You can change maintenance window properties for a collection, in Microsoft System Center Configuration Manager 2007, by using the SMS_CollectionSettings Server WMI Class and SMS_ServiceWindow Server WMI Class classes and properties.

To change the properties of a maintenance window

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Get the existing collection settings instance by using the existing collection ID provided.
Get the existing service window object by using the existing service window ID provided.
Change an existing property value (in this case the maintenance window description).
Save the collection settings instance and properties.

Note

The steps in the example method include additional steps, primarily to handle the overhead of dealing with the service window objects, which are stored as embedded objects in the collection settings instance.

Example

The following example method changes the properties of a specific maintenance window instance.

Important

This assumes that the collection instance can modified. This might not be the case at child sites, where the collections are owned by the parent site(s).

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

Sub ChangeMaintenanceWindowProperties(connection,                                 _
                                      targetCollectionID,                         _
                                      targetServiceWindowID,                            _
                                      newMaintenanceWindowDescription,            _
                                      newMaintenanceWindowServiceWindowSchedules, _
                                      newMaintenanceWindowIsEnabled)
                                       
    ' Get the specific collection settings instance.
    Set collectionSettingsInstance = connection.Get("SMS_CollectionSettings.CollectionID='" & targetCollectionID &"'" )
              
    ' Populate the local array list with the existing service window objects (from the target collection).
    tempMaintenanceWindowArray = collectionSettingsInstance.ServiceWindows 

    ' Enumerate through the array list to access each maintenance window object.
    For Each maintenanceWindow in tempMaintenanceWindowArray
   
         ' If the service window ID matches the one passed in to the function, change the specific values.
         If maintenanceWindow.ServiceWindowID = targetServiceWindowID Then        
                   
            ' Populate retrieved SMS_ServiceWindow object with the new maintenance window values.    
            maintenanceWindow.Description = newMaintenanceWindowDescription
            maintenanceWindow.ServiceWindowSchedules = newMaintenanceWindowServiceWindowSchedules
            maintenanceWindow.IsEnabled = newMaintenanceWindowIsEnabled          
        
         End If
        
    Next
    
    ' Replace the existing service window objects from the target collection with the temporary array that includes the modified service window.
    collectionSettingsInstance.ServiceWindows = tempMaintenanceWindowArray
    
    ' Save the new values in the collection settings instance associated with the collection ID.
    collectionSettingsInstance.Put_
    
    ' Output success message.
    wscript.echo "Maintenance Window " & targetServiceWindowID & " modified."

End Sub

public void ChangeMaintenanceWindowProperties(WqlConnectionManager connection,
                                              string targetCollectionID,
                                              string serviceWindowID,
                                              string newMaintenanceWindowDescription)
{
    try
    {
        // Create a new array list to hold the service window objects.
        List<IResultObject> tempMaintenanceWindowArray = new List<IResultObject>();

        // Establish connection to collection settings instance associated with the Collection ID.
        IResultObject collectionSettings = connection.GetInstance(@"SMS_CollectionSettings.CollectionID='" + targetCollectionID + "'");

        // Populate the array list with the existing service window objects (from the target collection).
        tempMaintenanceWindowArray = collectionSettings.GetArrayItems("ServiceWindows");

        // Enumerate through the array list to access each maintenance window object.
        foreach (IResultObject maintenanceWindow in tempMaintenanceWindowArray)
        {
            // If the service window ID matches the one passed in to the function, change the specific values.
            if (maintenanceWindow["ServiceWindowID"].StringValue == serviceWindowID)
            {
                maintenanceWindow["Description"].StringValue = newMaintenanceWindowDescription;
                break;
            }
        }

        // Replace the existing service window objects from the target collection with the temporary array that includes the new service window.
        collectionSettings.SetArrayItems("ServiceWindows", tempMaintenanceWindowArray);

        // Save the new values in the collection settings instance associated with the Collection ID.
        collectionSettings.Put();
    }
    catch (SmsException ex)
    {
        Console.WriteLine("Failed. Error: " + ex.InnerException.Message);
        throw;
    }
}

The example method has the following parameters:

Parameter	Type	Description
connection swebemServices	Managed: WqlConnectionManager VBScript: SWbemServices	A valid connection to the SMS Provider.
targetCollectionID	Managed: String VBScript: String	The ID of the collection.
serviceWindowID	Managed: String VBScript: String	The ID of the maintenance window for which to change properties.
newMaintenanceWindowDescription	Managed: String VBScript: String	The description of the new maintenance window.
