Have client with a SBS 2011 Standard, running Exchange and about 15 client computers. All running Symantec Endpoint Protection. THis morning all clients lost connection to server with alert Symantec Endpoint .... The client will block traffic from ip address 192.168.x.x. for the next 600 seconds (ip address of server).
I have ran SEP scans on server and does not catch anything. How can I troubleshoot this?
