This is a question from the automated practice test that comes with the\nMicrsoft MCSD boxed set of books. I think it's wrong.\n\nYou create a Windows Service that connects to a SQL Server data source when\na user logs on. You find that because of network problems the client\napplication disconnects from the data source. You need to change the Windows\nService so that it checks the connection every five minutes and reconnects to\nthe data source if the connection is broken. You need to add this\nfunctionality to the Windows Service, so you uninstall the service add the\nfunctionality. You then rebuild and reinstall the service. However, when you\nrun the service, you cannot see the newly added functionality. Which of the\nfollowing tasks should you perform to view the new functionality? (Choose one\ncorrect option.)\n\n1) Update the existing installers, and then rebuild the service application.\n2) Debug the service, and find out why you cannot view the functionality.\n3) Remove the existing installers, add new installers, and then rebuild the\nservice aplication.\n4) Verify the permissions for the security context, and then rebuild the\nservice application.\n\nAnswer: 3 (???)\n\n\nWhat does removing the installers do? If you look at the code in the\nstudio-generated installers, it just consists of basic properties like the\nservice name and the account. Why would removing the installers and adding\nidentical installers have any impact at all?
