In SharePoint 2010, after installation, you will see a warning for unattended service account application Id.

“The Unattended Service Account Application ID is not specified or has an invalid value.”

In order to fix this, you need to create a new secure store target application. Go to Central Administration –>Application Management –>Manager Service Applications –> Secure Store Service –> Generate New Key (in the ribbon) –> Provide the pass phrase (important that you remember this) –> Click on New and provide details (Ensure to select target application type as Group). –> Add/Edit fields for credentials (For now accept the default) –> Provide the Target application administrators and members.

Once target application id is created, go to Go to Central Administration –>Application Management –>Manager Service Applications –> Global Settings –> Provide Application ID created in step 1 here.

Thats it..

Recently, while trying to configure Forms Services on SP2010 server, I got the following warning message.

“InfoPath Forms Services forms cannot be filled out in a Web browser because no State Service connection is configured.”

The message implies that you need to configure Session state service or Form View Service. Session state service uses SQL Server (default option), and FormView service uses asp.net ViewState. Since the default option is to use SQL Server, you need to provide connection string so that state service can use that as state store.
