使用SQL Server 2008 Management Studio无法连接到远程SQL Server

Question

I'm trying to connect to a remote database with SQL Server 2008 Management Studio. I got the following error:

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, Erreur : 53)

I think that I have wrong with my config:

Can someone help me please ?

Answer 1

Steps to find out what the reason is:

1. Does the SQL server allow remote connections? Main settings SQL Server
2. Is TCP/IP enabled for client connections and listen on correct IP address / NIC?
3. Does the firewall on the server allow incoming traffic for the SQL Server port (default 1433)

It is normally one of the 3 points above.
