Taks Schedule do not work well.

Hi,

I was using the task scheduler to do a lot of jobs in a automatic way,
but not anymore.

For the past two months it begginned to fail. It just stopped to
function. I need to enter in the job properties, write down the
password again, ..., and, ..., it resembles to work well. It do not
really work well, as it used to do.

In fact, It work well just for some time, and then, after this, it just
stops to function.

Could anybody give some help, please?

Thanks, Jorge.
