Currently, my copy of Symantec Endpoint Protection has its Proactive Threat Protection turned off. When I click the "fix" button, the following dialogue box appears:
"Symantec Endpoint Protection has requested new definitions from the management server. The problem will disappear after the server responds and the update is complete."
Upon clicking OK, nothing happens. Nothing has happened for the past few days concerning this state.
What can I do to resolve this---or, barring that, determine what the problem really is?
