in reply to Executing Windows commands using backtick
Have you tried to execute the commands from the command line without perl?
I'd try that first, then I would have perl create a .bat file or use a template file to execute what you want to do and then run the batch file. I suggest the template method as the file may need to be encoded in the correct code page to execute correctly
Stackoverflow.com has several items that may help you on this as well.
