What Does a Network Administrator Do? Main Tasks and Responsibilities

Updated December 2023

Organizations in every industry rely on computer networks. Businesses, hospitals, schools, and government agencies (just to name a few) use networking technology to share information and resources every single day.

Computer networks are systems connected by cables (wired) or wi-fi (wireless). Networks are built using hardware and software and in different configurations depending on the needs of the users.

This includes both LANs (local area networks) and WANs (wide area networks). 

When an organization uses a computer network, they also require someone to maintain, protect, update, and troubleshoot it. That’s where network administrators come in. 

In this post, we’ll explore the main skills and responsibilities of a network administrator. Find out exactly what a network administrator does and the skills you'll need to get hired.

Role and Responsibilities of a Network Administrator 

Network administrators are hired by organizations or IT companies to install and maintain computer networks.

This work includes performing regular maintenance, optimization, network security, troubleshooting, upgrades, and disaster recovery operations as needed. 

There are many moving parts to a computer network, so there is much variety in the role of a network administrator. No two workdays are exactly the same.

One day you might be dealing with a company-wide security breach, and the next day you could be tasked with updating software or training new users on how to operate a system. 

The role of a network administrator offers a balance of working with others and working independently behind a computer screen.

Main tasks for network administrators include:

☑️ Troubleshooting hardware, software, connectivity, and server issues

☑️ Performing backup operations

☑️ Configuring cloud services

☑️ Installing and configuring individual workstations

☑️ Training users on how to use hardware or software

☑️ Monitoring network security

☑️ Maintaining network documentation

Network Administrator Skills

Network administrators need excellent technical knowledge combined with strong customer service and communication skills.

You need a deep understanding of networking hardware, software, optimization, and security. But at the same time, you must be able to break those concepts down and explain them to everyday users and clients.

A complete skillset for networking administrators includes:

☑️ Strong interpersonal skills

☑️ Ability to present complex ideas in user-friendly language

☑️ Patience and attention to detail

☑️ Proactive problem-solving

☑️ Clear communication, oral and written

☑️ Ability to meet deadlines and work under pressure

☑️ Strong analytical and research skills

☑️ Willing to continue learning and developing new skills


What else do employers look for in network administrators?

It's not just about understanding networking technologies. Soft skills such as communication and teamwork are highly valued by employers in this field.

Dice Insights wisely points out that automation is slowly creeping into the IT and tech sector.

Companies are looking for network administrators with skills that can't be automated, like advanced problem-solving, communication, and innovation.

"Automation can execute any number of tasks necessary to keep networks and IT infrastructure running, but companies know a human being is ultimately necessary to make nuanced decisions and take a holistic view of the system."

Future-proof your network administration career by working on those soft skills and highlighting them during interviews.
