IT Systems Administrator

1. 1
   Earn CompTIA A+ for the Foundation

   CompTIA A+ (two exams, $246 each) is the entry-level IT credential covering hardware troubleshooting, operating systems, networking basics, security fundamentals, and troubleshooting methodology. Professor Messer's free A+ course (YouTube) is the best free study resource. A+ is a prerequisite for most entry IT positions and signals foundational technical competency to employers. With A+, entry-level help desk or desktop support positions become accessible — the typical starting point for sysadmin careers.

   Add CompTIA Network+ and Security+

   Net+ covers networking fundamentals at depth: OSI model, TCP/IP, subnetting, routing protocols, VLANs, wireless, and network troubleshooting. Security+ adds: threat identification, security architecture, access control, cryptography, and incident response. These three CompTIA certifications together (the "Trifecta") validate the knowledge foundation for sysadmin work. The DoD approves Security+ for technical cybersecurity positions — it opens government sysadmin roles.

   Develop Windows Server and Active Directory Expertise

   Most enterprise environments run Windows Server and Active Directory — the core Microsoft infrastructure stack. Skills: AD user and group management, Group Policy, DNS and DHCP administration, file share permissions, Windows Server backup and recovery, and PowerShell scripting for automation. Microsoft Certified: Windows Server Hybrid Administrator Associate (AZ-800/801) validates current Windows Server skills including the hybrid on-premises + Azure integration that most enterprises are implementing.

   Add Cloud Administration — AWS or Azure

   The sysadmin role is evolving from purely on-premises to hybrid cloud. AWS SysOps Administrator — Associate ($300) validates AWS operational skills: monitoring, deployment, security, networking, and cost optimization for production AWS environments. Microsoft Azure Administrator (AZ-104, $165) validates Azure administration. Both credentials open the higher end of sysadmin compensation and position for cloud engineer career advancement.

   Develop Automation and Scripting

   The highest-value sysadmin skill beyond core administration: automation. PowerShell for Windows automation (user provisioning, report generation, policy enforcement), Bash for Linux automation, and Python for more complex scripting. A sysadmin who automates repetitive tasks is more productive and more valuable — and is positioning themselves for DevOps and platform engineering career advancement. Build a GitHub repository of your automation scripts.

• 8:00 AMMorning check — review server monitoring dashboard (PRTG): all systems green except one — a file server showing high disk utilization (92%). Check: which directories are consuming space. Find: a user's home folder with 80GB of uncompressed video files. Email the user per policy, archive to network storage, space freed.
• 9:00 AMActive Directory work — 3 new employees starting Monday. Create user accounts in AD: set up group memberships per department, configure email in Exchange Online, provision licenses in Microsoft 365 admin center, set initial password, and send welcome credentials to HR.
• 10:00 AMWindows Server update — monthly patch Tuesday. Review available patches in WSUS. Stage critical security patches for test deployment on the dev servers, schedule production deployment for Saturday 2 AM maintenance window. Create change ticket per change management policy.
• 12:00 PMLunch — 30 minutes.
• 1:00 PMVPN troubleshooting — an executive is unable to connect to the VPN from home. Remote desktop to her laptop: Cisco AnyConnect shows "certificate validation failure." Check the certificate store — the corporate root CA certificate has expired on her machine. Push the updated certificate via Group Policy. VPN connects.
• 2:30 PMAzure work — provision 3 new Azure virtual machines for the development team per the approved request. Configure in the correct VNet/subnet, apply the required tags for cost allocation, set up Azure Backup, and add to the monitoring workspace. Document in the asset management system.
• 4:00 PMPowerShell automation — write a script to generate a weekly report of disabled user accounts that still have mailboxes. Schedule in Windows Task Scheduler to email the IT manager every Monday. This used to take 45 minutes manually — now it's automatic.

Systems administrators manage enterprise IT infrastructure — a role where routine maintenance and monitoring are increasingly automated, but complex troubleshooting, security response, and vendor management remain human work. The +3% growth is modest; advancement toward cloud and security roles is the strongest career strategy.
