Windows firewall is not disabled automatically by Symantec Endpoint Protection (SEP) 12.1, and this blocks communication between SEPM and SEP.When user manually disable Windows firewall,communication between SEP and SEPM returns.
SEP has no green dot at the tray and is showing offline both at SEPM console and SEP client interface.
SEP only disabled Windows firewall one time and when PC restart, Windows firewall is back
This is about setting in SEPM firewall policy.
Windows Server 2008 R2 standard,64 bit.
