I get "Login failed for User" error in visual basic connection to sql-server. This error occurs when I move my database from one PC to another.
I solve this problem by using same "PC-name" & "User-Name" of my old PC in new one.
How should I avoid this I mean I want to use different "PC-name" & "User-Name" on new system. Note that my Sql Login credentials are same in both New & Old PC still it won't let me login.

    Hi @Habib ur Rehman ,

    > I mean I want to use different "PC-name" & "User-Name" on new system. Note that my Sql Login credentials are same in both New & Old PC still it won't let me login.

    Agree with Erland. In addition, please make sure that the user account used in connection string is created in SQL server logins under security folder in new PC .

    I'm not sure that I get this. First you say that you want to use different user-names, and then you say that your SQL login credentials are the same in both?

    Are you using Windows authentication or SQL authentication? What does your connection string look like?

    If you look in the SQL Server errorlog, you will find more details on why connection failed.
