointer options and make the pointer speed a little faster. This little act will give you a feel that your computer is running faster.

    * Clear the IE cache: Whenever you are about to quit browsing clear the internet explorer cache to make it lighter and run faster on Windows 7.

    * Clean temporary internet files and the IE history. A system utilities software can do this job automatically.

    * Get rid of excessive toolbars: Excessive toolbars and add-ons are often found to be not only making the browser slow but also causing it to crash frequently.

    * Disable integration with your download manager program. A download manager program usually integrates with your browser so that all downloads are cached automatically. However this causes Internet Explorer (IE) to run slow on Windows 7. Disable browser integration from the download manager program settings. Open download manager program, click Tools | Download Options. Click Browse Integration tab, uncheck Internet Explorer and click OK. Restart IE.

    * Uninstall Microsoft Java VM, which slows down Internet Explorer. Here’s how to do it- Click Start, point to All Programs | Accessories | Command Prompt. Type following command- “RunDLL32 ADVPack.dll,LaunchINF Section Java.in,UnInstall” (without quotes). Press ENTER. After successful uninstall, please restart your computer.

    Unit Command is an online military trading card game. The game involves multiple online players, each having a collection of trading cards that form the players army. Two players can play against each other to achieve a mission. The game has missions based in different terrains. Certain cards in the game are more powerful when used in certain terrains. Therefore a player must use the right cards in the right terrain for maximum impact. A card may represent an officer, a fighting unit, or reinforcement. The officer cards are the main cards, and unit cards and reinforcement cards are used for supporting officer cards.

    Players are allowed to trade cards with each other in this trading card game. This can be done using the Trade Zone feature of this game where a player can exchange a card from his/her collection with another player. Another way of procuring cards is to win in the game rounds. For each win, you get to choose a card from the opponents collection making your army strong, and rendering the opponents army weak. Yet another way of procuring cards is to purchase them from the in-game Store. You can procure desired trading cards in exchange of points from your account using the Store feature.

    While collecting these military trading cards from the Trade Zone, the Store, or the opponents collection, you must know your own collection first. Carefully assess what cards you have. As mentioned before, certain cards are more powerful in certain terrains. Choose officer cards with offense score as close to the missions defense score as possible. This will be achieved better if officers specializing in the missions terrain are selected, since in that scenario the additional offense of an officer is taken into account as well. See what kind of new cards your collection would require so that your army is ready for all kinds of terrains. For example, a player might have cards for jungle and tundra terrains, but may lack cards for desert terrains. Such a player must start collecting cards that would be more powerful in the desert terrain. While trading cards with other players, keep in mind the ratings of the cards involved. It would not be wise to exchange your highly rated card for an opponents low rated card. Grow your army so that its ready for all kinds of terrains.

    Unit Command is a mercenary trading card game brought to you by Wildcat Gaming, and can be played on www.unitcommand.com. The game requires no download, and is a free trading card game. This is a unique game with combined features of strategy games, war based games, role playing games and trading card games.

    Another new function is the Read-Only Domain Controller (RODC) that allows IT staff to configure the Active Directory infrastructure as read-only. Such a configuration keeps Active Directory replication unidirectional, rather than bidirectional, as it is normally configured. An organization could use this setup once again in the branch office location where connections back to the central office may not be as fast or as reliable. In this situation, Active Directory would be configured at the central office and then sent out to remote sites before it is accessed. Combining configurations of Server Core, BitLocker and RODC provides a level of security in the Server 2008 release impossible in prior releases. Configuring machines as read-only guarantees the data cannot be compromised even if a hacker were able to penetrate perimeter defenses. Also, if a theft were to occur in which a server was stolen at a remote site, BitLocker guarantees the data contained on the machine to be indecipherable, while RODC controls allow for administrators to reconfigure the network with a few clicks of the mouse.

    Internet Information Services (IIS) is the server-side technology that first became available with Windows NT 3.51 back in 1995. With the seventh full release of IIS available for the first time in Server 2008, the service becomes fully configurable. Web administrators specify precisely which services they would like to enable – and which services they would like to disable. All of IIS 7 is also supported by the new Server Manager console.

    Versions and Licensing

    Several different product editions of Windows Server 2008 are available. Depending upon the version, each type is configured for specific hardware platforms, such as 32 bit or 64 bit, and versions are available with virtualization capability built in, while others leave the function out.

    It is important to understand Microsoft’s different available methods of licensing when purchasing server products. The Microsoft Open License is intended for smaller customers with less than 250 desktop computers in their network. As few as five licenses can be purchased and with these licenses, the owner has the right to transfer images to different machines or transfer a license to another machine.

    Microsoft Volume Licensing is intended for networks serving more than 250 computers. Within this group are several account levels that offer flexible payment scheduling. The same rights are established as with the Open License, but there are added discounts for the volume purchases.

    Both types of licensing come with the option to add Microsoft’s Software Assurance plan, which provides maintenance for Microsoft products.

    Software Assurance includes comprehensive support including training and the ability to speak with Microsoft representatives to assist in deploying and managing Server 2008 software. Software Assurance should not be overlooked in any Microsoft purchase. With the purchase, software upgrades are included in addition to Version Rights, which guarantees the purchaser the right, at no extra charge, to new editions of the product purchased should one become available during the length of the Software Assurance contract.
