yes

arp -a x.x.x.x   (x.x.x.x is the ip address of the device) any device it'll work..

Note that arp -a only grabs MAC address within the same broadcast domain. Arp uses broadcast and would not traverse routers.
If your Network is 192.168.1.0/24, arp-a would only give you Mac addresses of devices your computer communicated with.

If a device is in the same subnet on your computer and arp -a command does not pull the MAC address, ping that IP address and run arp -a again

not sure what is the problem is
however run command prompt and type "ipconfig -all" and hit enter then it will list down all the details of all network interfaces.
Hope this solves the problem

So, there is not way to tell the mac address on the other subnet on a server that could communicate with other subnet, correct ?

Thanks

Correct
Unless you manage the switch on the other subnet, then you can grab the mac on its local switch
