To start up a process on a remote machine, you might try using WMI. Here's an old test Perl script I wrote ages ago to do that:

use Win32::OLE qw(in);
use Win32::OLE::Variant;
my $cmdline = "notepad";
my $machname = 'dev-autotest';
# This is the WMI moniker used to connect to CIM repository.
my $class = "WinMgmts:{impersonationLevel=impersonate}!//$machname";
# Get the WMI interface.
my $wmi = Win32::OLE->GetObject($class) or die "error: Get WMI $^E";
# Get a Win32_Process class object.
my $proc = $wmi->Get('Win32_Process') or die "error: Get Win32_Process
+ $^E";
# Create a BYREF variant so a COM object can modify its value
# and return it to us.
my $vPid = Variant(VT_I4 | VT_BYREF, 0);
# Create the new process
if ($proc->Create($cmdline, undef, undef, $vPid) == 0)
{
   print "process created ok, pid=$vPid\n";
}
else
{
   print "process create failed $^E\n";
}
