Installing and Configuring a Server

Before installing Windows Server, an administrator needs to decide the installation type (Server Core or Desktop Experience), the edition (Standard or Datacenter), whether the target is physical hardware or a virtual machine, and how storage will be partitioned. Installation media is typically an ISO mounted to a VM or written to a bootable USB drive for physical hardware, and the setup wizard walks through language selection, edition selection, accepting the license terms, and choosing between a custom (clean) install and an upgrade of an existing OS. For production environments, a custom install onto a dedicated volume is almost always preferred over an in-place upgrade, since it avoids carrying forward legacy configuration drift.

The Windows Server setup wizard partitions and formats the target disk, copies installation files, expands them, and installs features, followed by a reboot to finalize the install. On first boot, you're prompted to set the local Administrator password — there is no default password, and Windows enforces its complexity policy immediately. If installing on Server Core, you land directly at a command prompt after this; on Desktop Experience, you land at the familiar Windows desktop with Server Manager launching automatically to prompt for the next configuration steps.

Once installed, a handful of tasks are essential before the server is production-ready: renaming the computer from its default WIN-XXXXXXX name, assigning a static IP address and DNS servers instead of relying on DHCP, joining the machine to the correct Active Directory domain (or leaving it in a workgroup for standalone roles), and enabling remote management so it can be administered without a local console session. On Server Core, all of this can be done through the Sconfig menu without touching PowerShell directly, though PowerShell offers the same capability for scripted, repeatable deployments across many servers.

After the basics are set, harden the server before exposing it to production traffic: enable and configure Windows Firewall with only the rules needed for the server's role, turn on automatic or WSUS-managed Windows Update so security patches apply on schedule, disable unnecessary services and roles that aren't actually needed, and set the time zone plus verify NTP time synchronization, which matters enormously for Kerberos authentication once the server joins a domain. Skipping time synchronization is a classic mistake — Kerberos tickets fail validation when clocks drift more than five minutes from the domain controller, breaking authentication in ways that are confusing to diagnose.
