In general, no. But sometimes yes.
1) If they have open NETBIOS, this can be fetched as a result of a NETBIOS
namserver query. See my nbtscan tool:
http://www.unixwiz.net/tools/nbtscan.html
2) if they have open SNMP, this can often be queried from the interface.
3) if a *neighboring* machine has SNMP open, you can often query the ARP
table to find it.
