Turning on/off Windows firewall on remote PC

While trying to fix one of our user’s IT issue remotely, I had to turn off Windows firewall which was set to Public. Users account does not have appropriate permission to make any changes to the system or run a command prompt. When I tried to make a RDP connection, it failed due to Public firewall is enabled.

I tried below Netsh command to turn off firewall on remote PC but it didn’t work.

Netsh –r 192.168.1.15 –u admin –p Password –c advfirewall set allprofiles state off

Then, I learnt about PsExec command. PsExec is a light-weight telnet replacement that allows users to run programs executable files on remote machines. First, you will have to download PSTools. Click Here to download it.

Once you’ve downloaded PSTools, unzip the file and copy PsExec to executable path. I copied file to C:\.

Run following command to turn off filewall on remote PC using PsExec:

C:\> psexec ComputerName –u username –p password cmd

  • ComputerName  - replace it with the remote computername
  • Username – replace it with your admin user name
  • Password – enter your admin user account password
This will open a command line for that remote PC; enter this command to disable firewall:

C:\Windows\System32>Netsh advfirewall set allprofiles state off

This command will turn off all firewall profiles. If you want to turn off only current profile, replace allprofiles with currentprofile. Type “ON” instead of “OFF” if you want to turn ON firewall.

I hope you find this article informative.

Fixed: HTC One M8 USB driver doesn’t recognized by Windows 10

Hi friends, recently I upgraded my Windows 7 OS to Windows 10 on my laptop. Everything was working fine until I plugged my HTC One M8 (Android) phone to laptop using USB cable. A message box appeared stating that it could not detect the USB device. I never had any problem when I was using Windows 7. I used to plug my phone to PC using USB cable and access phone storage as USB drive. I typed my query in google and most of the articles suggested that I should installed HTC Sync Manager and then connect my phone. Well, I installed the required application but it did not resolve the issue. Hence, I removed it. This is my 3 rd HTC phone and I started to find out how I can enable USB debugging mode on my phone.
