I just have a small issue, not really an issue though... When searching computeraccounts in AD it gives me only 1000 records, is it possible to counter this limit? Regards Hi Niklas,

I have tried: -Domain test.com OU group1 -computers AllComputers -ToCsv test.csv but all it returns is the OU information. I have also tried to run the following: -Domain test.com -computers AllComputers -CustomAll "(&(ObjectCategory=OU)(OU=group1))" This too returns values on all objects in the domain, not just the OU.

here’s an example:

PS > $user = .\Get-AD.ps1 -Domain powershell.nu -User nigo -Filter sAMAccountName -ToObject
PS > $user

distinguishedName : {CN=Niklas Goude,CN=Users,DC=POWERSHELL,DC=NU}
