For the next couple of posts I’ll be looking into AD security and auditing. In this article we’ll look at how to use Get-ADUser to list all recently created accounts.
With the increasing number of cyber attacks, security is at the top of most IT departments agenda. There are many checks you can perform to make sure AD is safe and secure, and that only valid or approved modifications have been made to user accounts. I’ll look at AD auditing in a future post, but this will be a handy snippet of PowerShell to help you identify recently created AD accounts, and a bonus bit of code to identify recently modified accounts!
I’ve been working on a simple PowerShell command today to import into our endpoint management solution so we can alert on disks with low diskspace. It’s been a while since I’ve dabbled with PowerShell, and it reminded me just how flexible it is and much I love it!
So I thought I would walk you through the evolution of the command I ended up with.
In this article we’ll look at using Get-ADComputer and Set-ADComputer to list computer accounts which haven’t logged in for xx days, and then automatically disable them.
In part 1 we looked at how to use Get-ADComputer to list computers by name and sort them by their last logon date with the premise that we can use the information to remove historic computer accounts from the domain.
Now we know the computer accounts we want to work with we will look at modifying the PowerShell command to automatically disable them.
I’ve written about Get-ADUser several times already to find out Active Directory user information, but in this post we’ll be using Get-ADComputer to find out the last logon date for the computers in Active Directory.
As computers are retired or fail and are replaced how often do admins remember to remove the computer accounts from Active Directory?
You can use the command we are going to create below to enumerate the last login date for all the computer accounts in your domain, so that you can safely disable and remove them after they have been inactive for a period of time. Continue reading →
