I very much doubt that :-)
Whether the server is a Mac or a polka-dotted unicorn (??), if you
can ping it, it pretty much has to have an arp association on the
client machine :-)
after you do the ping, does the arp table on the server have an entry
for the client ?
Well, I'm pinging from Parallels to the Mac, then doing the arp
command on the Windows/Parallels side. It says there are no entries at
all. I did use the -a flag. Sounds like maybe I'm doing it backwards?
It's the only way I can do it, since Parallels is my only functioning
Windows environment right now.
Sounds like you may be doing it right. I would be concerned that
Parallels manages the network from their "Hypervisor", and may therefore
"shield" (i.e. hide) such things as the ARP entries form the non-primary
OSes.
In any case, there was nothing in your description that said to me "must
be on same subnet", so as Luis said, arp is pretty much a loser once you
need to handle a routed (multi-subnet) network; I'd look more into his
suggestions of a script / file on the server which determines / holds
its own MAC address.
In another email, you said
If there is no reliable way to get the server's MAC address, I have a
problem.
The only way you can get even close to a "reliable way" is to run
something on the server itself - anything else will fail in some case
involving routed networks and/or proxy-arp and/or
multi-network-interface machines (which Mac address is to be used ?).
Even then, you can still hit problems if the MAC address changes (e.g.
servers running load-sharing or virtual network protocols).
