出错提示：An error has ocurred while establishing a connection to the server.When connecting to sql server 2005,this failure may be caused by the fact tha under the default settings sql server does not allow remote connections.(Provider:Named pipes provider,error:40-could not open a connction to sql server).为什么会出现这个错误啊？
sql server的server端也是装在笔记本里的，这样有没有问题呢？
