Introduction

Windows Server is a powerful and versatile platform developed by Microsoft and part of the server operating systems family. It is designed for businesses to manage their infrastructure, run applications, share resources, and ensure security. This article aims to provide a wide range of information about Windows Server, from installation to management, best practices, and troubleshooting methods. Whether you are a novice system administrator or an experienced professional, this article will provide you with the tools and information you need to optimize and efficiently manage your Windows Server environment.

1. Windows Server Editions and Licensing

1.1. Differences Between Editions

Windows Server is available in various editions to suit different needs and budgets. The most common editions are:

• Windows Server Standard: Suitable for small and medium-sized businesses. It offers basic server functions and limited virtualization capabilities.
• Windows Server Datacenter: Designed for large enterprises and data centers. It offers high scalability, advanced virtualization, and cloud features.
• Windows Server Essentials: An easy-to-use and affordable solution designed for small businesses.
• Windows Server Hyper-V Server: A free edition optimized for virtualization only.

The following table compares the key features of different Windows Server editions:

1.2. Licensing Models

Windows Server licensing consists of two main components: core-based and CAL (Client Access License). Core licenses are determined by the number of physical cores in the server. CALs are required for each user or device accessing the server.

• Core Licensing: A license must be purchased for each physical core. The minimum number of core licenses is 16 per server.
• CAL (Client Access License): A separate CAL is required for each user or device accessing the server. There are two types of CALs: User CAL (per user) and Device CAL (per device).

1.3. Licensing Best Practices

• Choose the right version: Selecting the version that best suits your business needs helps you avoid unnecessary costs.
• Track licenses correctly: Regularly tracking your licenses helps you avoid compliance issues.
• Optimize virtualization: By using virtualization, you can use your hardware resources more efficiently and reduce your licensing costs.

2. Windows Server Installation

2.1. Hardware Requirements

Before installing Windows Server, make sure your server meets the minimum hardware requirements. The requirements may vary depending on the version you are installing and the role of the server. In general, the following requirements should be considered:

• Processor: At least 1.4 GHz 64-bit processor
• RAM: At least 2 GB RAM (4 GB recommended for installation with GUI)
• Disk Space: At least 32 GB disk space
• Network Adapter: Gigabit Ethernet adapter

2.2. Installation Steps

Follow these steps to install Windows Server:

1. Insert the installation media (DVD or USB) into your server and start the server.
2. Change the boot order in the BIOS settings to boot from the installation media.
3. The Windows Setup wizard will start. Configure the language, time, and keyboard settings and click "Next".
4. Click "Install Now".
5. Accept the license terms and click "Next".
6. Select the installation type: "Custom: Install Windows only (advanced)".
7. Select your disk and click "Next".
8. The installation will begin. This process may take several minutes.
9. After the installation is complete, the server will restart.
10. Create an administrator password and log in.

2.3. Server Core Installation

The Server Core installation of Windows Server is a version without a graphical user interface (GUI). It consumes fewer resources, is more secure, and requires fewer patches. You can perform the Core installation with the following steps:

1. Follow the installation steps as above.
2. On the installation type selection screen, do not select "Windows Server (Desktop Experience)". Just select "Windows Server".
3. Complete the installation.

You need to use PowerShell or the command line to manage the Core installation.

# Configure network settings
New-NetIPAddress -InterfaceAlias "Ethernet" -IPAddress 192.168.1.10 -PrefixLength 24 -DefaultGateway 192.168.1.1
