muralidharan has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks!!! The Win32::Scheduler module works fine in local machine to schedule a perl file. But when trying to connect to a remote go grid machine, it doesn't, and creates the job in local machine itself. There is a method - SetTargetComputer() where the host machine name is given. But i'm unaware where to give the Go grid machine's password. Here is my code

$scheduler = Win32::TaskScheduler->New();
$scheduler->SetTargetComputer("173.1.105.147");
$tsk="my_task";
%trig=(
       'BeginYear' => 2010,
       'BeginMonth' => 02,
       'BeginDay' => 9,
       'StartHour' => 13,
       'StartMinute' => 06,
       'TriggerType' => $scheduler->TASK_TIME_TRIGGER_DAILY,
       'Type'=>{
               'DaysInterval' => 1,
       },
);

$scheduler->Activate($tsk);
foreach $k (keys %trig) {print "$k=" . $trig{$k} . "\n";}
$scheduler->NewWorkItem($tsk,\%trig);
$scheduler->SetApplicationName("cmd.exe");
$scheduler->SetAccountInformation('usrname','pwd'); #username and pwd 
+for the particular task
$scheduler->Save();
$scheduler->End();

Re: Can Win32::Scheduler Module used to schedule a remote host?

    The first thing is the remote computer name should be a UNC (eg.\\remoteHost) not an IP.

    Next, you should be checking the return values of the method calls. They would probably go a long way to identifying what is going wrong.

      Thank you for your reply!!!!!!!! Actually the remote go grid server doesn't have a UNC. It is usually connected from here through the remote desktop connection (mstsc) with its IP. And moreover, even if we give the UNC, where should i give the user name and password?? The username and password i'm giving in the code is for scheduled task.

      Thank You.

        Under the normal MS scheme of things, connections to remote machines are done under the credentials of the userid that runs the code. Ie. Whatever id you run your script under will need to be authorised to connect to the remote machine on which you are hoping to schedule the task.

        Whether Win32::Scheduler operates that way I don't know, but it seems likely.
