Network administration guide

Good network administration is the backbone of today's technology-dependent enterprises. Network administrators are charged with keeping expansive networks and numerous applications running smoothly, and the job can seem overwhelming at times. We're coming to the rescue with this guide that brings you back to basics. We polled our readers about their most common tasks to find out what the heart and soul of network administration consists of on a daily basis. Here we've outlined the main topics, such as network design, troubleshooting, backup, documentation, security, and managing users.

Network administration is an arduous task. The administrator's responsibilities often involve many different aspects and may include such tasks as network design, management, troubleshooting, backup and storage, documentation, security and virus prevention as well as managing users.

While the specific job description for network administrators will be slightly different for each organization, common responsibilities include:

This guide will help you with each step and responsibility. Refer back to it often when you have questions or need advice in each specific area.

 

Immediate to-do's: Do these before completing any other step in this guide

  1. Backups and recovery disks, RAID and images (Veritas, ArcServe, ghost, imagecast)
    1. Are operating system recovery disks requited (server or workstation)? Have they been created recently, copies and placed in a safe location?
    2. Are backup recovery disks needed?
    3. Is a full backup being made on a routine basis? Have you placed a verified, full backup in a safe, offsite location?
    4. Are daily, incremental backups being made? (They should be!)
    5. Do any other software packages require or allow recovery diskettes? Have they been created and stored in a safe location? (Antivirus, operating system, applications, etc.)?
    6. Is RAID and/or disk mirroring enabled and verified that it is functioning correctly?
  2. Service packs, critical updates, security updates: Are the latest of these installed? Is there a schedule for updating these items? (Weekly or monthly)
  3. Antivirus installed and updated? Recovery disks required? Is automated scan enabled and running? Are automatic download updates or push downs of updated DAT files available and configured? Is there a schedule for updating these items? (Weekly or monthly)
  4. Complete steps 1, 2 and 3 and then perform a full backup and store in a safe location.
  5. Secure physical access to the servers, enable BIOS passwords, lock server room, ensure battery backups are installed and operating properly. Is the power supply adequare for the number of devices you have plugged in?
  6. Verify and record all software licenses in possession. Are additional licenses required? Remember you could be liable for this!

Use your PDA and/or calendar feature in your mail program to schedule and remind you of these critical items.
