Prerequisites

Before starting the configuration, ensure you have the following:

• A valid Windows Server 2025 license
• A machine meeting the minimum hardware requirements
• Internet connectivity for updates and downloads
• Administrative access to the server

Installation Process

1. Obtain the Installation Media

Download the Windows Server 2025 ISO from the official Microsoft website. Ensure you have the correct version for your hardware architecture (x64).

2. Create a Bootable USB Drive

Use a tool like Rufus to create a bootable USB drive from the downloaded ISO file. Insert the USB drive into your server machine.

3. Boot from the USB Drive

Restart your server and boot from the USB drive. This usually involves pressing a key (such as F2, F12, or Del) during startup to enter the boot menu.

4. Start the Installation

Follow the on-screen instructions to begin the installation. Select the appropriate language, time, and keyboard settings, and then click “Install Now.“

5. Enter Product Key

Enter your Windows Server 2025 product key when prompted. Choose the correct edition that matches your license.

6. Select Installation Type

Opt for a custom installation to install Windows Server 2025 on a clean drive. Choose the drive where you want to install the OS and click “Next.”

7. Complete Installation

The installation process will take some time. Once completed, the server will restart, and you will be prompted to create an administrator password.

Initial Configurations

1. Set Up Initial Administrator Account

Log in using the administrator account you created during installation. Ensure you use a strong password to enhance security.

2. Configure Time Zone

Set the correct time zone for your server to ensure accurate timekeeping, which is crucial for logging and scheduling tasks. Go to Settings > Time & Language > Date & Time.

3. Update Windows Server

Run Windows Update to ensure your server has the latest patches and security updates. This can be done via Settings > Update & Security > Windows Update.

Network Setup

1. Configure Network Interfaces

Access the Network and Sharing Center from the Control Panel. Set up the IP address, subnet mask, default gateway, and DNS servers as per your network configuration.

2. Enable Remote Desktop

Remote Desktop allows you to manage the server remotely. Enable it by going to Settings > System > Remote Desktop and turning on the remote desktop feature.

3. Configure Firewall

Ensure the Windows Firewall is properly configured to allow necessary traffic. You can manage firewall settings via Control Panel > System and Security > Windows Defender Firewall.

Role and Feature Installation

1. Open Server Manager

Server Manager is your central hub for managing server roles and features. Access it from the Start menu.

2. Add Roles and Features

Select “Add roles and features” from the Server Manager dashboard. Follow the wizard to select and install the roles and features you need. Common roles include:

• Active Directory Domain Services (AD DS)
• DNS Server
• DHCP Server
• File and Storage Services
• Web Server (IIS)

3. Configure Installed Roles

Each role will require specific configurations. For example, if you installed AD DS, you will need to promote the server to a domain controller. Follow the post-installation configuration wizard for each role.

Security Best Practices

1. Enable Windows Defender

Ensure Windows Defender is active and updated. This provides real-time protection against malware and other threats.

2. Configure Security Policies

Use the Group Policy Management Console to enforce security policies across your server environment. Common policies include password complexity requirements and account lockout policies.

3. Implement Network Security Measures

Configure your network firewall and intrusion detection/prevention systems (IDS/IPS) to protect against external threats. Ensure only necessary ports are open.

4. Regular Backups

Implement a robust backup strategy to protect your data. Use Windows Server Backup or a third-party solution to perform regular backups.

5. Monitor and Audit

Regularly monitor server logs and audit access to detect any suspicious activity. Use tools like Event Viewer and third-party monitoring solutions.

Troubleshooting Common Issues

1. Installation Failures

Ensure your hardware meets the minimum requirements and that you are using the correct installation media. Check for any error codes and refer to Microsoft’s support documentation.

2. Network Connectivity Problems

Verify IP configurations, check cable connections, and ensure the network interface is enabled. Use tools like ping and tracert to diagnose network issues.

3. Role Installation Errors

Review the installation logs for any errors. Ensure all prerequisites for the role are met and that no conflicting software is installed.

4. Performance Issues

Monitor server performance using Task Manager and Performance Monitor. Identify resource bottlenecks such as CPU, memory, or disk usage and address them accordingly.

Conclusion

Configuring Windows Server 2025 involves a series of meticulous steps to ensure your server is secure, efficient, and ready to handle your organizational needs. By following this guide, you can set up a robust server environment that leverages the latest features and best practices. Remember to keep your server updated, implement strong security measures, and regularly monitor its performance to maintain optimal operation.
