You probably need to configure SQL Server with SQL Server Configuration Manager, make sure TCP/IP is enabled:

In your connection strings, you're using "Integrate Security=true". Do you know what that means?

That means whatever account is running your code is the account that is used to attempt to login to SQL Server. If that account doesn't have permissions to login to the server, the login is going to fail.

So, it appears that the user running on the first workstation does have permissions to the server and database and the user on the second machine does not.

The only time using Trusted Connection makes sense is when you're in a domain environment (using Active Directory) and the users are part of a group that has permissions to the server and database.

Your description and code suggests that Active Directory is not being used, so the best option to use is specifying a Username and Password in the connection string. These two values would have to be entered into your application via a dialog box, and then combined into the connection string to use to connect to the SQL Server.
