Powershell：执行Recieve-Job时收到访问被拒绝错误

Question

我有一个小的PowerShell脚本，我想通过Nagios监控执行验证，如果某个目录存在是或否。在Powershell ISE中调试和/或运行脚本时，每件事都可以，并产生所需的结果。通过Nagios安排脚本时，我收到了拒绝访问权限＃34;错误。

脚本中产生错误的行：

$testJob = Start-Job -scriptblock {test-path $($args[0])} -credential $ipmamCredentials -argumentlist $ipmamdir
$finished = Wait-Job $testJob
$result = Receive-Job $testJob

Nagios产生的错误：

Receive-Job : [localhost] There is an error launching the background process. Error reported: Access is denied.
At C:\Program Files\NSClient++\scripts\check_ipmam_drives.ps1:19 char:26
