Enable ICMP or Ping request on Windows


If you ping a remote computer but fails, it could be that the firewall does not allow ICMP protocol.

Enabling ICMP or ping requests is quite useful for troubleshooting purposes but it could be also a security issue.

To enable ping or ICMP in Windows Firewall with Advance security, can be done via command line or using the graphical interface.

Command line is quite useful if the setting has to be done repeatedly or it has to be done on multiple machines.

Command line will also be helpful if a setting has to be enabled or disabled at times. Graphical interface is of course the easiest method if it has to be done one time but if the setting has to be done a couple of times then command line or scripting is definitely a good choice unless the person loves to click and click.

Enable Ping response using command line:
netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=allow

Disable Ping response using command line:
netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=block

If ping or icmp echo request is disable on the firewall and some program or any icmp or ping request to a specific device will always show "Request time out" as a response to the ping request.

If ping or icmp echo request is allowed or not block, then the device will response depending on its current state. For example, if the device is online then it will response or reply to the ping request.

Commands above should be run at an elevated command prompt.

The command prompt will show a message like: The requested operation requires elevation (Run as administrator).



Cheers..Till next time..

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')
gci d:\WorkFolde…

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username.
WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.
Why would you need a command line tool if there’s a GUI to check?
If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username.
