Check your Scheduled Task(s) to make sure you do not have the setting 'Do not store password...' selected. That can create havoc with Scheduled Tasks that try to access networked resources.
Otherwise, nothing springs to mind, except that you have flaky networking, and/or a Windows Task Scheduler that is corrupting credential information.
Bear in mind tens of thousands of people are using it to connect to networked resources fine (it's only people with problems that post...).
Note that it's not SBF that logs on to your system on a Schedule - the Windows Scheduled Task does.
