使用PowerShell的Windows 2008中的計劃任務

Question

我想在Windows 2008 R2中使用PowerShell計劃任務。我用

$username = "BUILTIN\Users" 
    $TaskName = 'kakaka' 
    $t=1 
    $TaskRun = "$PSHome\powershell.exe Start-Process -FilePath 'C:\v.exe' -ArgumentList '/a' -Verb runas -WindowStyle Normal" 
    $start = (Get-Date).AddMinutes($t).ToString("HH:mm") 
    schtasks /create /ru $username /tn $Taskname /tr $TaskRun /sc once /st $start /f 

上使用上述腳本我得到一個錯誤「SchTasks.exe會：錯誤：任務XML包含格式不正確或超出範圍的值。」同樣的腳本運行良好在Windows 7

似乎有密碼的問題，這是後下解決了：

SYMPTOMS 

When you try to change the run as user for a scheduled task in Server 2008, The task is currently configured to runas SYSTEM. Using the following command line he receives the error. 

c:\>SCHTASKS /CHANGE /TN TestTask /RU TestUser 

SCHTASKS prompts the user for a password for the runas user account. After entering the password it displays the following error. 


"ERROR: The task XML contains a value which is incorrectly formatted or out of range. (52,4):Task:" 


The task's runas credentials have not changed. 


RESOLUTION 

To avoid this error you must add the /RP option with an "*". The new command line will look like this: 

c:\>SCHTASKS /CHANGE /TN TestTask /RU TestUser /RP * 

SCHTASKS prompts the user for a password for the runas user account. After entering the password the task is updated without error.
