When you use the IE Task Scheduler, to schedule a task on your BDC, the task does not run.
On the BDC, open %SystemRoot%\Schedlog.txt and look for:
The attempt to log on to the account associated with the task failed, therefore, the task did not run. The specific error is:
0x80070569: Logon failure: the user has not been granted the requested logon type at this computer.
Verify that the task's Run-as name and password are valid and try again.
If you find it, use User Manager for Domains to grant the local Administrators group the Advanced Right to Log on as a batch job.
