Servers can only ping to domain controllers and not to each other

Question

I have made my own test environment and I am having problems with pinging other servers from one server. All servers can ping to domain controllers and they get responded back. When I ping from a server to another server, I get following message "Destination host unreachable." Running Windows Server 2012 R2 all on servers and DCs

They all have static IPs

check if the windows firewall disabled (for testing) or allow ICMP Protocol. — scherard, Oct 27 '15 at 13:23
Do you have this on a different network with a firewall between? — Nixphoe, Oct 27 '15 at 13:29
"destination host unreachable" sounds more like a routing problem than a firewall problem. — Gerald Schneider, Oct 27 '15 at 14:16
DIsable firewalls and try again. If that doesn't help can you provide some ipconfig /all output for two systems that can't ping each other? — Ryan Babchishin, Oct 27 '15 at 14:21

Check to make sure all systems are listed properly in DNS. For your DC follow this, or check your install against it.

We typically assume that if you don't mention the version of OS your using the most current, if not don't forget to mention the version (2005/2008/2012) you'll get more specific answers that way.

ALSO check your hosts files: C:\windows\system32\drivers\etc\hosts The best way to find this is windows explorer and type the path, the etc folder is typically hidden.

I infer you're referring to ICMP (IPv4) echo-request, not to its ICMPv6 analogon.

It appears your servers are connected by a node that acts as a gateway in the sense of rfc792:

Destination Unreachable Message

     [...]
    Code
      [...]
      1 = host unreachable;
[...]
Codes 0, 1, 4, and 5 may be received from a gateway.  Codes 2 and
  3 may be received from a host.

that cannot (or doesn't) forward the ICMP echo-request.

More in-depth analysis of the issue would require more in-depth information about your network topology.
