How to Query a MAC Address in SCCM

In System Center Configuration Manager (SCCM), setting the OSDComputerName variable is crucial during the Operating System Deployment (OSD) process. One common approach is to use PowerShell scripts to achieve this. In this article, we will explore how to query a MAC address using SCCM and provide two solutions for setting the OSDComputerName variable.

PowerShell Function

To begin with, let's create a PowerShell function that fills the Task Sequence step. This function sets the OSDComputerName variable using a script generated by another PowerShell script. The code is as follows:

```powershell

function Set-OSDComputerName {

param ($serialNumber)

$osdComputerName = Get-SCCMComputerName -SerialNumber $serialNumber

$osdComputerName

}

```

Modifying the Task Sequence Step

To use this PowerShell code in your Task Sequence, you'll need to download and import it. Once imported, you can use the code by adding a new step to your Task Sequence.

Here's an example of how to modify the Task Sequence step using PowerShell:

1. Add a new step to your Task Sequence.

2. Select 'Run PowerShell script' as the step type.

3. In the 'Script' field, enter the following code:

```powershell

Set-OSDComputerName -SerialNumber

```

Replace `` with the actual serial number of the computer.

Solution 1: Static List

In this solution, you'll create a static list of computers with their corresponding serial numbers and names. This list will be used to set the OSDComputerName variable.

To achieve this:

1. Create a new PowerShell script that contains a hardcoded list of computers with their serial numbers and names.

2. Use the `Set-OSDComputerName` function to set the OSDComputerName variable based on the serial number.

Solution 2: Dynamic

In this solution, you'll use the SCCM Administration Service (REST API) to get the computer name dynamically. This approach is more flexible and scalable than Solution 1.

To achieve this:

1. Create a new PowerShell script that uses the SCCM Administration Service REST API to retrieve the computer name based on the serial number.

2. Use the `Set-OSDComputerName` function to set the OSDComputerName variable based on the retrieved computer name.

In conclusion, setting the OSDComputerName variable during OSD is a crucial step in SCCM. By using PowerShell scripts and the SCCM Administration Service (REST API), you can create dynamic solutions that support both CMG installation and on-premise installation. Whether you choose Solution 1 or Solution 2, make sure to modify the code to match your environment.

Additional Information

The SCCM Administration Service supports connections through the Cloud Management Gateway (CMG). This means you can use this solution even if you have a CMG setup in your environment.

By combining these two solutions, you can create a more robust and scalable approach for setting the OSDComputerName variable.
