Answer 1

• You have a named instance of SQL Server named SQLEXPRESS (this is shown in parentheses within the SQL Server service name " SQL Server (SQLEXPRESS) " in the Windows Services MMC snap-in.
• You need to specify the instance-name in the Server name: field.
• You can only omit the instance-name for default instances .

You need to specify .\SQLEXPRESS or (local)\SQLEXPRESS to be able to connect.

Answer 2

Try connecting using .\SQLEXPRESS as the server name.

It seems you have created an instance with the name SQLEXPRESS . With SQL server you can create "instances". Each instance is like its own separate database engine and has its own list of databases, users and so forth. There can be one default instance which would be just the computer name or . . In your case you have a named instance "SQLEXPRESS" which you need to address using .\SQLEXPRESS or <computername>\SQLEXPRESS .
