windows 2008 年使用 powershell 调度任务

Question

我想用 powershell 在 windows 2008 r2 中安排任务。我用了

   $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

在使用上面的脚本时我得到了一个错误 "schtasks.exe : ERROR: The task XML contains a value which is incorrectly formatted or out of range." 相同的脚本在 windows 7.

上工作正常

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.
