You may have noticed (maybe not) that SSP Timer jobs such as user profile imports and audience builds, are not included in Central Administration --> Operations --> Timer job Status/Definitions. You will notice 1 or more Shared Services Timer Jobs, 1 for each SSP in the farm. While you can disable the service as a whole, you cannot reset or clear timer jobs for an SSP individually.
To accomplish this, run from the 12 Hive/bin directory:
stsadm -o enumsptimerjobs -title
You can then delete any listed jobs with:
stsadm -o deletesptimerjob -title -jobid
Note: If your title has spaces, you must surround with “SSP Title” using stsadm.exe. You must also recreate any jobs that need to run in the future, as their definition will be gone.
