Problem with Repository scheduler DS 4.1

Hi.

I'm trying to program the job scheduler of various interfaces.

I notes this things:

1) My repository does not have job servers associate (adapters)

2) In the tab "Batch job configuration" I can execute the job and works fine.

3) In the "Repository Scheduler" there is not "Job Server".

4) with this configuration doesn't start.

5) And When I try to create the job with this configuration , I have this message:

Error:Enterprise authentication could not log you on. Please make sure your logon information is correct. (FWB 00008)

I have the Administrator privileges So I can see the configuration of the servers and security for data services.

What can I check?

Thanks a lot
