Use the windows ftp command. Is has a -s option for providing ftp "scripts". Basically just add all the commands you need to accomplish your task to something.txt for example:
open 192.168.100.112
get file.txt
close
open fpt.website.com
cd docs
put file.txt
close
bye
then do:
ftp -s:something.txt
You could make ftp scripts, one for each upload. Then put all five commands in a batch file
