System network administrators oversee and support the day-to-day operation of computer systems and networks throughout an organization, ensuring reliable performance and data integrity in local area networks (LANs), wide area networks (WANs), and organization intranets. In this role, system network administrators evaluate a business’ needs while setting up and maintaining computer networks, monitoring network and system performance, and collecting data to enhance security and reliability.
System network administrators provide direct support to end users, particularly during system setup and installation, as well as during network changes. This can include helping users install software and ensuring that it works with their network settings and operating system, troubleshooting connection or performance issues, or providing guidance on IT-related processes and procedures. In some organizations, the system network administrator may also resolve help desk queries.
The system network administrator designs and administrates many of the backend or server-side elements of an organization’s network architecture. This can include installing network-wide antivirus programs or firewalls, configuring databases and access, and deploying server-side upgrades to enhance performance. The system network administrator also periodically evaluates the need to upgrade or repair these systems while limiting the impact of these changes on employees.
