1. You can disable firewall.

2. Impact depends on the network infrastructure. ( danger in public network, potentionally dangerous in internal network,...)

3. Give more information for more detailed answer.

The impact will be none, functionality wise. If you don't rely on Windows firewall for security (because you have external firewalls etc), disabling it will have no impact. We disable WF on all our servers because it is annoying and doesn't actually do anything for security in our setup (all servers are blocked off from external networks)

Hi,

If you have Windows Firewall disabled, then Windows Firewall cannot block network traffic any more, ports neither.

You should check all the computers which are acting as Event Sources for Windows Event Collector Services, any computer which has Windows Firewall configured could generate the error you are facing. In addition, IP sec policy could be blocking network traffic, too.

Hello,

Well, the Windows servers are inside LAN and DMZ, and we have Network firewalls dedicated to secure the networks.

And we have an application, CAT IT CM, that need to provide an opened configuration of the windows firewall, and the best way to do it is to disable and stop this windows firewall.

Then, inside the Configuration Panel, the windows firewall is disabled...
But the Windows Eventvwr Security show that the Windows firewal doesn't allow some ports and IP used by some CA executable files.
That's why, I need to stop the Windows Firewall, to be sure that the Windows Firewall doesn't disturb the CA executable files...
Regards,

And what about the "Windows Event Collector" service, "linked" with "WF" ? (dependancy)
Is there any impact to stop it too ?
