In many places, SCCM uses a 16-character text string (actually a hexadecimal number) to represent one of the schedule token classes (SMS_ST_NonRecurring, SMS_ST_RecurInterval, SMS_ST_RecurMonthlyByDate, SMS_ST_RecurMonthlyByWeekday, and SMS_ST_RecurWeekly). Microsoft provides a WMI interface to translate between the text string and one of the SMS_ST_ WMI objects. Unfortunately, this interface is only accessible from the SCCM site server and it is not available to clients (who would not likely have the WMI access permission to the SMS_ScheduleMethods class). This post attempts to explain the string and provide methods to allow for its encryption and decryption.
