I have a simple perl script that opens excel and reads data from one of the tabs. This script works from the cmd line, but will not work when launched via the task scheduler in windows server 2k8. The task will complete successfully with no errors, however the data is not read. My assumption was that the task scheduler is unable to open excel and read the data, but the task does work when I run it from a workstation (Vista). I configured task security to run with highest privileges. I created the task using a domain admin account and the Excel sheet security allows full control for this account. I am also not running this from a network share. I cannot figure out why this works with the same credentials scheduled from a task on a Vista machine, but not via the task scheduler on w2k8 Server. I have no errors to try and troubleshoot the problem. Thanks!
