I need a PS script to retrieve a list of computers (from AD) and the user last logged on to every PC.
Is that possible with PS?
In a roundabout way, yes it is possible. It's not as straightforward as pulling the information from SCCM so if you have that, that's the easier option, as the information is already in the SCCM database.
To achieve something similar in PowerShell, you have two tasks. First you'll need to generate the list of computers. You can do this with the Active Directory module and Get-ADComputer. The Active Directory module will be on your Domain Controller or, ideally, you'll be using it on a computer that has RSAT installed.
You should use Get-Help to figure out exactly what you need to do, but a basic list of computers could be produced with
Get-ADComputer -filter * | Select-Object -ExpandProperty Name | Out-File C:\computers.txt -append -noclobber
Now that you have a list of all the computers in your Active Directory you can use a WMI query to find out who is logged on. The current logged in user can be found in the username property of Win32_ComputerSystem.
You can use foreach to loop over all the computers in the computers.txt file and run
Get-WMIObject Win32_computersystem -computerName $computer | Select-Object UserName
I hope I've given you enough information to make a start on a script.
What you are asking is quite troublesome to accomplish. This is because you need to enable security auditing on the system.
Don Jones also pointed this out in the following forum comment: LINK
Maybe that forum topic gives you some pointers to look for.
Agree with Matt., a task like that is really better suited to a product such as SCCM. It can retrieve the information for you immediately.
From an inventory point of view, Active Directory discovery is one of the main mechanisms SCCM can use for identifying computers, and getting the details of a WMI class is easily done via the hardware inventory.
If you just need it for finding out who is logging onto a computer, then a logon script that writes the information to a text file is maybe an idea.
Hi Team-Hopes The bellow Code will meet the requirements.
Get-AdComputer -Filter * -Properties Description|Select -Expand Name,Description|Export-Csv
Get-AdComputer -Filter * -Properties Description|Select -Expand Name,Description|Convertto-Html|Out-File
Kindly Correct If anyMistakes...
