You add a new computer directly to the Microsoft System Center Configuration Manager 2007 database by calling the ImportMachineEntry Method in Class SMS_Site. This can be used to deploy operating systems to computers that have not yet been discovered automatically by Configuration Manager 2007.

You must provide the following information:

The MAC address must be for a network adapter that has a driver in Windows PE. The MAC address must be in colon format. For example, 00:00:00:00:00:00. Other formats will prevent the client from receiving policy.

You should add a newly imported computer to a collection. This allows you to immediately create advertisements for deploying operating systems to the computer.

You can associate a new computer with a reference computer. For more information, see How to Create an Association Between Two Computers in Configuration Manager.

To add a new computer

  1. Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.

  2. Call the ImportMachineEntry Method in Class SMS_Site.

  3. Add the resource identifier you get from ImportMachineEntry to a collection.


The following example method adds a new computer to Configuration Manager. The ImportMachineEntry Method in Class SMS_Site is used to import the computer. Then, the computer is added to the "All Systems" collection.

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

Visual Basic Script  Copy Code
Sub AddNewComputer (connection, netBiosName, smBiosGuid, macAddress)

	Dim inParams
	Dim outParams
	Dim siteClass
	Dim collection
	Dim collectionRule

	If (IsNull(smBiosGuid) = True) And (IsNull(macAddress) = True) Then
		WScript.Echo "smBiosGuid or macAddress must be defined"
		Exit Sub
	End If	 

	If IsNull(macAddress) = False Then
		macAddress = Replace(macAddress,"-",":")
	End If

	' Obtain an InParameters object specific
	' to the method.

	Set siteClass = connection.Get("SMS_Site")
	Set inParams = siteClass.Methods_("ImportMachineEntry"). _

	' Add the input parameters.
	inParams.Properties_.Item("MACAddress") =  macAddress
	inParams.Properties_.Item("NetbiosName") =  netBiosName
	inParams.Properties_.Item("OverwriteExistingRecord") =  False
	inParams.Properties_.Item("SMBIOSGUID") =  smBiosGuid

	' Add the computer.
	Set outParams = connection.ExecMethod("SMS_Site", "ImportMachineEntry", inParams)

   ' Add the computer to the all systems collection.
   set collection = connection.Get("SMS_Collection.CollectionID='SMS00001'")
   set collectionRule=connection.Get("SMS_CollectionRuleDirect").SpawnInstance_
   collectionRule.ResourceID= outParams.ResourceID
   collection.AddMembershipRule collectionRule

End Sub
C#  Copy Code
public int AddNewComputer(
	WqlConnectionManager connection, 
	string netBiosName, 
	string smBiosGuid, 
	string macAddress)
		if (smBiosGuid == null && macAddress == null)
			throw new ArgumentNullException("smBiosGuid or macAddress must be defined");

		// Reformat macAddress to : separator.
		if (string.IsNullOrEmpty(macAddress) == false)
			macAddress = macAddress.Replace("-", ":");

		// Create the computer.
		Dictionary<string, object> inParams = new Dictionary<string, object>();
		inParams.Add("NetbiosName", netBiosName);
		inParams.Add("SMBIOSGUID", smBiosGuid);
		inParams.Add("MACAddress", macAddress);
		inParams.Add("OverwriteExistingRecord", false);

		IResultObject outParams = connection.ExecuteMethod(

		// Add to All System collection.
		IResultObject collection = connection.GetInstance("SMS_Collection.collectionId='SMS00001'");
		IResultObject collectionRule = connection.CreateEmbeddedObjectInstance("SMS_CollectionRuleDirect");
		collectionRule["ResourceClassName"].StringValue = "SMS_R_System";
		collectionRule["ResourceID"].IntegerValue = outParams["ResourceID"].IntegerValue;

		Dictionary<string, object> inParams2 = new Dictionary<string, object>();
		inParams2.Add("collectionRule", collectionRule);

		collection.ExecuteMethod("AddMembershipRule", inParams2);

		return outParams["ResourceID"].IntegerValue;
	catch (SmsException e)
		Console.WriteLine("failed to add the computer" + e.Message);

The example method has the following parameters:





  • Managed: WqlConnectionManager

  • VBScript: SWbemServices

  • A valid connection to the SMS Provider.


  • Managed: String

  • VBScript: String

  • The computer NETBIOS name.


  • Managed: String

  • VBScript: String

The SMBIOS GUID for the computer.


  • Managed: String

  • VBScript: String

The MAC address for the computer in the following format: 00:00:00:00:00:00.
