Successful One way ping

I have an interesting problem.  From my domain server I am UNABLE to ping one of our clients.  But from the client computer I am able to ping the domain server.  How is it possible that its a one way ping success but not from the other way.  What could be the issues.  I am pinging using the IP address only.  This is a Windows network and the client computer is Windows 10.  I am almost 100% positive that the client is the problem.

ping is a two way process, send and receive the echo request
the client's firewall has not been configured to accept echo request (ping) 2018-09-17_23-21-53.png check the enable checkbox on the client.  Default is to NOT accept icmp 4 echo requests (ping)

ping and tracert both use ICMP packets.  If you tracert from both systems, it's likely that at some point the tracert will fail and that'll be where the ICMP packets are being dropped.
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

you may check the list of started services. if 'Server' service is started at your client's computers they can be seen in the network and they should be available for ping as well if firewall allows it.

Use Windows MTR to ensure all IPs in your chain are working.

Sometimes IPs drop ICMP packets + MTR still provides a good interface to ICMP (ping/traceroute) data that's easier to debug connection problems at a glance.

If one IP drop 100% of all packets, this is a good starting point.

This trick works a good bit of the time + if many IPs in your chain block ICMP packets, you'll have to start looking at Firewall rules on ever machine in the chain.
From my domain server I am UNABLE to ping one of our clients.  But from the client computer I am able to ping the domain server.
Comes right down to firewall rules. Check that client you cannot ping. Most likely, something is blocking or dropping ICMP traffic. Just because you can ping from a system does not mean that you're going to be able to ping it.
