best network monitoring program -free

I need a program that can hold a list of companies that I can easily just ping them, let me know when they are down, let me telnet into the router and even dial into a modem? I know I can just do it in cmd but I want to be able to do it faster, even automate it.

There are plenty of basic network monitoring tools but I don't know if any of those listed will do everything you require.

You may be best to ask on a dedicated network forum.
