PowerShell to find remote logins

I need a powershell script which I can run against a list of PCs (Windows 7) and save the output to csv/excel.

I've done some searching and found the code below provides the raw data i need (but now need to get this data from multiple PCs and get the output to a file)

E.g. of PowelShell script:
             
$IDs = @(
                    "1024"
                )
Get-WinEvent -ComputerName IS-020115-RL -logname "Microsoft-Windows-TerminalServices-RDPClient/Operational" | Select MachineName,Message,User,TimeCreated,SourceIP,Id | Where-Object {($IDs -contains $_.id)}

E.g. of screen output:

MachineName : IS-020115-RL.internal.thewinesociety.com
Message     : RDP ClientActiveX is trying to connect to the server (Sophos)
User        :
TimeCreated : 09/06/2016 17:03:40
SourceIP    :
Id          : 1024

The specific info I need are the remote computer name "Sophos" in the above and TimeCreated.  I'm really under time pressure so am looking for the 'complete' script not hints please.

I presume you need the remote computer in message as a separate property in the output and the script should run against multiple computers.. If yes, Try following code..
GC C:\Computers.txt | % {
	Write-Host "Working on $_"
	Get-WinEvent -ComputerName $_ -FilterHashTable @{LogName="Microsoft-Windows-TerminalServices-RDPClient/Operational";ID=1024} | 
	Select *,@{N="RemoteComp";E={$_.Properties[1].Value}}
}| Select MachineName,Message,TimeCreated,Id,RemoteComp | 
Export-csv C:\temp\report.csv -nti

Open in new window

You can place the computers you want to search In the input file..
Computers.txt format.
ComputerA
ComputerB
ComputerC

Open in new window

Hi Subsun
Thanks I just trying this now - a couple of questions.  
If the remote PC has never RDP'd into another PC/Server will the output file list the computer name then NUL / so you know its been queried but no results found?
Is it possible to constrain the log to just the last 90 days?
Thanks

Change line 3 to following to get last 90 days logs..
Get-WinEvent -ComputerName $_ -FilterHashTable @{LogName="Microsoft-Windows-TerminalServices-RDPClient/Operational";StartTime=(get-date).AddDays(-90);ID=1024} | 

Open in new window


Script will read the RemoteComp property value from the message part of the event, if the server is not listed in event message then the result will be null.
and if there is no 1024 event, Then you may get error No events were found that match the specified selection criteria...

Hi Subsun

I have run this now, it works well but i wonder if its possible to capture the error
"Get-WinEvent : The RPC server is unavailable" on the output file.  

My understanding is, I get this error because the computer its querying is off.  As I'm running against 100s of machines if the error was output to file it would make it much easier to power on the machines, and run run against just those that were missed.

Thanks again

You can use the Try/Catch for error handling..
GC C:\Computers.txt | % {
$comp = $_
	Write-Host "Working on $comp"
	Try{Get-WinEvent -ComputerName $comp -FilterHashTable @{LogName="Microsoft-Windows-TerminalServices-RDPClient/Operational";ID=1024} -ea 1 | 
	Select *,@{N="RemoteComp";E={$_.Properties[1].Value}}
	}Catch{
	$_.Exception.Message | Select @{N="MachineName";E={$comp}},@{N="Message";E={$_}},TimeCreated,Id,RemoteComp
	}
}| Select MachineName,Message,TimeCreated,Id,RemoteComp | 
Export-csv C:\temp\report.csv -nti
