2. How does Windows Server licensing really work with CALs?
- Windows Server Standard and Datacenter editions require both a server license (covering the hardware cores) and Client Access Licenses (CALs) for users or devices accessing the server's services. The server license is typically purchased based on the number of physical CPU cores in the server (minimums apply).
- CALs are separate licenses. A User CAL allows a specific user to access the server from any number of devices (good for users with multiple devices like a laptop, desktop, tablet). A Device CAL allows any number of users to access the server from one specific device (good for shared workstations or devices). You need a CAL for every user or device directly or indirectly accessing server resources (like file shares, printers managed by the server, authentication via AD). CALs must be the same version as or newer than the server OS they are accessing. Hosting providers like TildaVPS typically cover the server OS license, but customers are responsible for ensuring they have the necessary CALs for their users/devices.
3. Can I run Docker containers on Windows Server?
- Yes, Windows Server has native support for running Windows Containers using Docker Enterprise Edition (often referred to as Mirantis Container Runtime now). This allows you to containerize Windows-based applications (.NET Framework, IIS, etc.). You can manage these containers using standard Docker commands and tools.
- Windows Server offers two container types: Windows Server Containers (share the host kernel for efficiency, similar to Linux containers) and Hyper-V Containers (provide higher isolation by running each container in a lightweight VM). Support and features have improved significantly in recent Windows Server versions (2019, 2022).
4. What is Server Core, and should I use it?
- Server Core is a minimal installation option for Windows Server. It includes most server roles but lacks the standard graphical user interface (GUI shell), File Explorer, and some graphical tools. It is managed primarily via command line (CMD or PowerShell) or remotely using tools like Windows Admin Center or RSAT.
- Advantages: Reduced attack surface (less code, fewer running services), lower resource consumption (less RAM/disk space), potentially fewer patches and reboots. Disadvantages: Steeper learning curve if you rely on the GUI, some applications or management tasks might be difficult or impossible without the full GUI. It's recommended for specific roles (like infrastructure servers - DCs, DNS, Hyper-V hosts) managed by administrators comfortable with command-line and remote tools.
5. How do I secure my Windows Server effectively?
- Securing Windows Server is an ongoing process involving multiple layers:
- Strong Passwords & Account Policies: Enforce complexity, history, and regular changes for all accounts, especially Administrator. Limit administrative privileges.
- Windows Updates: Keep the OS and all applications fully patched using Windows Update or a patch management system.
- Firewall Configuration: Configure Windows Defender Firewall (or a third-party firewall) to allow only necessary inbound and outbound traffic/ports.
- Anti-Malware: Install and keep updated reputable anti-malware software designed for servers.
- Least Privilege: Configure services and application pools to run under accounts with the minimum necessary permissions.
- Regular Auditing & Monitoring: Enable and review security event logs to detect suspicious activity. Use monitoring tools.
- Role-Specific Hardening: Apply security best practices specific to the roles installed (e.g., IIS hardening guides, Active Directory security best practices).

6. What is Windows Admin Center (WAC)?
- Windows Admin Center is a modern, browser-based management toolset for Windows Server (and Windows 10/11). It provides a centralized console for managing servers, clusters, hyper-converged infrastructure, and Windows PCs. It complements existing tools like Server Manager and MMC snap-ins but offers a more streamlined, web-based experience.
- WAC can manage Server Core installations effectively, providing a graphical interface for many tasks previously requiring command-line or remote MMC connections. It includes tools for viewing performance, managing certificates, devices, event logs, firewall rules, installed apps, roles & features, storage, virtual machines, and much more. It's a free download from Microsoft and can be installed on a Windows 10/11 machine or a server itself.
7. Can I downgrade a Windows Server edition (e.g., Datacenter to Standard)?
- Directly downgrading an installed Windows Server edition (like changing Datacenter to Standard on the same installation) is generally not supported by Microsoft through any simple in-place process. The typical method involves a clean installation of the desired lower edition (Standard) and migrating the roles and data from the previous installation.
- Licensing downgrade rights might exist under specific Volume Licensing agreements with Software Assurance, allowing you to use an older version or lower edition than you are licensed for, but this doesn't change the installed OS itself. Always consult Microsoft licensing documentation or a licensing specialist for specifics related to your agreements.
8. What are Shielded VMs in Windows Server Datacenter?
- Shielded VMs are a security feature introduced in Windows Server 2016 Datacenter edition (and enhanced in later versions) designed to protect virtual machine contents from compromised or malicious administrators on the virtualization host fabric.
- They leverage technologies like BitLocker encryption for the VM's virtual disk (VHDX), a virtual TPM (vTPM) for the VM, and a separate service called the Host Guardian Service (HGS). The HGS attests to the health and configuration of the Hyper-V host before allowing a Shielded VM to power on and decrypt its disk, ensuring the VM only runs on trusted, healthy hosts. This helps prevent unauthorized access, modification, or theft of data within the VM, even by host administrators.
9. What is the difference between Active Directory (AD DS) and Azure Active Directory (Azure AD)?
- Active Directory Domain Services (AD DS) is the traditional, on-premises directory service included with Windows Server. It manages users, computers, groups, and policies within a private corporate network (domain). Authentication typically uses Kerberos or NTLM.
- Azure Active Directory (Azure AD) is Microsoft's cloud-based identity and access management service. It's designed for managing user access to cloud applications (like Microsoft 365, Salesforce, etc.) and provides modern authentication protocols (OAuth 2.0, OpenID Connect, SAML). While it can sync identities from on-premises AD DS (using Azure AD Connect), it's a separate directory with different features and a flat structure (no OUs or Group Policy like traditional AD). Many organizations use both in a hybrid identity setup.
10. Is PowerShell essential for managing Windows Server?
- While you can manage Windows Server using the GUI (Server Manager, MMC snap-ins, Windows Admin Center), PowerShell has become increasingly essential for efficient and automated administration. It's a powerful command-line shell and scripting language built on the .NET Framework.
- PowerShell allows you to automate repetitive tasks, manage servers remotely at scale, configure settings not available in the GUI, and perform complex administrative workflows. Many modern Windows Server features and Azure integrations are primarily managed via PowerShell. While not strictly mandatory for basic tasks, proficiency in PowerShell significantly enhances an administrator's ability to manage Windows Server effectively and efficiently.
