The error message informs you that you were not able to reach the SQL Server instance you specified. There can be a number of reasons for this error:
- SQL Server is not running.
- Server and / or instance name is incorrect.
- There is no SQL Server instance on the machine you are trying to connect to.
- There are firewalls blocking the way. (When trying to connect to SQL Server on another machine.)
- When connecting to a named instance, the SQL Server browser service is not running. (When trying to connect to SQL Server on another machine.)
You don't any include any information on why you expect connection to succeed, so I am left to a guessing game. What looks suspect in the error message is the instance name. Is that really correct? (I am not sure that space is event permitted in instance names.) The default name for an instance of SQL Server Express is SQLEXPRESS, so maybe that is what you should try.
Are you able to connect with SSMS (SQL Server Management Studio). Profiler is no different.
