add bunch of putty sessions. This requires cygwin base install which includes the sed command. Be sure to add \cygwin\bin to the path:
create a "template" putty session with all the settings you want. go into the registry and export the session: HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions\session_name
put a list of machine names in test.txt
then in dos:
for /f %a in (test.txt) do type m.reg | sed -e 's/Template_NAME/%a/g'>> all.reg
These sessions can then be used in putty session manager or any of the other putty related tools.
