NAME
Count-ADObjectsInOU
SYNOPSIS
Retrieves a count of specified Active Directory objects
SYNTAX
Count-ADObjectsInOU [-Object] <String> [-BaseOU <String>]
[-StartingCountValue <Object>] [-EndingCountValue <Object>]
[-ShowOnlyCountValue <Object>] [<CommonParameters>]
DESCRIPTION
The "Count Active Directory Objects in an OU PowerShell Tool” utilizes the
"Get-ADObject" cmdlet and uses its filter parameter to target the
"ObjectCategory attribute. The objects that can be searched for are:
Computer, Group, Organizational Unit, and User. This tool retrieves the

count values of specified AD objects by using the mandatory “Object"
parameter. If you want to specify a certain OU that you would like to
count AD objects within, then you can use the “BaseOU" parameter. The
“BaseOU" parameter is used by the "Get-ADOjbect” cmdlet's “SearchBase"
parameter, so if there are multiple OUs as child objects within the
specified OU, a recursive search is done and count values will be
displayed for the specified AD object within those OUs as well. The
“Object" parameter is the only mandatory parameter and can be used by
itself to get all count values of specified AD ojbects within your domain
hierarchy. If you prefer to narrow the count values and just find AD
objects within a certain range of values, then you can use the
“StartingCountValue" and “EndingCountValue” range parameters. The
“StartingCountValue" and the “EndingCountValue" parameters cannot have the
same value, or an error will be displayed since, naturally, ranges do not
exist between the same number. The “StartingCountValue” and the
“EndingCountValue” also cannot have a value of “0”, or an error will be
displayed. The “EndingCountValue” parameter cannot be used without the
“StartingCountValue” parameter. However, the "StartignCountValue"
parameter can be used without the "EndingCountValue" to create a starting
point value to find the object count that is greater than or equal to the
"StartignCountValue" value. If the “BaseOU" parameter is used to define
which OU to search in, the script will first validate whether the
DistinguishedName value that is entered for the “BaseOU" parameter
actually exists before moving further in the script process. If a typo, or
non-existent OU is entered as the DistinguishedName for the “BaseOU"

parameter, an error will display. If you prefer to narrow the search down
even more and would like to search for one specific count value, then you
can use the “ShowOnlyCountValue” parameter. You may also use the
“ShowOnlyCountValue” parameter along with the two range parameters
(“StartingCountValue" and “EndingCountValue”). The “ShowOnlyCountValue”
parameter, unlike the two range parameters, can have a value of “0”.
