Roles of Sys. Admin. & NT Admin.

There's a very good article here:
http://www.techsoup.org/articlepage.cfm?articleid=60&topicid=8

The basic responsibilities of a System Administrator are:
Staff training and support
Software installation, maintenance, and upgrading
Hardware installation, maintenance, and upgrading
Research and troubleshooting
Routine network administration and maintenance
Network documentation
Database supervision

If your system administrator also manages your network, they should have thefollowing skills:
Knowledge and experience with the type of network you have
Knowledge and experience with your office applications
Knowledge and experience with network software installation
Knowledge and experience with hardware installation and upgrades
Ability to teach and train about network use and software skills
Knowledge and experience with network email is helpful
Dedication to appropriate uses of computer technology (the ability to use and adapt older equipment)
Some ofthe day-to-day support tasks a system administrator should perform include:
Doing backups of your staff's computers, and of the server, if you have one
Adding and deleting new network users
Making sure that virus protection software is up to date, and clean any viruses that infect staff computers
Training and assisting staff in using their hardware and software efficiently
Troubleshooting any routine problems that staff cannot fix on their own, such as a problem with the printer or a computer that freezes repeatedly

The terms are frequently interchanged. Take a look at SAGE...this link in particular:
