Cognos ISAPI problem, no Gateway URI configuration option

[zakatak]

I am in the process of building a new Cognos environment.  The Cognos portion of the environment has 3 servers; a Content Manager server, an Application server, and a Gateway server.  Each machine is Windows Server 2012.  Everything appears to be connecting to each other.  If I point a browser to http://cogweb01/ibmcognos/isapi then I am presented with the welcome page.  If I point a browser to http://cogweb01/ibmcognos I get 404.3 message stating the URL cannot be found.  When I look at the address of 404.3 I see that it is trying to use cognos.cgi whereas the one that works uses cognosisapi.dll.

In the inst_cr_winux.pdf that is included in the install files I am directed to:

11. Start IBM Cognos Configuration.
12. In the Explorer panel, click Local Configuration > Environment.
13. In the Gateway URI box, change the cognos.cgi part of the URI to
cognosisapi.dll.

However I do not have a Gateway URI box nor any values with cognos.cgi to change to cognosisapi.dll.

Any ideas what I've missed?

This link will help you.

Check the heading 'Making the ISAPI Gateway the default'
You need to modify default.htm and index.htm files as specified.

Thank you, that helps quite a bit.

I'm still having an issue, but I think it might be IIS-related this time.  http://servername/ibmcognos directs me to the isapi module and everything is peachy, but http://servername.domainname.tld/ibmcognos directs me to the cgi module...

So that's fun.  Thanks again.

So that issue that was an issue is not really an issue once I clear the browser cache on the local machine.

So thanks again.
