Question

I just created my Visual basic application which connects and uses Sql database on my system.
And its working properly.

My Stupid problem is when i distribute my application to my friends on INTRANET/LAN, how do i make them communicate to my SQL Database on my system.

If this needs some study, kindly refer me the topics and references to learn.

Unless you and your friend are in the same windows domain, you’re going to have to turn off integrated security in the connection string:

"Server=10.0.2.88\SQLEXPRESS;Database=PlaylistTEST;User Id=myUsername;Password=myPassword;"

and create the login for the database:

In MSSQL Server Management Studio, expand server ->  expand security -> 
right-click on logins -> new login -> 
  sql server authenication: enter user and password, then 
  user mapping -> check off database that they will access and select roles down below.

and most likely enable mixed logins under SQL Server:

In MSSQL Server Management Studio, Right-click on server -> Properties -> Security -> 
        Server Authentication -> SQL Server and Windows Authenication mode 

and finally, possibly enable TCP/IP:

Programs -> MSSQL Server -> Configuration Tools -> SQL Server Configuration Manager -> 
         SQL Server Network Configuration -> Protocols for MSSQLSERVER -> 
         TCP/IP -> Right-click -> Enable
