Hi Kyu,
Apologies if it has been translated. Here is my previous response in english (I've added additional steps):
Can you try the steps below and see if it turns the firewall back to on:
- On your search bar, type "Command Prompt" and select Run as administrator
- Type the command:
NetSh Advfirewall set allprofiles state onand press Enter
You may also enable the SMB1 File Sharing Protocol:
- Go to Control Panel > Programs > Programs and Features > select "Turn Windows features on or off" on the left pane of the window
- Check the feature "SMB 1.O/CIFS File Sharing Support" then click on OK
- Once done, perform a reboot and check again.
If you want to do it via powershell, here are the steps:
- On your search bar, type "Windows PowerShell" and select Run as administrator
- Copy and paste the command:
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" SMB1 -Type DWORD -Value 1 –Force - Close the powershell window and perform a reboot to apply the changes
If the issue persist, you may also perform the additional steps on this article and see if it fixes the issue: https://windowsreport.com/fix-firewall-cant-cha....
I hope this helps.
