ETL schedule not not executing

Depending on your version, the problem might be that the password for the user who published that job had changes, but the changes was not updated in Cognos. You need to manually reset credentials. Here are the instructions:

For first time.....
Tools> MyPreferences>Personal>create credentile>Renew the credentile
OR
If you already been there then the options should be like this
Tools> MyPreferences>Personal>Renew the credentile

Hope this helps

You might also want to check the official technote from IBM on this issue: http://www-01.ibm.com/support/docview.wss?uid=swg21459514

Also, as previously mentioned this was resolved in Cognos 10, so if you're on a newer version of Insight this may not be your problem, but I would start here.
