  • Implement changes during approved maintenance windows
  • Monitor system health during and after changes
  • Document actual configuration as implemented

Validation Phase

  • Verify all functionality works as expected
  • Test authentication and authorization scenarios
  • Validate replication is working correctly
  • Confirm integration points are functioning
  • Update documentation with final configuration
  • 📖 Fundamentals: Core concepts needed for configuration
  • 🔧 Operations: Ongoing maintenance and monitoring
  • 🛠️ Procedures: Step-by-step configuration procedures
  • 🔒 Security: Security configuration and hardening

Quick Reference

Common Configuration Commands

# Install AD DS role
Install-WindowsFeature AD-Domain-Services -IncludeManagementTools

# Promote server to domain controller
Install-ADDSForest -DomainName "contoso.com" -InstallDns

# Configure additional domain controller
Install-ADDSDomainController -DomainName "contoso.com"

# Configure site and subnet
New-ADReplicationSite -Name "Branch-Office"
New-ADReplicationSubnet -Name "192.168.1.0/24" -Site "Branch-Office"

Configuration Validation

# Test domain controller functionality
dcdiag /v /c /d /e /s:DomainController

# Check replication status
repadmin /replsummary /bysrc /bydest

# Validate DNS configuration
nslookup -type=SRV _ldap._tcp.dc._msdcs.contoso.com

# Test authentication
nltest /sc_query:contoso.com

Proper configuration is the foundation of a reliable and secure Active Directory environment. Take time to plan, test, and document all configuration changes.
