Active Directory Troubleshooting for IT Support

Explore why using virtual machines enhances Windows server and client troubleshooting, set up labs with VirtualBox or VMware, and balance host and guest RAM for safe, hands-on practice.

Set up a practical lab with one domain and one client using VMware Workstation, Windows Server, and a domain controller to practice Active Directory troubleshooting.

Verify hardware readiness for the lab by checking memory, storage, processor count, 64-bit host status, and virtualization settings in Task Manager, Device Manager, and BIOS.

Master active directory troubleshooting for IT support across Windows 10 and Windows 11, with labs on Windows 10 client and Windows Server 2016, applicable to Windows 11 and Windows Server 2019.

Download and install VMware Workstation 15 or above in stage one, then click next finish, and note you cannot run VMware and VirtualBox simultaneously on the same host.

Set up the lab network with the virtual network editor by creating a private class C network 192.168.100.x named VM net10, enable DHCP, and share it from host to VMs.

Download the Windows Server ISO from Microsoft, create a new virtual machine, install Windows Server 2016, attach the ISO, and upgrade to a domain controller using a custom NAT network.

Set up a Windows server in a virtual machine, install and configure a domain controller with DNS, assign a static IP, install VM tools, and verify network connectivity.

Set up a Windows Server domain controller by configuring VM, installing server, renaming and networking, then promoting the server to a new forest with Active Directory domain services.

Stage four guides installing Windows 10 in a lab using a downloaded iso and creating a virtual machine in Beam workstation; it notes company setup differences and upcoming domain join.

Learn how to join a Windows 10 VM to a domain, troubleshoot domain join issues, rename workstations, and update Active Directory records and network settings.

Clarify the difference between hostname and domain name in the lab, noting that videos may show different domain names (Tarek Local vs Leyla Lacalle) due to lab rebuilds.

Explore how Active Directory stores passwords and user information for computers, printers, and shared folders, enabling domain join for centralized authentication across devices.

Discover two methods to access Active Directory: remote into the server or install Active Directory on Windows 10 using a domain account to reset passwords and troubleshoot permissions.

Install Active Directory on Windows 10 using remote tools linked to a server, understanding client versus server editions and accessing the Active Directory Users and Computers snap-in via control panel.

Create organizational units under the domain to group users by location, such as Singapore, USA, and Japan, apply location-specific group policies, and protect units from accidental deletion.

Create a new user in Active Directory by selecting domain, entering the login and full name, setting a password per policy, enforcing password change at first login, and finalizing access.

Learn to reset user passwords using workflows and company ID verification, never by phone. Perform Active Directory password resets with a temporary password and require change at next login.

Unlock a locked Active Directory user account by locating the user on the domain controller, opening account properties, and clicking unlock; then reset the password if needed.

Learn how Windows 10 joins a domain by configuring network properties, setting IP and DNS, and authenticating with a domain administrator. Clarify domain membership versus workstation status.

Learn to troubleshoot cannot join the domain by checking network connectivity, LAN cable, and server reachability; verify and refresh Active Directory hostname, wait 20–30 minutes, retry or reimage if needed.

Diagnose and fix the common security database 'no computer account' issue by rejoining the domain, using local and domain accounts, and ensuring a wired local area network connection on-site.

Learn how BitLocker encrypts the hard drive, suspend protection before RAM upgrades, resume after changes, and retrieve the 48-digit recovery key via Active Directory if needed.

Learn the difference between serial numbers and hostnames, why serial numbers are unique and warranty-relevant, and three ways to locate each, including stickers, system information, and command prompts.
