Scenario:
A Citrix Administrator has prepared two server OS machines to host applications. The administrator used Machine Creation Services to provision the server OS
machines. The server OS machines are part of the Windows 2012 Servers machine catalog. The Server 2012 Hosted Desktops and Applications delivery group is
assigned to the Windows 2012 Servers machine catalog.
The administrator was instructed to roll out Firefox as a hosted application and has installed Firefox on the master server OS machine named Win2012-Master.
Now, the administrator needs to update the server OS machines so that Firefox is available as a hosted application to only the Finance user group through
StoreFront or Citrix Receiver upon the next reboot of the server OS machines. The Finance user group is a member of the Server 2012 Hosted Desktops and
Applications delivery group.
Tasks:
Update the Windows 2012 Servers machine catalog to meet the requirements outlined in the scenario.
