Good day!

I am newly in SQL Server 2005 and now I encountered error when i try to login. This is some of the information:

Microsoft SQL Server 2005 Express Edition

Server Type: Database Engine
Servername:Servername\MSFW
Authentication:SQL Server Authentication
Login: sa
Password:xxxx

and when i press the connect button the error appear:

Error:
Cannot connect to Servername\MSFW

Additional Informations:
An error has occured while establishing a connection to the server. When connecting to SQL Server 2005, this failure may becaused by the fact that under the default settings SQL Server does not allow remote connections.(Provider:SQL Network Interfaces error:26-Error Locating Server/Instance Specified) (Microsoft SQL Server).

I have no idea where i can solve this problem..

Any help is highly appreciated..

Thank you in advance.
