.NET AD Enum commands

There are times you don’t have access to the Active Directory PowerShell cmdlets. One of the great things about PowerShell is the ability to use .Net in PowerShell scripts. For more, check out Part 2.

Here are some alternatives to using Get-ADForest & Get-Domain:

 

# Get Active Directory Forest Information
$ADForestInfo = [System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest()
$ADForestInfo.Name
$ADForestInfo.Sites
$ADForestInfo.Domains
$ADForestInfo.GlobalCatalogs
$ADForestInfo.ApplicationPartitions
$ADForestInfo.ForestMode
$ADForestInfo.RootDomain
$ADForestInfo.Schema
$ADForestInfo.SchemaRoleOwner
$ADForestInfo.NamingRoleOwner
# OR
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().Name
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().Sites
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().Domains
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().GlobalCatalogs
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().ApplicationPartitions
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().ForestMode
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().RootDomain
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().Schema
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().SchemaRoleOwner
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest().NamingRoleOwner
###
# Get Active Directory Domain Information
  # Target the current (local) computer’s domain:
  $ADDomainInfo = [System.DirectoryServices.ActiveDirectory.Domain]::GetComputerDomain()
  # Target the current user’s domain:
  $ADDomainName = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()
$ADDomainInfo.Forest
$ADDomainInfo.DomainControllers
$ADDomainInfo.Children
$ADDomainInfo.DomainMode
$ADDomainInfo.Parent
$ADDomainInfo.PdcRoleOwner
$ADDomainInfo.RidRoleOwner
$ADDomainInfo.DomainControllers
# OR
[System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain().Forest
[System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain().DomainControllers
[System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain().Children
[System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain().DomainMode
[System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain().Parent
[System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain().PdcRoleOwner
[System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain().RidRoleOwner
[System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain().DomainControllers
# Note: Use [System.DirectoryServices.ActiveDirectory.Domain]::GetCOMPUTERDomain().Attribute for the local computer’s domain info.
# Example: [System.DirectoryServices.ActiveDirectory.Domain]::GetCOMPUTERDomain().Forest
###
# Get the local computer’s site information:
$LocalSiteInfo = [System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite()
$LocalSiteInfo.Name
$LocalSiteInfo.Domains
$LocalSiteInfo.Subnets
$LocalSiteInfo.Servers
$LocalSiteInfo.AdjacentSites
$LocalSiteInfo.SiteLinks
$LocalSiteInfo.InterSiteTopologyGenerator
$LocalSiteInfo.Options
$LocalSiteInfo.Location
$LocalSiteInfo.BridgeheadServers
$LocalSiteInfo.PreferredSmtpBridgeheadServers
$LocalSiteInfo.PreferredRpcBridgeheadServers
$LocalSiteInfo.IntraSiteReplicationSchedule
# OR
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().Name
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().Domains
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().Subnets
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().Servers
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().AdjacentSites
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().SiteLinks
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().InterSiteTopologyGenerator
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().Options
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().Location
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().BridgeheadServers
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().PreferredSmtpBridgeheadServers
[System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]::GetComputerSite().PreferredRpcBridgeheadServers
