User Logon/Logoff Information using Powershell

Question

I want to be able to check a remote computer's user logon/logoff sessions and times and I have the following code that I got from stackoverflow, but I cannot figure out how to tell the script to check a remote computer:

$UserProperty = @{n="User";e={(New-Object System.Security.Principal.SecurityIdentifier  
$_.ReplacementStrings[1]).Translate([System.Security.Principal.NTAccount])}}
$TypeProperty = @{n="Action";e={if($_.EventID -eq 7001) {"Logon"} else {"Logoff"}}}
$TimeProeprty = @{n="Time";e={$_.TimeGenerated}}

Get-EventLog System -Source Microsoft-Windows-Winlogon | select $UserProperty,$TypeProperty,$TimeProeprty

I did do throw in a $Computername variable and a Foreach loop statment like in the following to try and get it to run on a remote computer, but it keeps checking the local system that I am on, not the remote system:

$Computername = Read-Host "Enter Computername Here"

Foreach $Computer in $Computername

    {
        $UserProperty = @{n="User";e={(New-Object System.Security.Principal.SecurityIdentifier $_.ReplacementStrings[1]).Translate([System.Security.Principal.NTAccount])}}
        $TypeProperty = @{n="Action";e={if($_.EventID -eq 7001) {"Logon"} else {"Logoff"}}}
        $TimeProeprty = @{n="Time";e={$_.TimeGenerated}}

        Get-EventLog System -Source Microsoft-Windows-Winlogon | select $UserProperty,$TypeProperty,$TimeProeprty
    }

Answer 1

I know this is an old question, but no answer was ever accepted. One of the problems is that the script doesn't show which machine the user was logged into. Anyway, I fixed it up (including the typo).

Get-LogonHistory.ps1:

param(
    [alias("CN")]
    $ComputerName="localhost"
)

$UserProperty = @{n="User";e={(New-Object System.Security.Principal.SecurityIdentifier $_.ReplacementStrings[1]).Translate([System.Security.Principal.NTAccount])}}
$TypeProperty = @{n="Action";e={if($_.EventID -eq 7001) {"Logon"} else {"Logoff"}}}
$TimeProperty = @{n="Time";e={$_.TimeGenerated}}
$MachineNameProperty = @{n="MachinenName";e={$_.MachineName}}

foreach ($computer in $ComputerName) {
    Get-EventLog System -Source Microsoft-Windows-Winlogon -ComputerName $computer | select $UserProperty,$TypeProperty,$TimeProperty,$MachineNameProperty
}

With this, it will show which machine the user logged into. Multiple remote computers can be passed into the command line with commas between each (no spaces).
