help
cost, capacity planning, logistics (network design, server locations, where to install, wiring, IP address assignments, ...), network service providers (ISPs)
Planning
temperature, humidity, electrical, fire, security, EIA/TIA wiring closet and cabling standards, UPS; Change management (preparing for any service changes)
Preparing
computers, terminals, disk drives, CD-ROMs, RAM, printers, NICs, cabling
Installing Hardware
regular preventative maintenance (daily, weekly, ...), boot and shutdown systems when needed, printers, backup media, tune systems for performance
Maintaining
printers, disk space, network, servers and workstations, performance, and security, and all log files regularly
Monitoring
OS (kernel patches, new device drivers, ...), applications (new versions, DLLs, new configurations), documentation
Installing/upgrading/removing software

Maintaining local documentation
This includes working with your management (who sometimes needs the most help and education even if they don't think so), helping new users, experienced users, and yourself
Help & Educate users
Generate system reports and correlate growth, changes over time. (Use data to order supplies, spares, hardware and software upgrades in a timely manner, and to generate reports to management)
Baselining
System administration is about solving problems, not memorizing how-to directions. Often something won't work as it should. What will you do then?
Problem Solving
books, netnews, man pages, on-line (www.tldp.org, docs.sun.com, www.redhat.com, ...)
Know where to look for help
