This is a question from the automated practice test that comes with the
Micrsoft MCSD boxed set of books. I think it's wrong.
You create a Windows Service that connects to a SQL Server data source
when a user logs on. You find that because of network problems the
client application disconnects from the data source. You need to change
the Windows Service so that it checks the connection every five minutes
and reconnects to the data source if the connection is broken. You need
to add this functionality to the Windows Service, so you uninstall the
service add the functionality. You then rebuild and reinstall the
service. However, when you run the service, you cannot see the newly
added functionality. Which of the following tasks should you perform to
view the new functionality? (Choose one correct option.)
1) Update the existing installers, and then rebuild the service
application.
2) Debug the service, and find out why you cannot view the
functionality.
3) Remove the existing installers, add new installers, and then rebuild
the service aplication.
4) Verify the permissions for the security context, and then rebuild
the service application.
Answer: 3 (???)
What does removing the installers do? If you look at the code in the
studio-generated installers, it just consists of basic properties like
the service name and the account. Why would removing the installers and
adding identical installers have any impact at all?
