Yes qlikview with IIS is a PITA,
We have just recently installed QV9 with IIS6 in Windows 2003 i hope the following helps.
Install Qvs with IIS Support enabled
Open your (Enterprise)Management Console and make all nesscesary changes in the System->Web Servers ->Your Server to customize the server 4 your needs. --- Press Aply
Goto System->WebServers and change the url of your webserver into this "http://YOUTRSERVERNAME/QvAjaxZfc/AccessPointSettings.aspx" --- Press Apply
(Yes now you cant change your webserversettings from the management console anymore "NICE ONE QV" so you either have to edit the config xml directly or you have to enable the old server temporarily for changes )
And don't uninstall the QvWebserver the new aspx still needs its data.
- Open your IIS Managment Console.
-- In Yourcomputer-> WebSites ->DefaultWebsite you should now see Virtual Directories like Qlikview and QvAjazfc.
-- Open the ApplicationPools
--- There you have to create a new AppPool (call it whaterver you want Qvpool for example)
---- Open the Properties of the new Pool and Select the Identity Tab and change the identity to a user whos in the QlikviewAdministrator Group (preferable the one you have selected while QV installed)enter the correct password and press OK
-- In the Default Website Select the VirtualDirectory called QvAJAXfc and change its properties.There you change its Application Pool to the newly created one.---Apply :)
Edit all Qlikview Related VirtualDirectories in their Directory Security tab edit the Authentication and Access Controll where you enable anonymous access.(In the QvAJAXfc you can even untick the Windows integrated auth.. if problems arise)
Restart IIS and stop the QvWebserver Service.
Surf to http://yourserver/Qlikview/
Open a beer.
I hope this works for you and i havent forgotten something important.
BTW Im not sorry for my bad grammar and english
