Cognos Analytics 11.0.12
Microsoft Windows 2012 Server
TM1 10.2.2

The IBM Cognos Windows service look like it is started in Windows, but when you try to login you get a message that the page can not be shown. When starting Cognos from Cognos configuration you get message CFG-ERR-0106 … did not receive response from the IBM Cognos service in the time allotted. You can not surf to http://servername:9300/p2pd/servlet
The firewall is not blocking the connection.

Possible solution:
A other software was installed on the Cognos BI server, that uses JAVA and have set JAVA_HOME, JDK_HOME and JRE_HOME as windows variables. You can see this by enter SET at a CMD prompt on the server. This have given that Cognos have used the wrong java version.

Adjust JAVA_HOME to point to the Cognos java folder.
