Windows Server basics for shop / small-business IT

Short orientation for techs who mostly do boards but occasionally touch a customer’s Windows Server. Roles you will meet - File Server / Share permissions, Print Server, AD DS (domain controller), RDS, Hyper-V host. Safe habits - Snapshot or backup before updates or role changes. - Prefer PowerShell remoting or RDP from a known-good admin jump box — not random public RDP. - Keep a written note of hostname, roles, and backup product. Common “it broke after patch” flow 1) Confirm the host actually boots and disks are healthy. 2) Check Event Viewer System/Application around the failure time. 3) Validate network, DNS, and time sync (Kerberos hates clock skew). 4) Roll back the last cumulative update only if you have a recovery plan. NLCRC forum is fine for “what should I check next” questions — include Server version (2016/2019/2022/2025), roles, and the exact error text.
