504 Gateway Timeout from an IIS Server

Question

I am using a web Server based on IIS,I am using an Infor Application which is trying to fetch data from the Web Server. However when there is a lot of data and the query runs more than 60 seconds, i get a Gateway Timeout Error(504).

Where do i set the configuration to increase till say 2 minutes or 5 minutes? Any Help would be appreciated.

If as the other answer suggests, you are using ARR, there is another undocumented setting which often causes 502's
