I never do Perl programming on Windows, but I think it's a network problem. It seems the script is having problem either in Win32::NodeName() or Win32::Service::GetServices(). I guess it's the latter. My wild guess would be that the latter is trying to query $Machine about what services it is running and this usually requires $Machine to run a service that sits on a specific port and can answer that query.

As I said. I am not a Windows programmer and it's all just wild guess that I get from the error message.

Hope that helps.
