Count your Active directory objects

When installing AADConnect you need to size your server according to this table:

Hardware requirements for Azure AD Connect

The following table shows the minimum requirements for the Azure AD Connect sync computer.

To quickly count all objects in your Active Directory do this:

1|	(Get-ADObject -SearchBase "dc=Mydomain,dc=com" -LDAPFilter "(objectCategory=*)").Count

This will show all objects.

If you want to know how many user, group, computer account, distribution group and security group objects there are do this:

1| 2| 3| 4| 5| 6| 7|

$ADUser = (Get-AdUser -Filter *).Count $ADGroup = (Get-ADGroup -Filter *).Count $ADComputer = (Get-ADComputer -Filter *).Count $Distribution_Groups = (Get-ADGroup -Filter {GroupCategory -eq "Distribution"}).count $Security_Groups = (Get-ADGroup -Filter {GroupCategory -eq "Security"}).count $ADObjects = $ADUser + $ADGroup + $ADComputer + $Distribution_Groups + $Security_Groups $ADObjects
