Scheduling Reports Intermittent

[dfreed]

Hi all,
we are trying to set up a schedule to run on some reports in our production environment, but it seems that no matter what interval is selected the scheduler skips every other instance (or every two instances).

For example, I set up a test report to run for a full day in half hour increments.  I created it around 11am to start at 11:30am.  I didn't get my first email until 12pm, and then would only receive reports in 1 hour or 1.5 hour intervals. 

I also tried setting up a job that runs two reports.  The schedule runs the same way.  However when I run the job manually, only one report successfully runs.  The report that ran successfully alternates each time the job is run, and the other one always fails.

I'm at the end of my rope here, and am hoping someone has a good answer for me.  Is there a setting in Server Administration I'm missing?
