回复：纵横B2B电子商务系统XYECS!B2B 2.2安装图解.
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)
提示这样的错误，安装不了
唉，网上说的
检查后发现是webconfig的配置问题，将server＝local，改成本地计算机名，问题解决。
如：
<connectionStrings>
<!--链接SQL Server数据库的链接字符串-->
<add name="Mispersonalconn" connectionString="data
Source=192.168.133.31;database=DB_Mispersonal;uid=sa;pwd=;"
providerName="System.Data.SqlClient"></add>
</connectionStrings>
还是改不了
