The system requirements for Exchange Server 2013 include the following for Active Directory:
- Forest and domain functional level of Windows Server 2003 or higher (up to Windows Server 2012 R2 is supported with Exchange Server 2013 SP1 or later)
- Schema Master running Windows Server 2003 SP2 or later
- At least one global catalog server in each Active Directory site where Exchange 2013 will be installed that runs Windows Server 2003 SP2 or higher
Using PowerShell we can retrieve all of this information quickly.
Here is a quick and dirty script I wrote that breaks a whole lot of PowerShell “rules” but gets the job done. I’ll probably try and improve it in the near future, but for now it gets me the information I need, which is all I really need any script to do.
Import-Module ActiveDirectory
$forest = Get-ADForest
Write-Host ""
Write-Host -ForeGroundColor Yellow "*** Forest: $($forest.RootDomain) ***"
Write-Host ""
Write-Host "Forest Mode: $($forest.ForestMode)"
Write-Host "Schema Master: $($forest.SchemaMaster)"
$domains = @($forest | Select -ExpandProperty:Domains)
Foreach ($domain in $domains)
{
Write-Host ""
Write-Host -ForeGroundColor Yellow "*** Domain: $domain ***"
Write-Host ""
$domaindetails = Get-ADDomain $domain
Write-Host "Domain Mode: $($domaindetails.DomainMode)"
Write-Host "PDC Emulator: $($domaindetails.PDCEmulator)"
Write-Host "Infrastructure Master: $($domaindetails.InfrastructureMaster)"
Write-Host "RID Master: $($domaindetails.RIDMaster)"
}
$domaincontrollers = @(Get-ADDomainController -Filter {IsGlobalCatalog -eq $true})
$gcs = $domaincontrollers | Group-Object -Property:Site,OperatingSystem | Select @{Expression="Name";Label="Site, OS"},Count | Sort Name
Write-Host ""
Write-Host -ForeGroundColor Yellow "*** Global Catalogs by Site/OS ***"
$gcs | ft -auto
The script requires the ActiveDirectory PowerShell module, and in a multi-domain forest should be run in the forest root domain with an admin account that can access each domain.
Example output:
