Is there a way to resolve NIC service IDs (the GUID assigned to each hardware NIC) from the command line?

If you mean the actual GUID that the machine has assigned to your nics, use netsh from the cmd line (you may need to start the Wired AutoConfig and/or WLAN AutoConfig services first).

For wired NICs:

netsh lan show interfaces

And for wireless NICs:

netsh wlan show interfaces

The output will include the GUIDs of each network interface.

I assume you're referring to MAC addresses?

If so, the arp command is your friend. arp -a will show all the addresses your OS knows about. arp -a <IP> will display just the MAC address of a specific host. If you don't have a GUID on a specific host, pinging them should pick it up. That being said, this will only work on hosts on the local network. Packets sent to/from external networks will utilize the MAC address of the local gateway.
