  • Only works for some remotes
    2 Posts | Last post February 11, 2014
    • Hi, I tested out your code and it works fine but for some computers, I can't tell who's logged on remotely.  Once I execute the "get-loggedonuser" command it will say "Cannot find any processes running" on a certain remote when I know a user is logged on remotely.  I'd appreciate some help in this matter.
      
      
      Thanks
    • You are querying a WMI NameSpace/Class for this information.
      
      You can test the raw cmdlets: 
      Get-wmiobject -namespace root\cimv2 -class win32_process -CN WS123
      
      By default the class requires you to have local admin rights to query.
      
      If you want you can use some other credentials:
      $cred = get-credential domain\user
      
      Then add the following to the get-wmiobject query:
       -credential $cred
      
      Let me know how you go.
      
      This used DCOM/RPC to query which requires a large range of network ports to connect, if you can use compmgmt.msc and connect to the remote machine, then you should have permission to connect with Get-wmiobject.
  • Big thanks Ben for a great tool.

    • I am just now beginning to understand Powershell. So see good examples of reall world usage really helps. I used both the loggedonuser and test-online scripts without issues. I can already see where this will be very helpful. I sure appreciate your sharing and the hellpful answers to other peoples questions were great too.
      Thanks,
      Johnny
    • Thanks for the feedback Johnny, I really appreciate it  :)
      
      Glad you find the tools useful.
      
      Hopefully they can inspire you to also also create tools for tasks that you commonly perform.

    • Hi first of all, thank you for that nice script!
      I currently using "query user /server" for those kind of jobs and i am looking for a way to do that via PS. So I found this nice one. Do you mean it is possible to check users, so i can see which of those are in status active or disconnected like in "user query"?
      
      Thanks,
      Mag
    • I prefer to use this module for those kinds of tasks, this has some very useful cmdlets: http://psterminalservices.codeplex.com/
      
      You gain the advantage of the results being PowerShell objects which makes customizing the output via the pipeline easier to achieve than .exe commands.

    • how to output results to csv not screen?

    • Get your script to permanently be loaded into PS? I have to load it every time I open powershell.
    • Hi Todd.
      The secret it to create a profile and then load it in the profile.
      E.g.
      New-Item $PROFILE.CurrentUserAllHosts -ItemType File
      
      Then open the file:
      E.g.
      notepad $PROFILE.CurrentUserAllHosts
      
      Then add the dot source in that script to load the function.
      E.g.
      . c:\fullpath\Get-LoggedOnUser.ps1
      
      Then save and close the file, the next time you open powershell that script will run and the function will be available for you to call.
  • The same - no output from the script

    • Hi!!
      When I running this script on Windows 8 Pro against two remote Windows 2003 servers, there is no aoutput at all from the script...I've followed your recomendation  (running powershell as admin, used . . c:\fullpath\Get-LoggedOnUser.ps1) but it seem that function didn't loaded at all... What do you think?
    • just use the single dot, then space to wherever you downloaded the script to.
      . c:\fullpath\Get-LoggedOnUser.ps1
      After that it should be in memory.
  • What does this error mean
    2 Posts | Last post January 20, 2013
    • Hi I used this script along with TEST-ONLINE script but for most of the machines i see the below error. can you please help.
      
      Checking Users . . .
      VERBOSE: Online : cg000164578
      Cannot find any processes running on cg000164578
      VERBOSE: Online : fh00024990
      Cannot find any processes running on fh00024990\
      
      I checked both the machine and OS was Windows XP Professional-sp2
      
      Overall its a excellent script!!!
    • Hi iis4313,
      
      It seems like either you do not have permission to run the wmi query against the remote machine OR there is a problem with wmi on the remote machine.
      
      The actual query that is failing is:
      Get-WmiObject -class win32_process -ComputerName "cg000164578"
      So if you run that you will get your error.
      
      In General you need to be a local administrator on a machine to run the query.
  • No Output

    • I am getting no output from this script at all.  I have no clue what I am doing wrong.
    • Hi Dave, try this.
      step 1) Download the file and save it to a known location.
      step 2) Open the powershell console (running as Administrator/elevated)
      step 3) dot source the file/function into memory:
      . c:\fullpath\Get-LoggedOnUsers.ps1
      That is dot, then a space, then the full path to the file, then press enter.
      step 4) see if the function is loaded: Get-item function:\Get-LoggedOnUsers
      step 5) call the function via: Get-LoggedOnUsers -computername server123
    • sorry it should be Get-LoggedOnUser not Get-LoggedOnUsers notice the singular.
  • Is there any way to change the timeout ?
    5 Posts | Last post August 18, 2012
    • I'm using this script with "get-content xxxx.txt" and it works fine...
      The only thing is that I have around 2k pc to parse...
      so when they are offline it takes a while before I get the "Cannot find processes..."
      
      I was wondering if there is anyway to put a timeout to search in xxx milliseconds ?
      
      Thanks for your help !
    • Sure thing, I wrote this function called Test-Online.
      If you install that you can use it as part of the pipeline along the way.
      Download here:
      http://gallery.technet.microsoft.com/scriptcenter/2789c120-48cc-489b-8d61-c1602e954b24
      
      Then you can go: 
      Import-Csv -Path C:\ps\computers.csv | Test-Online | Get-LoggedOnUser
      OR
      get-content -Path C:\ps\computers.csv | Test-Online | Get-LoggedOnUser
      
      LOVE that pipeline. Let me know how you go?
    • WONDERFULL !!! thanks alot :)
    • Help again :)
      I'm trying to pipe "Get-ADComputer -Filter * -Property * | Format-Table Name" this way :
      $CptList = Get-ADComputer -Filter * -Property * | Format-Table Name -autosize
      $Cptlist | Out-String | Test-Online | Get-LoggedOnUser
      
      But I get that 0 Computers online... (I think it doesn't like the variable format... can you help me out ?
    • Wen you use Format-Table you kill the object and it can never be consumed anywhere else. so saving to a variable is not very useful, since any format command it really only useful to view the output on the screen.
      
      So try to use Select-Object instead of Format-Table (the results on the screen look similar, however under the covers Select-Object is far more useful).
      
      So anywhere there are a couple of ways to do this:
      
      1) Use expandproperty to get one property Name into a simple list. 
      $ComputerList = Get-ADComputer -Filter * -Property * | Select-Object -ExpandProperty Name
      
      Then: $ComputerList | Test-Online | Get-LoggedOnUser

    • Thanks for the script, it works great. How can i use to check PCs from a file.
      
      I tried 
      Get-LoggedOnUser -ComputerName c:\pcs.txt
       but it failed :)
    • You were close, however the ComputerName expects a string array. To get this you need to use the get-content cmdlet first to get the contents of the file (one computer per line). The end result will be: Get-LoggedOnUse​r -ComputerName (get-content c:\pcs.txt)
