I am inquiring if there is any fix for Windows Server 2012.

I had tried the setspn -s and used setspn -L DOMAIN\CEWS_Service_User_Name and the URI is listed utilizing the -L and username parameter.

Verified the CEP machine IIS AppPool user name is set with CEWS_Service_User_Name

Applied and verified Delegation Service Type (HOST and rpcss of ca.pre.domain.suf machine).

I am curious if anyone else have come across the same issue as below from the following site:http://technet.microsoft.com/en-us/library/tlg-key-based-renewal.aspx
