I've just installed SQL Server 2008 R2 Express on a Windows 7 laptop. When I start up the Management Studio and try to connect with Windows authentication, it gives the error -

TITLE: Connect to Server
------------------------------

Cannot connect to SQLEXPRESS.

------------------------------
ADDITIONAL INFORMATION:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)

The SQL Server (SQL EXPRESS) and SQL Server Browser services are running and the Agent service is stopped.

Once again, I'd appreciate any help.
