Get-ADComputer -Filter - powershell

Question

I have a script that uploads data about a PC with the last activity more than 100 days, I can’t upload it as a normal table and I don’t understand how to add 2 distributionname + description fields
Get-ADComputer -Filter * -Properties OperatingSystem, LastLogonDate | Where { $_.LastLogonDate -LT (Get-Date).AddDays(-100) } | Select-Object Name, OperatingSystem, LastLogonDate | Out-File "\\Client\C$\Users\computer_ad.csv" -encoding Unicode -Delimiter ";"

Answer 1

You should not use Out-File to save as CSV. There is a special cmdlet for that called Export-Csv
Also, it is better to set the reference date to midnight using .Date when comparing to the LastLogonDate.
By default, Get-ADComputer returns these properties:
DistinguishedName, DNSHostName, Enabled, Name, ObjectClass, ObjectGUID, SamAccountName, SID, UserPrincipalName and for anything on top of that you need to specify it in the -Properties parameter.
As for attribute Description, that's easy enough, but what do you mean by distributionname ??
I'm guessing you want the DistinguishedName name there:
$refDate = (Get-Date).AddDays(-100).Date # set this to midnight
Get-ADComputer -Filter * -Properties OperatingSystem, LastLogonDate, Description |
Where-Object { $_.LastLogonDate -lt $refDate } |
Select-Object Name, OperatingSystem, LastLogonDate, Description, DistinguishedName |
Export-Csv -Path "\\Client\C$\Users\computer_ad.csv" -Delimiter ';' -NoTypeInformation
If you really want the file to be encoded in UTF16-LE (Unicode), you can add that to the Export-Csv line: -Encoding Unicode, although UTF8 is more commonly used.
