Error: The report server installation is not initialized in SharePoint 2010 farm

Interesting problem whilst configuring SQL Server Reporting Services (SSRS) integration on the web front end in a new SharePoint 2010 farm

I’m using SharePoint Server 2010 fundation with Service Pack 2 and the Augest 13 CU applied. SQL Server 2008 R2 is the DB latest version. Using the Reporting Services Configuration Manager I’d configured Reporting Services on the server to point to the Reporting Services DB on the back-end database server and created the relevant virtual directories on the server. For the time being the service account is being used for the Reporting Services integration.

Next I’ve gone to Central Admin –> General Application Settings and selected Reporting Services Integration and successfully completed the configuration as you can see from the picture below.

The next step is usually to return to the General Application Settings page and select Set server defaults under Reporting Services but as soon as I did this I received the following error…

 

Resolution :

The tip was to return to Reporting Services Configuration Manager and click on Encryption Keys in the left menu and then delete the encrypted content.

 

and when I returned to the General Application Settings page and ran Set server defaults it now worked as expected and allowed me to maintain the default settings for Reporting Services
