How to List All Logged-in Users on Windows Servers Using PowerShell

Managing user accounts on multiple Windows servers can be a daunting task, especially when you need to generate a list of logged-in users. If you’re looking for a straightforward solution to automate this process, you’ve come to the right place! In this guide, we’ll explore how to use PowerShell effectively to list all the folders in C:\Users from a list of servers, providing you not only with the necessary commands but also tips for troubleshooting.

The Challenge

You want to create a list of all the users logged into your Windows servers. To do this, you are leveraging PowerShell commands to retrieve data from a CSV file containing server names. However, you encountered an error when running your initial script, which stated:

This can happen for several reasons including issues with how the server names are formatted or how they are referenced in your script.

Breaking Down the Solution

To resolve these problems and create an effective PowerShell script, let’s go through the solution step by step:

Step 1: Importing the CSV File

First, you need to ensure that your CSV file is set up correctly. Make sure it contains appropriate headers for the server names. For example, the CSV should look like this:

Step 2: Iterating Through Each Server

You will need to loop through each server listed in your CSV file. This is done using a foreach statement. Here's how it looks in practice:

Step 3: Output the Results

One of the issues you faced was how to display the user directory data correctly. Instead of using Write-Host, which only outputs strings, you should use Format-Table for a more readable format. This will print the results in a nicely organized table.

Troubleshooting Tips

If you continue to face the same error, consider these troubleshooting methods:

Check Server Names: Ensure that the server names in your CSV file are correctly spelled and formatted, paying attention to cases and whitespace.

Permissions: Make sure your PowerShell session has the necessary permissions to invoke commands on the specified servers. Your account should have administrative privileges on all target servers.

Network Connectivity: Verify that there is network connectivity between your management workstation and the servers you are trying to access.

Conclusion

Automating the retrieval of logged-in users from multiple Windows servers can save you a lot of time and hassle. By following the steps outlined above, you should now be able to create a list of user directories effectively using PowerShell. With the right commands and format, you’ll have an easily manageable output ready for further processing, such as writing to a file.
