Windows Server is an operating system designed to help reduce common every day administrative operational tasks. There are a number of tasks, and one of them is data center power consumption. Due to the increasing number of computers in the data centers power consumption has become a problem, because of the amount of power supplied to them. Some Windows Server operating systems helps to reduce the amount of power supplied to the data center, therefore allowing more computers in the data center. File service management is another task that Windows Server provides that is not simple by any means, and it is also expensive to maintain. Windows Server will help companies manage data more efficiently and will also reduce costs. There are thirteen different editions of Windows Server with each having different features to them. However, four of these editions are more commonly used.

The first edition is Windows Web Server 2008, primarily used as a web server designed specifically for computers functioning as Internet or intranet Web servers and this edition will allow you to run on up to four servers. It will support 32 gigabytes of RAM on x64 hardware which is equivalent to Windows Server 2008 Standard edition. Windows Server 2008 Standard is limited as well, although it does have most of the full version's features. Windows Server 2008 Enterprise does have the full version of Windows Server 2008 and it supports Hyper-V and an unlimited number of network connections. Finally, there is Windows Server 2008 Datacenter the largest of the Windows Server editions and with little to no apparent limitations.

Although those editions have their advantages, as mentioned earlier they also have limitations. Windows Web Server 2008 cannot function as an Active Directory domain controller. The terms of the license for the software prohibit you from using this product as anything other than Web-based applications. Windows Server 2008 Standard has just a few more features than its Web-based counterpart. One of the main features it has is the Active Directory domain controller. The Standard edition will support only four processors with a maximum of 32 gigabytes of RAM on x64 hardware, in comparison to Windows Web Server 2008. This edition is primarily used by smaller businesses that do not require a larger server.

Windows Server 2008 Enterprise includes all of the Windows Server 2008 Standard editions features. Obviously this edition, like the other editions, will be more of an upgrade from the Windows Server 2003 edition. There are a few comparisons to Microsoft Windows Vista. They both share the same security features, there are a few other things that are going to take a network administrator some getting used to. Windows Server 2008 Enterprise, like Windows Vista, the Run feature is not on Start menu. This edition of Windows Server 2008 will support up to eight processors, an unlimited number of network connections and 2 terabyte of RAM on x64 hardware.

Finally, Windows Server 2008 Datacenter is designed for large and powerful servers and can only be purchased from original equipment manufacturers, bundled with a server. This edition is intended for large corporations with numerous employees and clients. It supports up to 64 processors and 2 terabytes of RAM on x64 hardware. It has all the features as the other editions, therefore, no apparent feature limitations. Datacenter is the high-end costly edition and is almost 100% reliable. However, most businesses will probably purchase the least expensive Standard or Enterprise edition to keep costs down.

There are other server operating systems that might be less complicated and less expensive to a company than the Windows Server editions. Microsoft and Linux users are obviously bias, when comparing the them vs. us theory. One thing a lot of businesses like about Linux Server in comparison to Microsoft Server editions is that Linux is open source, meaning it's not as costly as their Microsoft counterpart if it cost anything at all. Linux is mostly used in Web server applications; however it is becoming more common in mission critical applications. Microsoft leads this race in revenues, but Linux is not far behind, however the comparison is uneven or hard to compare, because Linux is mostly provided at little or no cost. This race is so close that Microsoft and Red Hat have an agreement to allow each other to run on virtual platforms, meaning Linux can run Windows Server on a virtual machine and Windows can run Linux Server on a virtual machine. When comparing the two server applications, Windows and Linux both are still in high demand.

Windows Server is a little more user friendly than Linux because it uses graphical user interface whereas Linux is mostly command driven. Some companies use both Linux and Windows Servers because it allows them flexibility. It has become apparent in some instances within these organizations that Windows Server and Linux Server both rely on each other to function properly. Linux does not have the technical support available that Windows does in most cases because it is open end, which keeps most businesses from using it.

Active Directory primary functions are authentication and authorization, which verifies a user's identity and grants users access to resources they are allowed to use. When a user joins an Active Directory they log into the domain they have been granted access to. If a user attempts access and has not been granted access to any resource on the network by the administrator through the Active Directory, access will be denied. Whenever a user logs on, using a password, the client computer locates the nearest domain controller and exchanges a series of messages. Active Directory networks can also use smart cards or fingerprint scans to verify a user's identity.

An Active Directory domain has advantages. Users would have no need to have separate accounts on every computer they would log on to. Therefore making it easier to remember passwords or maintain accounts on each computer. Active Directory also allows the user to perform multiple logons. . Active Directory can accommodate either a small or a large organization and provide several design options. It can divide and populate organizational units to allow flexibility within the organization.
