System.ComponentModel.Win32Exception：找不到网络路径

Question

我将我的应用程序部署到iis.Its工作正常时，我给出了本地数据库的连接字符串

<add name="WPSConnectionString" connectionString="server=UXTSRV001\SQL2008;
   database=SupportPortal;Max Pool Size=10;uid=sa;pwd=password@123;" 
 providerName="System.Data.SqlClient" /

但是当我给出远程服务器的连接字符串时，我收到了错误

System.ComponentModel.Win32Exception: The network path was not found

连接字符串如下

<add name="WPSConnectionString" connectionString="server=MYSERVER;   
database=UISupportPortal;Max Pool Size=10;uid=MYUSER;pwd=PASSWORD;"  
providerName="System.Data.SqlClient" />
