A network administrator maintains computer infrastructures with emphasis on networking. Responsibilities may vary between organizations, but on-site servers, software-network interactions as well as network integrity/resilience are the key areas of focus.
The role of the network administrator can vary significantly depending on an organization’s size, location, and socio-economic considerations. Some organizations work on a user-to-technical support ratio, whilst others implement many other strategies.
Generally, in terms of reactive situations (i.e.: unexpected disruptions to service, or service improvements), IT Support Incidents are raised through an Issue tracking system. Typically, issues work their way through a Help desk and then flow through to the relevant technology area for resolution. In the case of a network related issue, an issue will be directed towards a network administrator. If a network administrator is unable to resolve an issue, a ticket will be escalated to a more senior network engineer for a restoration of service or a more appropriate skill group.
Network administrators are often involved in proactive work.
