Hey Dev, are you looking for a comprehensive guide on host file location in Windows Server 2012? You’ve come to the right place! In this article, we’ll cover everything you need to know about host file location in Windows Server 2012. So, let’s get started!
What is a Host File?
A host file is a plain-text file that maps hostnames to IP addresses. It is used by the operating system to resolve hostnames to IP addresses when it is unable to do so using DNS. The host file is located on the local computer and can be edited to add or remove hostname mappings.
Can I Have Multiple Host Files?
No, you can only have one host file per computer. However, you can create multiple hostname mappings within the same file.
What is the Purpose of a Host File?
The purpose of a host file is to provide an alternative method for resolving hostnames to IP addresses when DNS is not available. This is particularly useful in situations where the local DNS server is down or unreachable. Additionally, it can be used to override DNS mappings for testing or troubleshooting purposes.
Where is the Host File Located in Windows Server 2012?
The host file is located at:
Operating System |
Location of Host File |
Windows Server 2012 |
C:\Windows\System32\drivers\etc\hosts |
It is important to note that the host file is a system file, and editing it may require administrative privileges.
How to Edit the Host File in Windows Server 2012
Step 1: Open Notepad as an Administrator
The first step to editing the host file in Windows Server 2012 is to open Notepad as an administrator. This can be done by right-clicking on the Notepad icon and selecting “Run as administrator”.
Step 2: Open the Host File
Once Notepad is open, you can open the host file by navigating to the following location:
C:\Windows\System32\drivers\etc\hosts
Alternatively, you can open the host file directly from Notepad by selecting “File” > “Open” and navigating to the host file location.
Step 3: Edit the Host File
Once you have the host file open in Notepad, you can add or remove hostname mappings as needed. Each mapping should be on a new line and follow the format:
IP Address Hostname
For example:
127.0.0.1 localhost
Save the changes to the host file once you are finished editing.
Common Issues with the Host File in Windows Server 2012
Incorrect Formatting
One common issue with the host file in Windows Server 2012 is incorrect formatting. Each hostname mapping must be on a new line and follow the format:
IP Address Hostname
If the formatting is incorrect, the host file will not work properly.
Incorrect IP Address
Another common issue with the host file is an incorrect IP address. If the IP address is incorrect, the hostname will not resolve properly.
Permissions
If you are unable to edit the host file, it may be due to permissions. Editing the host file requires administrative privileges.
