New Post: trying to simply change tasks to disabled.

no, the task is still enabled via the UI and Code. but the register is successful in the history of the task. This is what is most strange.
I do have administrative rights to this test environment. AD domain admin.
the task is updated according to the history, but does not register the change.
I have tried connecting to remote server new TaskService(servername, adminuserid,, PW) with and without the id and PW to no avail.
the task shows a status of Ready,
and the trigger is also still at Enabled.
No errors.
