Configuration for .Net application

I have very little knowledge of .Net programming, i got my software developed on .Net platform, Now i have installed the software but it prompts an error like Error in LibraryManager.SelectActive(),I have my database configured on local sql server and using windows authentication for it.THe xml configuration file is like <add key="ConnectionString" value="Password=;User ID=salman;Initial Catalog=LogoStick;Data Source=symbol;"/> with symbol as a DSN name.

Please tell me wher开发者_如何学Ce i am doing it wrong ???

your connection string is

Server =myServerName\theInstanceName; Database =myDataBase; Trusted_Connection =True; 

for the windows authentication

For refence you can check : Database Connectionstrings
