Task Server - Cleanup Task Data/Update Summary Data

Hi,

We have NS 7.0 MR4. There is no job history for Cleanup Task Data or Update Summary Data jobs. If either of the jobs are run manually the last job previously listed is deleted. So what we are left with is the scheduled job and the one that last ran. Previously we had 2 months of histories for each of these respective jobs. I have restarted Altiris Service and IIS Admin Services on the Altiris Notification Server. With regards to this problem I am not sure why we aren't seeing more than one records of for each of these jobs that either ran correctly or failed. Ideas? Howto's?

Thanks.
