Good Day ,
Innitally my prod server was running with SQL server 2008 and i tried to install some of the component from SQL server Configuration Center using SQL Server 2008 R2 . Those coomponent i installed was Client Tools Connectivity , Clients Tools SDK , Bwrd Compatability , Client Connectivity SDK from media SQL Server 2008 R2. Now once restarted the server i couldnt access to the existing management studio nor the database from the server itself. But i could connect and view the objects from SQL connection to this server.The error pop up was as following:
