Does this error happen locally, or just when deployed ? Perhaps it's that the deployed site can't see the database ?

Yes, It seems the Issue is with your connection string. Please verify the connection string name, database Server Name, and User id and password.

I have checked it again every thing is alright i also connected with an other server but still is same problem. Dim con As New OleDb.OleDbConnection con.ConnectionString = " DataSource = ABC; InitialCatalog = XYZ; Username = sa; Password = sa" This is the line of code where error is acquiring.

OK - the first thing to do in this case, is to debug the code and work out what line blows up. The next, is to post the line and your connection string, etc., if you can't work out the issue.

It should look like con.ConnectionString="Data Source=Database_Server_Name/IP;Initial Catalog=DataBase_Name;Integrated Security=True;User ID=UserID;Password=Password;" ;
