Before you begin the installation process, it is essential to plan your network settings and gather all the necessary information. This will ensure that your server can communicate effectively with other devices on the network and access the internet if needed. One of the first things you need to decide is whether you will use a static IP address or a dynamic IP address. A static IP address is a fixed address that you manually assign to the server. This is often preferred for servers because it ensures that the server always has the same address, making it easier to access and manage. A dynamic IP address, on the other hand, is assigned automatically by a DHCP server. This is more commonly used for client devices, such as desktops and laptops. If you choose to use a static IP address, you will need to obtain an available IP address from your network administrator or determine one based on your network's addressing scheme. You will also need to know your subnet mask, default gateway, and DNS server addresses. The subnet mask defines the range of IP addresses that are within your local network. The default gateway is the IP address of the router that connects your network to the internet. The DNS server addresses are the IP addresses of the servers that translate domain names into IP addresses. If you are using a dynamic IP address, you will need to ensure that your network has a DHCP server configured and that it is properly assigning IP addresses. The DHCP server will automatically assign an IP address, subnet mask, default gateway, and DNS server addresses to your server when it boots up. In addition to IP addressing, you will also need to configure other network settings, such as the server's hostname and domain membership. The hostname is a unique name that identifies your server on the network. The domain membership determines whether your server is part of a domain or a workgroup. A domain is a centralized network environment that allows for centralized user and device management. A workgroup is a decentralized network environment where each device is managed independently. If you are planning to join your server to a domain, you will need to know the domain name and have the necessary permissions to join the domain. You will also need to ensure that your server can communicate with the domain controller. Before you start the installation process, it is a good idea to document your network settings. This will make it easier to configure your server during the installation and troubleshoot any network issues that may arise. You should also keep a copy of your network settings in a safe place in case you need to refer to them in the future.

A strong and secure administrator password is one of the most important security measures you can take to protect your Windows Server 2012 R2 server. The administrator account has full access to the system and can make any changes, so it is crucial to choose a password that is difficult to guess or crack. Your administrator password should be at least 12 characters long and include a combination of uppercase and lowercase letters, numbers, and symbols. Avoid using common words, names, or dates, as these are easily guessed. You should also avoid using the same password for multiple accounts. A strong password is your first line of defense against unauthorized access to your server. If an attacker gains access to the administrator account, they can do serious damage, such as installing malware, stealing data, or disrupting services. Therefore, it is essential to choose a password that is strong and secure. In addition to choosing a strong password, you should also take other steps to protect the administrator account. For example, you can disable the built-in administrator account and create a new account with administrator privileges. This makes it more difficult for attackers to guess the account name. You should also enable account lockout policies, which will prevent attackers from trying to guess the password repeatedly. Account lockout policies will lock the account after a certain number of failed login attempts. This prevents attackers from using brute-force attacks to guess the password. It is also a good idea to enable multi-factor authentication for the administrator account. Multi-factor authentication requires users to provide multiple forms of identification, such as a password and a code from a mobile app. This makes it much more difficult for attackers to gain access to the account, even if they know the password. You should also regularly review and update your administrator password. It is recommended to change your password every 90 days. This helps to prevent attackers from gaining access to the account if they have managed to crack the password. When you create your administrator password, make sure you write it down and store it in a safe place. You should also have a recovery plan in case you forget your password. This may involve creating a password reset disk or using a password recovery tool. By choosing a strong and secure administrator password and taking other steps to protect the account, you can significantly reduce the risk of unauthorized access to your Windows Server 2012 R2 server. This will help to ensure the security and integrity of your server and the data it contains.
With these prerequisites in mind, you're well-prepared for a smooth and successful installation.
