I need a solution
I have some SEP clients that aren't updating, but it is only the virus definitions. I've attached three images from one of the affected clients. It claims the definitions are up-to-date and not corrupt. This client is also on 12.1 RU2. I did contact Symantec support as I was having this same issue with a few clients back on RU1 MP1, but the solution was to uninstall and reinstall, which isn't a very good solution. Does anyone have any ideas on this? I can upgrade a client using the intelligent updater. The recommend firewall ports are open and communication is happening otherwise. View the three image attachments I included.
