I am a HelpDesk Manager now. So I haven't been doing a lot of coding. Here is a dos batch script I put together to copy a configuration onto every computer inside of 254*4 ip addresses (ip addresses changed for obscure security):

for %%x in (117 118 119 121) do for /l %%y in (1,1,253) do for /D %%z in ("\\191.210.%%x.%%y\c$\documents and settings\*") do copy medpros.jgp "%%z\Application Data\Jolly Giant Software\QWS3270 Secure\medpros.jgp"
