当使用Linked Server连接sql server 2000, 出现OLE DB provider "SQLNCLI" for linked server "server130" returned message "Login timeout expired".
OLE DB provider "SQLNCLI" for linked server "server130" returned message "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.".
Msg 1326, Level 16, State 1, Line 0
Named Pipes Provider: Could not open a connection to SQL Server [1326].  这个错误提示。后来才发现安装有sql server数据库的电脑处于不同的网段。 这时就需要在装有sql server 2005的电脑上的C:\WINDOWS\system32\drivers\etc\hosts中添加要连接电脑的IP地址和电脑名,同时注意端口最好使用默认的1433.
