If you have WMI/DCOM enabled on the Windows machines, you can launch arbitrary programs via WMI, if your account has the appropriate permissions. See the links in DBD::WMI resp. Win32::WQL.

    I wasn't clear -- I need to calls Window systems from non-Windows systems. (There are of course RPC systems between Windows computers.)

      If you're really desperate, I think the Samba project also includes a DCOM client, and I believe that DCOM and Sun RPC are somewhat related. But to use that as your transport you must be really desperate, as a simple self-made server is easily created depending on how secure you want it to be.
