Very simple problem to solve unexpected easily in IIS Manager

Introduction

When installing a WCFservice, my browser told me kindly 'A binding instance has already been associated to listen URI.......'. That installation worked on so many other machines before, that it was strange.

How To Possibly Solve

When Googling on this problem, you will find tons of articles indicating to change a binding. In this case, it was astonishingly simply to fix this in IIS. Besides http, we use net.tcp for our services.

In IIS Manager, under 'Default Web Site', right-click 'Manage Web Site' and then select Advanced Settings. You will see a section called 'Behaviour'.

Make sure the Enabled Protocols show 'http,net.tcp'. If you would state 'net.tcp,http', you would get the errormessage complaining about your binding instance being already associated.

I started in the eightees with Basic and QuickBasic. When the ninetees started dBase was my thing. Close to the millenium years I swapped to C++ and since 2003 it is only programming in c#.

There is one thing about me.
Not that kind of OO guy and definately not an ORM-fan. I know a database to well to give the importance of data out in the hands of a tool.
