This issue has been fixed in DS 6.8 SP2.

There appears to be several functions that are affected because of this bug. MoveComputerByGroupName and CreateJobScheduleByName are two known functions to be affected by this situation.

The work around is to use the CreateJobSchedule function as it is not affected by this particular problem. The following snippet of code can be helpful to show the implementation that should be used:

   int scheduleID = scheduleManagment.CreateJobSchedule(computerID, jobID, false, "ASDK",
   @"<ScheduleAttributes xmlns='http://tempuri.org/ScheduleAttributes.xsd'>
    <Schedule_Attribute_Table>
     <start_time>9/12/2007 5:24:21 PM</start_time>
     <defer_time>5</defer_time>
     <recurrence_value>1</recurrence_value>
     <recurrence_type>Hours</recurrence_type>
     <batch_size>0</batch_size>
     <batch_interval>0</batch_interval>
     </Schedule_Attribute_Table>
    </ScheduleAttributes>");
   Console.WriteLine ("CreateJobSchedule complete" );
