What does a network administrator do?

Day-to-day, network administrators perform a variety of different tasks, depending on the operational status of the company’s infrastructure, and any areas of specialty. Some duties and tasks include proactive maintenance, troubleshooting, meeting with other business stakeholders and new hardware deployment. Project work often also involves liaising with external agencies to arrange the installation of new services - network administrators have an intimate knowledge of a company’s network infrastructure, and are usually the best person to deal with external technical service providers.

What skills do I need to be a network administrator?

Network administrators frequently deal with both people and technology. In a technical support capacity, their IT problem solving skills are often instrumental to finding and fixing network problems and restoring network services to the business. They also rely upon their sound knowledge of IT systems and network security concepts in order to help businesses monitor and detect hackers or other network security breaches. Often, network administrators are required to communicate and work closely with network engineers to develop solutions that provide end-users with critical business capabilities, such as file sharing, email, internet access and messaging.

  • Excellent problem solving skills
  • Ability to work under time constraints
  • Communication of technical concepts to other technicians
  • Strong IT knowledge
  • Highly conscious of security


As with most IT roles, network administrators can specialise in a range of different areas. Each specialisation relies on a sound base knowledge of network technologies and basic IT concepts. Depending on the size of an organisation, some or all of these specialisations may be performed in-house or on a contract basis as required.

Messaging and communications experts provide critical services such as email, instant messaging and file sharing to a company’s employees. They are often responsible for rolling out large-scale updates to these services, as well as providing end-user technical support when things don’t work as they should.
