Usually if you install OBIEE 10.1.3.4 version there will be two option for Web Server . You can choose either OC4J or IIS .Selecting OC4J will not install IIS at all . But since there are some nagging OC4J service window keep block at-least one window all time(bit reluctant about creating OC4J service as windows services) hence thought it is nice to have IIS configured so that the dependency from OC4J can be avoided and there will be dual usage possible from any one of the Web Server .
In my blank window machine I have IIS pre-installed but not configured for OBIEE. Hence I have followed below step by step process to configure blank IIS . Pls follow the steps directed from top left images across right and then next row etc etc….
