Well obviously the IP -> MAC conversion is working correctly, or you wouldn't be able to connect at all. What must be missing is the hostname resolution. You either need to place it in a hosts file on Windows, or setup an internal DNS system.
PS, you do know that ARP cache entries expire, right? Unless you're doing arp -a immediately after pining the host in question (or making some type of connection to it) then it won't have an entry in the ARP cache.
