As the title suggests this is the exception from my stacktrace.
I am trying to obtain a connection to my SQL Server 2008 R2 database hosted on a windows 2003 server.
Refreshing database in SQL Server Object Explorer helped me with that issue.
Try this, it may help you to create your database
Open command prompt, then type services.msc Now Services window will be opened
And, Open SQL Server Browser,Enable this and start it
The Resolving “A network-related or instance-specific error occurred while establishing a connection to SQL Server…” article explains how to address this issue. I hope, it will be helpful to you.
