错误代码如下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) 应该是和数据库没有连接上，但是小弟我的程序在sql2000和sql2005上测试通过，折腾2天了，请各位高手帮帮忙了，小弟我感激涕零！！
