We are running ZDM7-SP1-IR1-HP2 on both clients and servers and NC 4.91 SP4 on our XP desktops. When a client machine is first logged in after a cold boot the Application Explorer icon appears briefly in the system tray then disappears and cannot be restarted causing the deployment failure of user associated applications.

After any subsequent logins the icon displays and apps are deployed as normal, this is an issue as to conserve energy our PCs are set to power down if not used for 1 hour.
