In windows2012, IIS is not able to configure in Microsoft Failover Cluster

Question

Hello All
I configured IIS under Microsoft Failover Cluster with the help of below link. The setup is working successful. I configured this on Windows2008.
http://support.microsoft.com/kb/970759/en-us
I verified below as test cases.
1.) I kill PID of W3SVC , the failover executed.
2.) I stopped the Default Web Site, the failover executed.
3.) I stopped the Default Application Pool, the failover executed.
4.) I stopped the other Application Pools, the failover executed(after changing the script under above mentioned link).
PLEASE NOTE: I used the following links to configure the setup on Windows2008 and Windows2012
http://zahidhaseeb.wordpress.com/2014/02/12/how-to-configure-iis-web-site-and-application-pool-in-microsoft-failover-cluster/
But, when I create the same environment under Windows2012, see what happen below.
I verified below as test cases.
1.) I kill PID of W3SVC , the failover executed.
2.) I stopped the Default Web Site, the failover executed.
3.) I stopped the Default Application Pool, the failover executed.
4.) I stopped the other Application Pools, the failover is not executed(after changing the script under above mentioned link).
Any comment will be appreciated. Thanks. Zahid Haseeb.

Hi,
As the KB mentioned, Microsoft recommends administrators carefully evaluate the use of Network Load Balancing (NLB) as the primary and preferred method for improving the scalability and availability of Web applications with multiple servers running IIS 7.5
or IIS 7.0, as opposed to using failover clustering.
It is important to consider that clustering IIS by means of clustering the IIS services does not always guarantee a high availability solution for Web applications.
While the IIS services (specifically the WWW service) might be up and running, a specific application pool’s hosting process could have terminated, or the application might be throwing internal server HTTP errors. Clustering the Web applications and
monitoring their health by using a custom script is the correct and recommended way to achieve a high availability IIS cluster using failover clustering. Below is a sample script that monitors the state of an application pool to determine if it is started
or not.
That’s more about the IIS issue, maybe you can ask more detail question in IIS forum.
