AD Infrastructure from No Man's Land View

There are people who knows why it happens, there are people who explain how to make it happen and there are people who use the above two concept for their own customization.

Suppose one day your manager asks to get over to the role of Active directory team lead. First question that comes to mind, is there any AD Infra documentation about it, In most case it is not. But with powershell by your side, it is simple to get these details. Lets start with Forest

 

$forest=[system.directoryservices.activedirectory.forest]::getcurrentforest()
write-host ""
Write-Host "Forest Mode :" $forest.Get_forestmode()
write-host ""
Write-Host SCHEMA ROLE OWNER
$forest.SchemaRoleOwner | select Name,Domain,IPAddress,sitename,OSVersion
if($forest.SchemaRoleOwner.IsGlobalCatalog()) {write-host $forest.SchemaRoleOwner.name is GC}
write-host ""
Write-Host NAMING ROLE OWNER
$forest.namingRoleOwner | select Name,Domain,IPAddress,sitename,OSVersion
if($forest.namingRoleOwner.IsGlobalCatalog()) {write-host $forest.namingroleowner.name is GC}
write-host ""
Write-host "SITES AND ITS LOCATION"
$forest.Sites | %{$_.name,$_.location}
Write-host "Number of sites "$forest.Sites.Count
#Global Catalogs
Write-host Number of GC : $forest.FindAllGlobalCatalogs().count
write-host ""
Write-Host "ALL GC'S NAME"
$forest.FindAllGlobalCatalogs() | %{$_.name}

OUTPUT:

Forest Mode : Windows2000Forest

That's all for this post. It is simple idea what you can idea from CMDlets without even going through all places collecting and documenting this information. SInce my test machine doesn't include multiple domains, I can really get hold of better formatting.
