We had a problem with our OS Provisioning halting at various places along the process (we are also on 9.50 SP1). It turned out there is a problem with using SD inside of the OS Provisioning process. I am not certain, but if your Adobe is an SD task I suggest you convert it to an OSP task by copying it to the local device (as a task) and then running it there (as an executable task). This problem has been confirmed and is being rectified by LANDesk for some future update. In the mean time we have converted ALL of our SD tasks in provisioning to execuatable tasks.
Secondly, we have discovered a number of issues with SP1 itself. The one that is causing a problem for the SD team is that the LANDesk inventory does not display all of the items in the "Software.Add or Remove Programs. Program" table when it scans Windows 7 machines (XP works correctly). It imay be necessary to get your TAM or some LANDesk representative to authorize you for LD95-CP_BASE-2013-1017 if you indeed require that fix.
