You set it under the Configuration menu.

Can you give an example on how you could do this with other broker/trading software combination?

In order to automate a strategy with NT and IB, you have to establish a connection between TWS and NT. TWS is connected to IB servers and not NT. With most other data providers NT is connected directly to the data providers and can detect failures directly. When I used TWS with NT there was no way for TWS to alert NT that connection was lost to IB servers.

I do not have experience in this... I have a few questions:

1. How does NT detect disconnection with other brokers? (which brokers?)

2. What is NT going to do if there is a disconnection?

3. How is NT going to alert you if there is a disconnection?

Where did I say that you could or should? As far as I know most other providers have a direct connection between NT and the providers servers and you don't have to rely upon another application.

1) Not sure, I would suggest you check with NT's docs or support staff to be certain.

2) Try to establish a new connection, something it doesn't know to do if TWS stops working.

3) There are probably several ways, I would suggest you check with NT's docs or support staff to be certain.

I still do not understand your point...

so what would happen if there is a disconnection?

what would do what?

1. the broker software would take some action? like what?

2. the broker server would take some action?
e.g. liquidate your positions?
do you program the broker's side for action?

3. NT would take some action? What actions?

TWS automatically and continuously retries connection when broken.
This is just a basic function, I am sure any broker's software would do the same.

Really? I had internet issues recently with a bad DSL connection and got frequent "Connection Lost" voice prompts from NT each time this happened and TWS lost connection.

Are you actually using IB, or is your comment based on what you "heard" or from something long ago? Not trying to sound rude and apologize if it sounds like it, but I think this is important to know if your comments are based on real experience or heresay or based on using something very long ago.

I am still unclear how this an issue with automated systems? Are you saying that when running an automated system in NT that it will send orders to IB even though there is no active data feed when your internet connection is down because you cannot detect it automatically in the strategy? What would the NT strategy base it's orders on then? Sounds like an NT issue to me and not an IB issue.
