If you use an Active Directory, you can query the computer names from AD. Have a look at this article Working with Active Directory in VB.NET[^]. Even though it's VB, the idea is easily understandable

Even without knowing the real intentions of the questioner, this solution is only partial. In AD you can find only the computers (and some other devices) connected to the domain. There can be several other networked devices on a LAN you will not find in the AD. Assuming that you have an ethernet network, switches hold the most information about the devices the have encountered. Having the MAC addresses, you can try RARP to discover the IP, and if the device is in the DNS, you can retrieve it's name or get it with NetBios or WinS... if supported.

This is quite true. AD approach has limitations and using for example DnsQUery the results could be more complete. However if the OP wants computers recorded in AD I think querying AD would be the easiest way :)
