Windows Server 2016 Installation Guide

This guide walks through the installation and configuration of Windows Server 2016 in VirtualBox, including initial domain setup.

Prerequisites

System Requirements

• VirtualBox 5.2 or later
• 64-bit processor with virtualization support
• Minimum 2 GB RAM (512 MB absolute minimum)
• At least 32 GB disk space
• Windows Server 2016 ISO image

Refer to the official Windows Server 2016 system requirements for complete details.

Creating the Virtual Machine

1. Create New VM

   1. Open VirtualBox and click New
   2. Set Name: Windows2016Server
   3. VirtualBox auto-selects:
      • Type: Microsoft Windows
      • Version: Windows 2016 (64-bit)
2. Allocate Memory

   Assign 2048 MB (2 GB) RAM as recommended.

3. Create Virtual Hard Disk

   1. Select Create a virtual hard disk now
   2. Type: VDI (VirtualBox Disk Image)
   3. Storage: Dynamically allocated
   4. Size: At least 40 GB
4. Configure Network

   Set to NAT for basic connectivity (can be changed later for domain configurations).

5. Attach ISO

   1. Settings → Storage
   2. Select optical drive
   3. Attach Windows Server 2016 ISO

Installing Windows Server 2016

1. Boot Installation Media

   Start the VM. VirtualBox will boot from the ISO automatically on a new VM.

2. Select Language

   Choose installation language, time format, and keyboard.

3. Install Now

   Click Install now.

   The Repair your computer option is for troubleshooting existing Windows installations.

4. Select Edition

   Choose the Windows Server 2016 edition (Standard or Datacenter, with or without Desktop Experience).

   Desktop Experience provides a full GUI. Without it, you get Server Core (command-line only).

5. Product Key

   • Enter your product key if available
   • Or select I don’t have a product key to activate later
6. Accept License

   Read and accept the license terms.

7. Installation Type

   Select Custom: Install Windows only (advanced).

8. Partition Disk

   Select the unallocated space and click Next. Windows will create necessary partitions automatically.

9. Installation Progress

   Wait for files to copy and install. The system will restart automatically.

Initial Server Configuration

1. Set Administrator Password

   Unlike desktop Windows, the administrator account is pre-defined as:

   • Username: Administrador (or Administrator in English)
   • Password: Set your own (e.g., #admin1s0#)

   Server requires complex passwords: uppercase, lowercase, numbers, and special characters.

2. Login

   Press Ctrl+Alt+Del (or use VirtualBox’s Input menu) and enter the administrator password.

3. Server Manager

   Server Manager launches automatically, showing the configuration wizard.

Windows Server Essentials Configuration

If you installed Windows Server 2016 Essentials, a configuration wizard will guide you through domain setup.

1. Welcome Screen

   Click through the initial welcome wizard.

2. Set Time and Date

   Configure timezone and system time.

   Accurate time is critical for Kerberos authentication in domain environments!

3. Configure Company Information

   • Company Name: Your organization name
   • Internal Domain Name: e.g., empresa.local
   • NetBIOS Name: Usually auto-filled
4. Create Network Administrator

   Set up the domain administrator account:

   • Username: netadminiso
   • Password: #netadmin1s0#

   This account has full control over the domain, separate from the local Administrator account.

5. Update Settings

   Select Use recommended settings for automatic updates.

6. Complete Configuration

   Wait for the server to complete configuration. This process can take several minutes.

7. Restart

   Restart the server when prompted. You must provide a reason:

   • Select Other (Unplanned)
   • Add a comment if desired

Configure DNS Forwarding

After creating a domain, the server becomes its own DNS server. To resolve external names, you need to configure DNS forwarders.

1. Open DNS Manager

   1. In Server Manager, click Tools
   2. Select DNS
2. Add Forwarder

   1. Right-click your server name
   2. Select Properties
   3. Go to Forwarders tab
   4. Click Edit
   5. Add a public DNS server: 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google)
3. Test Internet Access

   Open Internet Explorer and verify you can browse external websites.

Next Steps

Your Windows Server 2016 is now configured with:

• Active Directory Domain Services
• DNS Server
• Basic domain infrastructure

You can now:

• Join client computers to the domain
• Create user accounts
• Configure Group Policy
• Set up file shares
• Install additional server roles

Default Credentials Summary

• Local Admin: Administrador / #admin1s0#
• Domain Admin: netadminiso / #netadmin1s0#

Troubleshooting

Can't browse the internet

Ensure DNS forwarders are configured in DNS Manager. Without them, the server can only resolve names within its own domain.

Can't join computers to domain

• Verify network mode is Bridged Adapter or Internal Network
• Check that both server and client can ping each other
• Ensure client DNS points to the domain controller
• Verify firewall settings
