Generally this error occurs if you cannot connect to the SQL server - as the message says (no sh*t). However, what's not obvious is why...
First suggestion is to make sure that you specifiy the instance name as well as the ...(truncated)...

One morning when restoring my pc from hibernate - I got this error:
