In System Center 2012 Configuration Manager, you set the distribution point response to incoming PXE requests by setting the IsActive embedded property.

IsActive has the following possible values.

Value Description

0

The distribution point does not respond to PXE requests.

1

The distribution service point responds to requests.

To set the distribution point response to PXE requests

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

  2. Make a connection to the distribution point instance with PXE enabled.

  3. Get the embedded properties.

  4. Update the IsActive embedded property.

  5. Commit the changes to the site control file.

Example

The following example method sets the response for a PXE request based on the supplied String value (allowResponse).

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

C#  Copy Code 
public void SetAllowResponse(WqlConnectionManager connection,
								string siteCode,
								string serverName,
								string allowResponse)
{
	try
	{
		//Connect to distribution point instance.			
		IResultObject siteRole = connection.GetInstance("SMS_SCI_SysResUse.FileType=2,ItemName=\"[\\\"Display=\\\\\\\\" + serverName + "\\\\\\\"]MSWNET:[\\\"SMS_SITE=" + siteCode + "\\\"]\\\\\\\\" + serverName + "\\\\,SMS Distribution Point\",ItemType=\"System Resource Usage\",SiteCode=" + "\"" + siteCode + "\"");

		// Create temporary copy of the embedded properties.
		Dictionary<string, IResultObject> embeddedProperties = siteRole.EmbeddedProperties;

		// Enumerate through the embedded properties and makes changes as needed.
		foreach (KeyValuePair<string, IResultObject> kvp in siteRole.EmbeddedProperties)
		{
			// Setting: IsActive
			if (kvp.Value.PropertyList["PropertyName"] == "IsActive")
			{
				// Get current property value.
				Console.WriteLine();
				Console.WriteLine("Property: {0}", kvp.Value.PropertyList["PropertyName"]);
				Console.WriteLine("Current value: {0}", kvp.Value.PropertyList["Value"]);

				// Change value.
				embeddedProperties["IsActive"]["Value"].StringValue = allowResponse;
				Console.WriteLine("Setting the {0} value to {1}.", kvp.Value.PropertyList["PropertyName"], allowResponse);
		}
	}

		// Store the settings that have changed.
		siteRole.EmbeddedProperties = embeddedProperties;

		// Save the settings. 
		siteRole.Put();
}
	catch (SmsException ex)
	{
		Console.WriteLine();
		Console.WriteLine("Failed. Error: " + ex.InnerException.Message);
}
}
