I ran the simple update across 70 computers, everything went fine except for 1 client(15 computers) that I have setup to push Remote Utilities out through ad. They updated, but the service got uninstalled. Anyone else have the problem, anyone know of an easy fix?
The Host service might have been uninstalled as a result of some antivirus software activity. You can add the Host installation folder to the exception list as described here and also submit a false positive report to your a/v vendor - this should help to resolve the issue with uninstallation and, hopefully, prevent it in the future. After you add the Host folder to the exceptions, you should be able to re-install Host via AD or try the solutions listed on this page.
