Add Computer to Group using Add-ADGroupMember

Add-AdGroupMember cmdlet adds one or more users, computers, groups, or services accounts in active directory groups. You can use Add-AdGroupMember to add a computer to a group or security group.

In this article, I will explain how to use the Add-AdGroupMember cmdlet to add a computer to ad group, add computers to a group from CSV with PowerShell.

Add Computer to Group

To add a computer to a group, use Add-ADGroupMember cmdlet. You will need to specify the computer name and group name in the Add-ADGroupMember cmdlet.

Syntax and script to add a computer to ad group as below

ADD-ADGroupMember -identity <group name> –members <SAMAccount name $>
ADD-ADGroupMember -identity "RDPEnabled" –members "INCORP-AS-101$"

In the above PowerShell script to add a computer to a group, it adds a computer named INCORP-AS-101 to a group RDPEnabled.

Note in the above script, we have added $ at the end of a computer. $ refers to SAMAccountName on the computer name.

If you don’t specify SAMAccountName $ at the end of the computer and instead use script as below

ADD-ADGroupMember -identity "RDPEnabled" –members "INCORP-AS-101"

It will throw an error message as

Add-AdGroupmember : Cannot find an object with identity: 'INCORP-AS-101' under:

You can use the above PowerShell script having SAMAccountName of a computer to add a computer to a security group in the active directory using Add-AdGroupMember cmdlet in PowerShell.

Add Computers to Group from CSV

You can use the Add-AdGroupMember cmdlet in PowerShell to add computers to the group from a CSV file.

Let’s consider an example, you have computer account names in a CSV file. You want to read the computer name from the CSV file and add a computer to a group.

Use the below script to add computers to ad group from CSV using Add-AdGroupMember and Get-AdComputer cmdlet

$SecurityGroupname = "ITIS_SECURITY"

$ComputerList = Get-Content "D:\PowerShell\ComputerList.csv"

foreach ($Computer in $ComputerList)
       Add-AdGroupmember -Identity $SecurityGroupname  -Members (Get-ADComputer $computer)

In the above PowerShell script to add a computer to a security group,

$SecurityGroupname variable stores security active directory group name.

$ComputerList variable stores computer name retrieved using Get-Content cmdlet.

Using the Foreach loop, it iterates over each computer and passes the computer object to the Add-AdGroupMember cmdlet.

Add-AdGroupMember cmdlet uses Identity parameter to specify group name and members parameter to specify computer object. We have used the Get-AdComputer cmdlet to get ad computer from an active directory.

The above script will add computers to the group from a CSV file.

I hope the above article on how to add a computer to a group using the Add-AdGroupMember cmdlet is useful to you.
