The Network Administrator will concentrate on the overall health of the network, server deployment, security, ensuring network connectivity throughout and company's LAN/WAN infrastructure, and all other technical considerations at the network level of an organizations technical hierarchy. Network Administrators are considered Tier 3 support personnel that only work on break/fix issues that could not be resolved at the Tier1 (helpdesk) or Tier 2 (desktop/network technician) levels.

In some companies, the Network Administrator may also design and deploy networks. Usually, though, these tasks would be assigned to aNetwork Engineer if the company is large enough.

The actual role of the Network Administrator will vary from company to company, but usually includes tasks such as network address assignment, assignment of routing protocols and routing table configuration as well as configuration of authentication and authorization – directory services. It often includes maintenance of network facilities in individual machines, such as drivers and settings of personal computers as well as printers and such. It sometimes also includes maintenance of certain network servers: file servers, VPN gateways, intrusion detection systems, etc.
