具有IP，端口和基础提供程序的连接字符串在打开时失败

问题描述

嗨伙计们

i创建了一个需要连接到sql server 2008数据库的程序，这个程序将运行在5台计算机上，通过无线调制解调器[或路由器]
，数据库在该计算机上。所以我应该如何在其他计算机上设置连接字符串。

安装在该计算机上的sql server更多的是使用Windows身份验证。

和连接字符串是这样的：

hi guys
i have created a program that needs to connect to sql server 2008 database, and this program will run on 5 computers, that connected to one computer via a wireless modem[or router]
and the database is on that computer. so how should i set connection string in other computers.
one more thing the sql server that installed on that computer is on windows authentication.
and the connection string is like this:

<add name="PgDBEntities" connectionstring="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string="Data Source=192.168.1.101,1433;Initial Catalog=PgDB;Integrated Security=True;MultipleActiveResultSets=True"">
      providerName="System.Data.EntityClient" />;

当我尝试登录时我得到了这个错误=基础提供商在Open

上失败了所以我现在该怎么办？

when i try to login i got this error = The underlying provider failed on Open
so what should i do now?
