  • Multiple computers applications
    2 Posts | Last post May 12, 2015
    • Is it possible to get list of installed application under one OU in active Directory.  I have 30 computers in One OU in Active Directory.  Needs to get list of all applications installed on those machines.
    • Anything is possible, however you will do the task in two different scripts.
      1) read the computer account names from the OU
      2) read the application lists from the servers
      
      There are already scripts that do both of these tasks if you search.
  • How do I

    • 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.
    • On the "create a profile" Suggestion, I get an error:
      PS C:\scripts> New-Item $PROFILE.CurrentUserAllHosts -ItemType File
      New-Item : Could not find a part of the path 'C:\Users\administrator\Documents\WindowsPowerShell\profile.ps1'.
      At line:1 char:9
      + New-Item <<<<  $PROFILE.CurrentUserAllHosts -ItemType File
          + CategoryInfo          : WriteError: (C:\Users\admini...ell\profile.ps1:String) [New-Item], DirectoryNotFoundException
          + FullyQualifiedErrorId : NewItemIOError,Microsoft.PowerShell.Commands.NewItemCommand
      
      It appears the first step should be "md WindowsPowerShell" (make a powershell directory under the folder for the profile you are trying to create).
    • FOUND IT! Okay, your function needs to be "loaded AS a function, and run as a function." It cannot be run as a standalone script. That was not made very clear. Maybe it should be obvious, but I'm just telling you that it is not clear that that is what is needed (maybe 'powershell [experts]' would already know that, but not 'normal mortal human beings'). That probably should have been THE first thing you mentioned. This is a very nice script offering! Thank you!
    • Well glad you got it worked out :)
      
      Enjoy.
  • Okay, I get "empty" output - nothing, nada, zilch

    • When I run your function, I get no output, not even the error about "no processes running." Also, on your note to another user you gave the wrong syntax, you said to use "Get-LoggedOnUser -ComputerName ServerName" - but you don't have a "-ComputerName" qualifier. Should be "Get-LoggedOnUser ServerName".
      Either way, from my "domain admin" PS prompt (so you know there's no permission issue), Get-WmiObject -class win32_process -ComputerName "RemoteServer" works perfectly! And yet, when I execute "Get-LoggedOnUser RemoteServer" - I get no errors, no messages, NO output whatsoever, from the exact same elevated (domain admin) session. What gives? I am on Server 2008 R2, with PS 2.0, full privs. Now, I did NOT "cut and paste" your script - I grabbed it via the "Download" button, in case there's a difference - maybe that's the issue? Maybe something wasn't corrected in the downloadable version? Haven't yet tested the 'cut-n-paste' version that is listed on the page here. Thanks.
    • I did some stub-testing: I placed a "Write-Host" just above the word 'function,' and that produces output just fine; but then, it's like, no matter what you enter as a parameter, it 'falls through' (bypasses) the entire function, and gives no output.
      So, what am I doing wrong? Basically, from within PS, I do: 
      .\Get-LoggedOnUser.ps1 RemoteServerName
      
  • just great

  • Only works for some remotes

    • 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.
  • Identify Idle Users

    • 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.

  • 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

    • 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.
