If you want to use Perl script and windows scheduler to stop, start, restart a service at specific time, here is a script (based on Win32::OLE) you can use:

use Win32::Service;
use Win32::OLE;
my $hostName= $ARGV[0];
my $serviceName=$ARGV[1];
my $command =$ARGV[2];
my $command2 =$ARGV[3];

if ($#ARGV <2)
{
print "Usage: $0 hostName serviceName command[stop|start|restart|start_if_not_running] command2 \n";
exit (0);
}

%status =(1 => 'STOPPED',
2 => 'START_PENDING',
3 => 'STOP_PENDING',
4 => 'RUNNING',
5 => 'CONTINUE_PENDING',
6 => 'PAUSE_PENDING',
7 => 'PAUSED',
8 => 'ERROR');

$ADsPath = "WinNT://$hostName/$serviceName,service";
$s = Win32::OLE->GetObject($ADsPath) or die "Unable to retrieve the object for $ADsPath\n";
print $hostName ." | ". $serviceName .": ". $status{$s->{status}} . "\n";

my $cur_status = $status{$s->{status}};
if ( $command eq "stop")
{
$s->Stop();
}
if ( $command eq "start")
{
$s->Start();
}

if ( $command eq "restart")
{
$s->Stop();
sleep(60);
$s->Start();
}

if ( $command eq "start_if_not_running" && $cur_status ne 'RUNNING' )
{
$s->Start();
}

sleep(30);

$cur_status = $status{$s->{status}};
print $hostName ." | ". $serviceName .": ". $cur_status . "\n";

$hostName=lc($hostName);

if ($hostName eq "localhost")
{
if (($command eq 'start' || $command eq 'restart' || $command eq 'start_if_not_running') && $cur_status ne 'RUNNING')
{
my $command="net start $serviceName";
system($command);
}
if ($command2 ne "" && $command ne "stop")
{
sleep(30);
system($command2);
}
}
