An error has occurred while establishing a connection to the server.  When connecting to sql Server 2005, this failure may be caused by the fact that under the default settings sql Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to sql Server)

用ASP写的程序   连接数据库时抛的异常   有人遇到过没 ？  
    给个解决方案   谢了 ..
