We have used IE55 IEAK (Corparate User Edition) to develop a customised version of IE. After reading the documentation I believe I can produce new INS files with 'Profile Manager' (part of IEAK).
The orginal installation enables 'use automatic configuration script' and sets the address to http://localhost/ie55/config/autoconfig.ins
. The server hosting the browser to be configured also has IIS V2 installed and running (Default with NT4).
According to documentation I should be able to produce a new INS file copy it to the config directory over writing autoconfig.ins and the new changes should be seen after a few minuites.
However this seems to have no affect.
