Answer 1

Use common Server for handling SQL Database. If your application is not developed for common Database Server system then you should replace your SQL instance name in the connection string with Client PC SQL instance name before deployment/creating setup file. Use App.config file for establishing connection with SQL. like below..

<add name="Yourconnectionname" connectionString="Database=YourDBname;Server=Change with Client Server Instane name;UID=clientid;PWD=clientpwd;" providerName="System.Data.SqlClient"/>
