I have a desktop PC. Its name is Srh-PC. Its operating system is Windows 7 Professional Service Pack 1 64-bit. It is connected to SRH-NETGEAR as wireless for internet. Its IP Address is 192.168.1.10

I have a smartphone LG G3. Its operating system is Android. It is connected to SRH-NETGEAR as wireless for internet. From the web interface of router, I can see that the smartphone has been given IP Address as 192.168.1.6

The issue is from the desktop PC (192.168.1.10) I cannot ping the laptop (192.168.1.5).
Similarly from the laptop (192.168.1.5) I cannot ping the desktop PC (192.168.1.10).
But from the laptop (192.168.1.5) I can ping the smartphone (192.168.1.6). Similarly from the desktop PC (192.168.1.10) I can ping the smartphone (192.168.1.6).
How can I solve this problem?
UPDATE:
Couple of things I forgot to mention which may be helpful in resolving this issue:
I work from home for a company. Both the desktop PC and the laptop are provided to me by the company. I use both of them for company's work.
Both the desktop PC and the laptop have the same Domain COMPANY.LOCAL
where COMPANY is the name of the company which I have not shown for privacy reason.
The full computer name of desktop PC is Srh-PC.COMPANY.LOCAL
while the full computer name of laptop is Srh-HP.COMPANY.LOCAL
where COMPANY is the name of the company which I have not shown for privacy reason.
When I login to desktop PC or laptop, I use the same User name and password. The User name is COMPANY.LOCAL\srh
where COMPANY is the name of the company which I have not shown for privacy reason.
Windows Firewall is turned off for Domain network location settings
, Home or work (private) network location settings
and Public network location settings
on both desktop PC and laptop.
There is another software Bitdefender
which is installed on both desktop PC and laptop.
I can make Remote Desktop Connection from desktop PC to laptop using its IP address 192.168.1.5
. Before making connection Bitdefender asked my permission to make the connection and I said Yes.
I cannot make Remote Desktop Connection from desktop PC to laptop using its name Srh-HP
. Remote Desktop Connection gives me error message that it cannot find the computer "Srh-HP".

Disable or reconfigure the Windows firewall on each computer.
If you want to allow only PING, then you’ll need to allow ICMP Echo Request packets.
