La sessione di domande e risposte di oggi ci viene fornita per gentile concessione di SuperUser, una suddivisione di Stack Exchange, un raggruppamento di domande e risposte basato sulla comunità.
La domanda
Lettore SuperUser Dims vuole sapere come riaprire un Windows Firewall per approvare / negare la notifica:
I ran a program that caused a Windows Firewall notification to pop up, but I did not stop to think and quickly clicked “Cancel”. Now my program crashes due to network errors. How can I reopen or access the notification message so that I can select the option to allow the program to have proper network access?
Note
My question is not about how to add an exception to Windows Firewall because I do not know the exact “name” of the program that triggered the notification. Imagine I ran a script that started another script running, which in turn caused a program to run. Something in the process activated the firewall message that I unfortunately ignored.
Now the program is blocked and when I try running the script again, it malfunctions without any messages that would allow me to fix things. I need help to either find the program or to reopen/access the notification.
Come si riapre un Windows Firewall per approvare / rifiutare la notifica?
La risposta
Il collaboratore di SuperUser DavidPostill ha la risposta per noi:
How do I Find Out Which Program was Blocked?
Changes to the Windows Firewall rule set are logged in the “Application and Services” event logs. You can inspect the logs (which includes the date and time of events) to see what rules were added around the time you installed the program. With this information, you can remove the rule or create an appropriate exception in the firewall.
