I checked on my machine and I got the same problem between two Erlang nodes.
The Java node connects fine because it doesn't care about a long name being
a FQDN or not.

In my case, the problem was that I have the Home edition and I'm not
connected to any domain. I fixed it by editing
c:\windows\system32\drivers\etc\hosts and adding an entry like
192.168.1.2 mypc mypc.localdomain

This lets me connect Erlang nodes that use mypc.localdomain as -name.

My guess is that it is something similar in your case, please check this
file and see what it contains.

regards,
Vlad
