Automatically dialing in win98

Situation:

Pentium III 800 MHz machine being used as a server installed with WIN98. The machine is being used in a cable system as a server. If for any reason the machine is shut down/restarted and there is no operator to reconnect it to internet. Is there any way that this server dials it automatically after restarting.

Moreover how the same thing can go in the same system but with win Nt operating system in it.
