You need to use Sql Server Authentication
Use the code

C#

Data Source={server ip}\SQLExpress;Database=TestDB;User Id=UserID;Password=myPassword;

and Make Sure TCP/IP is enabled on server from Sql Server Configuration Manager.

You can't access remote SQL Server unless you made the required changes in the configuration.

Check these links-

Hope, these helps :)

The first thing to notice is that your connection string uses a local instance of SQL:

Data Source=.\SQLEXPRESS

The "." says "This computer".
You need to change the connection string so it uses the actual name of the PC server hosting the SQL instance, and almost certainly you should not be using "integrated security", you should be using "proper" name and password combinations.
