Hello,
I have a Windows Server 2016 FTP server that was created October 2019. I know by default that ICMP is disabled. I enabled File and Printer Sharing (Echo Request - ICMPv4-In) for the Domain profile on the server firewall to allow ping requests from my PC and other servers on the network. Everything has been fine until recently.
I noticed that I can no longer ping to the server or from server. Although it does show enabled for File and Printer Sharing (Echo Request - ICMPv4-In) for the Domain profile, I noticed the File and Printer Sharing (Echo Request - ICMPv4-In) entry for the Private profile does not appear yet they both do for the File and Printer Sharing (Echo Request - ICMPv6-In) line item.
When running netsh advfirewall firewall show rule name=all in the command window it reflects the "NO" option in the "Enabled" section for ICMPv4 for Domain, Private, Public. I ran netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol="icmpv4:8,any" dir=in action=allow to try to "enable" it but when running the netsh advfirewall firewall show rule name=all command it still shows as No in the enabled field.
Coincidentally I noticed if I uncheck the box for "Enable firewall" setting in Symantec Endpoint Protection antivirus, I can immediately ping to and from the server without any problem. However, disabling the antivirus solution is not the true solution. Our other servers also have the same antivirus and the firewall setting is enabled in Symantec and I can ping to and from the servers without any problem.
What am I missing that it would show in the Windows firewall GUI that the Domain profile for ICMP is enabled but when running netsh advfirewall firewall show rule name=all in a command line it shows as "no" in the enabled field. Also why would the File and Printer Sharing (Echo Request - ICMPv4-In) entry for the Private profile no longer appear?
Thanks,
Roger
