I tried setting up [Cognos](http://www.cognos.com/?ref=kudithipudi.org) (Business Intelligence tool mainly used for reporting) on a test machine for Lakshmi to play around with. After going through the install, I can say with confidence that Cognos has some of the worst documentation :). Here are some quick tips that you won’t find in the official documentation for someone trying to configure Cognos BI 8.x on a Win2k3 server running MS SQL 2005 and IIS 6.0.

1. After installing Cognos, run the “**Cognos Configuration**” tool and change the “**Gateway URI**” setting to ***“http://servername:portnumber/cognos8/cgi-bin/cognosisapi.dll***” in the **environment** section.
2. Edit the **default.htm** and **index.htm** file in the “**< cognos install directory >\\cognos\\c8\\webcontent”** directory and replace **cognos.cgi** with **cognosisapi.dll**
3. Open ISS manager and go to Web Service Extension. Add a new web service extension called **isapi** and add **cognosisapi.dll** as a required file. Make sure to set the extension status to Allowed.

This should enable you to launch cognos and log into the web interface.
