[讨论]IIS发布问题.

我是用的 sql2000+vs2005开发的程序 在发布的时候
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)
出现的这种错误 ,请高手指点.
