[ASK] All blocking settings already disabled, but cannot be pinged

Question

Hi All,

I have my laptop with below info
OS Name: Microsoft Windows 10 Home Single Language
OS Version: 10.0.19042 N/A Build 19042
OS Manufacturer: Microsoft Corporation
OS Configuration: Standalone Workstation
OS Build Type: Multiprocessor Free

I already tried to turn off Windows Defender firewall (Domain profile, Private profile, Public Profile is Active), turn off Windows Security settings (Real-time protection), turn on file and printer sharing (Private, Guest or Public), however I still cannot ping this laptop from same segment IP (ie another laptop/phone).

This laptop able to ping other IPs, however when trying to ping this laptop, there is no response like unreachable or request timed out.

I use wifi adapter to get DHCP IP, and it works well browsing internet.

Is there any advise ?

Many thanks

Answer 1

maybe something block my traffic

If you have installed some other software or have something on your network that is blocking the traffic, then there is no way that forum users would know about that.

From another Windows machine, run Powershell_ISE and paste these commands into the script window. Set the IP variable to your pc's address. Run it and let us know the results.

$IP = '192.168.1.2'              # Put your IP here   
cls  
tracert.exe $ip   
$test = {  
    Test-NetConnection $IP   
    Test-NetConnection $IP -CommonTCPPort HTTP -WarningAction SilentlyContinue  
    Test-NetConnection $IP -Port 443 -WarningAction SilentlyContinue  
    Test-NetConnection $IP -CommonTCPPort SMB -WarningAction SilentlyContinue   
    Test-NetConnection $IP -CommonTCPPort RDP -WarningAction SilentlyContinue  
    Test-NetConnection $IP -CommonTCPPort WINRM -WarningAction SilentlyContinue  
}  
Invoke-Command $test | Format-Table  
  
  
  
  

It should look like this.

Answer 2

It is possible that your request is being blocked by other device, meaning you are able to send request but it is being blocked in the other side.
Also check your router and network configuration and verify nothing blocking this request on the way.

Answer 3

Public Profile is Active),

If you are on a public network, many things will be blocked because that's what you should want on a public network. You should not want some unknown person in a public place like a Starbucks or a library to be able to access your laptop.

Are you actually on a private network? What are you really trying to accomplish? File sharing?

If you trust the network you are on, change its WIFI settings to Private.

To temporarily disable the firewall, you have to click on the tab of the active profile.

Hello Windayaniachmad,

I would recommend to check the next:

• Is there any other software such as VPN, antivirus, etc? Could you try to run a "Clean Boot" by running msconfig.exe and disabling services that are not related to Microsoft?
• IPCONFIG shows the same for both clients as subnet mask, gateway and DNS
• Is it working pinging the IP, and not with hostname, or both?
• Have you run TRACERT <destination IP> from the working client, to see where the hops stop?
• Running NETSTAT -R shows you anything different on the failing client and the working client?
• Can you check the HOSTS file in C:\Windows\System32\drivers\etc to see if there is anything unusual ?
• Have you tried to run a ARP table flush? (Running the command "arp -d” from an elevated command prompt)

Further than that I would also try to see in the Application and System events (Event Viewer) if you see any special Warning, Error, or sometimes information at the moment you send the ping (in both source and destination machines)

Hope this helps to narrow it down
