Switch off your DSL router.

Install a firewall app. I used Comodo Firewall in the past and it's excellent. Once the app tries to connect to the net, Comodo will pop up with a warning and you can select to disable it sending data to wherever.

Unplug your ethernet cable...

Shutdown your power at the mains

Add a dummy proxy ip address in the program settings, and it won't be able to connect

Which Operating SYSTEM is the program running on?
What is the name of the program you want to prevent from having access to the internet?
Do you perhaps have a domain name/IP Address where it connects to ?
Why do you want to prevent it from accessing the internet?

What program? What port? Try tcpview from here : https://technet.microsoft.com/en-us/sysinternals/bb842062.aspx . Will show you what processes are connecting to where

Except it's often not the program itself that's connecting. Vagueness doesn't help when troubleshooting or trying to solve problems.

There are many ways to skin a cat, except it may not be a cat

Well, I'm on windows 10.
Control Panel > System and security > Windows Firewall > Allow app/feature through firewall > Click the change settings thing > search for your app in the list and untick. If it isn't in the list, add it and untick.
(you can skip the control panel and System and security by opening run/start menu and typing in firewall.cpl and hitting enter, this applies from XP to 10.)
