Lab Requirements and Prerequisites
Hardware Requirements
Your host computer needs sufficient resources to run multiple virtual machines simultaneously. Here are the minimum and recommended specifications:
Minimum configuration:
- CPU: Dual-core processor with virtualization support (Intel VT-x or AMD-V)
- RAM: 8GB (allows 1 server VM + 1 client VM)
- Storage: 80GB free disk space
- OS: Windows 10/11, macOS, or Linux
Recommended configuration:
- CPU: Quad-core processor or better
- RAM: 16GB+ (enables multiple servers and clients)
- Storage: 120GB+ SSD for faster performance
- OS: Windows 11 Pro or Enterprise
⚠️ Critical Requirement: You must enable virtualization in your BIOS/UEFI settings. Without this, virtual machines won’t run or will be extremely slow. Check your motherboard manual for “Intel VT-x” or “AMD-V” settings.
Software Downloads
Gather these components before starting your lab setup:
Virtualization platform (choose one):
- VMware Workstation Player (free for non-commercial use): Download

Troubleshooting Common Issues
VM Won’t Boot or Runs Very Slowly
Problem: Virtual machine doesn’t start or performance is terrible.
Solution:
- Verify virtualization is enabled in BIOS/UEFI
- Restart computer and enter BIOS (usually F2, F10, Del, or Esc key during boot)
- Look for “Intel VT-x” or “AMD-V” or “Virtualization Technology”
- Enable the setting, save, and exit BIOS
No Internet Connectivity in VM
Problem: Cannot ping external addresses or download updates.
Solution:
- Check VMware network adapter is set to NAT or Bridged
- Verify your host computer has internet access
- In Windows Server, run
ipconfig /allto verify gateway and DNS settings - Try pinging your default gateway:
ping 192.168.1.1
Can’t Promote to Domain Controller
Problem: “Password does not meet complexity requirements” error during DC promotion.
Solution:
- Your administrator password must meet complexity requirements
- Change password before AD installation:
- Tools > Computer Management > Local Users and Groups > Users
- Right-click Administrator > Set Password
- Use complex password:
P@ssw0rd123
Client Can’t Join Domain
Problem: Windows 11 machine shows “Domain could not be contacted” when joining.
Solution:
- Verify client’s DNS points to domain controller IP (
192.168.1.10) - Ping domain controller from client:
ping 192.168.1.10 - Ping domain name from client:
ping lab.local - Ensure both VMs use same network type (both NAT or both Bridged)
- Check Windows Firewall isn’t blocking connections
Login Issues After Domain Promotion
Problem: Can’t log in using Ctrl+Alt+Del keyboard shortcut.
Solution:
- In VMware, use Ctrl+Alt+Insert instead of Ctrl+Alt+Del
- This sends the key combination to the VM instead of your host OS
