Filtering get-adobject with Powershell - powershell

Question

Could some one tell me the issues with the query.
I want to pull back all the users that are not in a number of specific OU, I thought the following query would work, but as you can see it pulls back a user with "ou=staff" in the DN (extracted from all of the output).
I am trying to say if non of the following appear in the DN attribute.
$NotinDirectory = Get-ADObject -LDAPFilter "objectClass=person" -SearchBase "OU=Accounts,DC=Company,DC=ac,DC=uk" -Properties ou |? {($_.DistinguishedName -notlike "*Agency*" -and "*Contractors*" -and "*Fellows*" -and "*Visitors*" -and "*ou=Staff*" -and "*Contacts*")}
CN=jo blogs,OU=Staff,OU=Accounts,DC=compnay,DC=ac,DC=uk
UPDATE
so I tried this based on comments bellow
$NotinDirectory = Get-ADObject -LDAPFilter "objectClass=person" -SearchBase "OU=Accounts,OU=iah,DC=iah,DC=ac,DC=uk" | ? {($_DistinguishedName -notlike "*Agency*" -and $_DistinguishedName -notlike "*Contractors*" -and $_DistinguishedName -notlike "*Fellows*" ) -and ($_DistinguishedName -notlike"*Visitors*") -and ($_DistinguishedName -notlike"*OU=Staff*" -and $_DistinguishedName -notlike"*Contacts*")}
foreach ($test in $NotinDirectory){ Write-Host $test.DistinguishedName}
but i still get
CN=xxx xxxxx,OU=Staff,OU=Accounts,DC=company,DC=ac,DC=uk

Answer 1

In your Where-Object filter:
($_.DistinguishedName -notlike "*Agency*" -and "*Contractors*" -and "*Fellows*" -and "*Visitors*" -and "*ou=Staff*" -and "*Contacts*")
you only compare $_.DistinguishedName to a string once, the first time (-notlike "*Agency*").
It will be parsed as follows:
(($_.DistinguishedName -notlike "*Agency*") -and ("*Contractors*") -and ("*Fellows*") -and ("*Visitors*") -and ("*ou=Staff*") -and ("*Contacts*"))
(($_.DistinguishedName -notlike "*Agency*") -and $true -and $true -and $true -and $true -and $true)
($_.DistinguishedName -notlike "*Agency*")
You'll have to do:
Get-ADObject | Where-Object {($_.DistinguishedName -notlike "*Agency*" -and
$_.DistinguishedName -notlike "*Contractors*" -and
$_.DistinguishedName -notlike "*Fellows*" -and
$_.DistinguishedName -notlike "*Visitors*" -and
$_.DistinguishedName -notlike "*ou=Staff*" -and
$_.DistinguishedName -notlike "*Contacts*")}
in order to test for all 6 strings.
If you have a variable number of strings you want to exclude, you can use ForEach-Object inside Where-Object:
$Excludes = "*Agency*","*Contractors*","*Fellows*","*Visitors*","*ou=Staff*","*Contacts*"
Get-ADObject |Where-Object {
$ADObj = $_
#($Excludes |ForEach-Object {
$ADObj.DistinguishedName -notlike $_
}) -notcontains $false
}
