Day-to-Day Responsibilities
Set up and maintain physical and virtual servers running Windows Server or Linux.
Create, change and remove user accounts, passwords and access rights, usually through Active Directory or a similar directory service.
Monitor systems for performance problems, outages, and disk or memory issues, then fix them or escalate them.
Install security patches and software updates on a schedule, testing them first so business applications are not disrupted.
Plan and check backups, and carry out restores when files or systems are lost.
Configure and troubleshoot networks, including DNS, DHCP, firewalls and VPN access, in coordination with network teams.
Write scripts to automate routine tasks, and keep clear documentation and change records for every change.
