Powershell Script not running through Task Scheduler
I am getting the desired output from the below script manually through PowerShell ISE. But the same script is not running through Task Scheduler. It's showing as completed (in Task Scheduler History)...
F:\ is a local disk? Which account are you running the Task? You could add a Start-Transcript c:\temp\log.txt as the first line and a Stop-Transcript as the last line to see what's going on if it's being run as a Task. (Create c:\temp first, or choose another location)
Yes. F:\ is a local drive. As per my latest observation the task scheduler can't read the encrypted password file (F:\Reports\ImpCred\encrypted_passwd.txt).
