Final answer:
To find the MAC address on a Windows-based machine, use 'ipconfig /all' in the Command Prompt. Look for the 'Physical Address' entry in the output, which is the MAC address.
Step-by-step explanation:
If you need to find the MAC address of a Windows-based machine and you are not aware of it, the command-line utility to use is ipconfig. To do this, you would open the Command Prompt and type in the command ipconfig /all, which will display a list of all the network interfaces and their configurations. In the output, look for the 'Physical Address' entry which corresponds to the MAC address of the network adapter.
The command-line utility that can be used to ascertain the MAC address of a Windows-based machine is ipconfig. This utility displays the IP configuration of all network interfaces on the machine, including the MAC address. To find the MAC address, open the command prompt by pressing Windows key + R, type cmd and press Enter. Then, type ipconfig /all and press Enter. The MAC address, also known as the Physical Address, can be found under the corresponding network interface.
