Deploying Java across a network was a little touch-and-go today. I had a point where Windows XP hung during the Installing Managed Software phase.
After waiting for about 20 minutes, I decided that the installation had failed. After removing the package from software deployment section of Group Policy, I rebooted the PC and ran the ‘Last Known Good Configuration’ startup option.
Thankfully, the next boot brought up the removing managed software dialog and Windows started normally.
