Get last logon time,computer and username together with Powershell

I have a script which gets the last logon times of each computer in the domain.

My script:

$dcs = Get-ADComputer -Filter { OperatingSystem -NotLike '*Server*' } -Properties OperatingSystem
foreach($dc in $dcs) { Get-ADComputer $dc.Name -Properties lastlogontimestamp | Select-Object @{n="Computer";e={$_.Name}}, @{Name="Lastlogon"; Expression={[DateTime]::FromFileTime($_.lastLogonTimestamp)}}
}

==================================

Result:

Computer Lastlogon
-------- ---------
DC1 6/06/2013 16:38:24
DC2 6/06/2013 16:30:40

=============================================

I also want to get who/which account made this logon. For example:

Computer Lastlogon User
-------- ------------------ ----
DC1 6/06/2013 16:38:24 user2
DC2 6/06/2013 16:30:40 user1

This one might not be perfect but it will get you on the right track. To get the exact last user, please see this script. It will give you further information on how to filter the exact last user. In the below example, I have used, select-object -First 1 which should be a pretty good indicator of the last logged on user. To get the last logged on user, you need to use

Get-WmiObject -Class Win32_UserProfile

To 'join' the Get-ADComputer and Get-WMIObject information, I have used a Hash Table.

If you are running this from a Domain Administrator account, you can take the -credential $credential part out. Otherwise, leave it in and you can run it from a normal workstation with the RSAT tools installed so Get-ADComputer is available.

Code below:

$computers = Get-ADComputer -Filter { OperatingSystem -NotLike '*Server*' } -Properties OperatingSystem
$credential = Get-Credential -Message "Please enter your administrator username and password"
foreach($computer in $computers) { $pcinfo = Get-ADComputer $computer.Name -Properties lastlogontimestamp | ` Select-Object @{Name="Computer";Expression={$_.Name}}, ` @{Name="Lastlogon";Expression={[DateTime]::FromFileTime($_.lastLogonTimestamp)}} $lastuserlogoninfo = Get-WmiObject -Class Win32_UserProfile -ComputerName $computer.name -Credential $credential | Select-Object -First 1 $SecIdentifier = New-Object System.Security.Principal.SecurityIdentifier($lastuserlogoninfo.SID) $username = $SecIdentifier.Translate([System.Security.Principal.NTAccount]) # Create hashtable for properties $properties = @{'Computer'=$pcinfo.Computer; 'LastLogon'=$pcinfo.Lastlogon; 'User'=$username.value } #end $properties write-output (New-Object -Typename PSObject -Property $properties)
}

Check the formatting when you use it. Some of it I had to add in an escape (`) character to fit it into the script window.

Thanks, Tim.

Not to burst everyone's bubble, but the "LastUseTime" field under Win32_UserProfile is NOT last Login; it's simply the last timestamp the "Profile" was updated (for any reason). You will find ALL profiles updated periodically for various reasons--installers, policy updates, etc.

Also, the data is not ordered by default, so the "-First 1" argument is not useful unless the data is first sorted by "LastUseTime"--which again is worthless due to above.

I hate to say that the above scripts are not providing any useful data for "Last Logon".

This is Tim's Code and I updated it in order to display computer ip address & operating system, and export data.

 $computers = Get-ADComputer -Filter { OperatingSystem -NotLike '*Server*'} -Properties OperatingSystem foreach($computer in $computers) { $pcinfo = Get-ADComputer $computer.Name -Properties ipv4Address, OperatingSystem ,lastlogontimestamp | Select-Object @{n="Computer";e={$_.Name}}, @{Name="Lastlogon";Expression={[DateTime]::FromFileTime($_.lastLogonTimestamp)}},ipv4Address,OperatingSystem $lastuserlogoninfo = Get-WmiObject -Class Win32_UserProfile -ComputerName $computer.name -Credential $credential | Select-Object -First 1 $SecIdentifier = New-Object System.Security.Principal.SecurityIdentifier($lastuserlogoninfo.SID) $username = $SecIdentifier.Translate([System.Security.Principal.NTAccount]) # Create hashtable for properties $properties = @{'Computer'=$pcinfo.Computer; 'LastLogon'=$pcinfo.Lastlogon; 'ipv4Address'=$pcinfo.ipv4Address; 'OperatingSystem'=$pcinfo.OperatingSystem 'User'=$username.value } #end $properties write-output (New-Object -Typename PSObject -Property $properties) | export-csv .\Computers.csv -append -notypeinformation -encoding "unicode" }
