Windows Server 2012 Hosts File Location: A Comprehensive Guide for Dev

Hello Dev, welcome to our guide on Windows Server 2012 hosts file location. In this article, we will discuss everything you need to know about the hosts file location, how it works, and how to edit it. Whether you are a system administrator, web developer, or just a curious user, this guide will provide you with valuable insights. Let’s get started!

What is the Hosts File?

The hosts file is a plain text file that maps hostnames to IP addresses. It is used by the operating system to resolve domain names to IP addresses. Whenever you type a domain name in your web browser, the operating system first checks the hosts file to see if there is an entry for that domain. If there is an entry, it uses the corresponding IP address to connect to the website. If there is no entry, it sends a request to the DNS server to resolve the domain name.

The hosts file is a simple yet powerful tool that can be used for various purposes, such as testing websites, blocking ads, and redirecting traffic. It is often used by web developers to test their websites before making them live.

Where is the Hosts File Located in Windows Server 2012?

The hosts file is located in the same directory in all versions of Windows, including Windows Server 2012. The file is called hosts and it is located in the %SystemRoot%\system32\drivers\etc directory. The %SystemRoot% variable refers to the Windows installation directory, which is usually C:\Windows.

To access the hosts file, you need to have administrative privileges. If you are logged in as an administrator, you can simply navigate to the directory in Windows Explorer and open the file in Notepad or any other text editor. If you are not logged in as an administrator, you need to right-click on the editor and select “Run as administrator.”
