A quick test would be to do something like this:

nslookup <ip address of known machine> <ip address of DNS server>

It should return the hostname of the first IP address machine.

You can also manually set the DNS of a machine to just that DNS server and try to access machines on the network by their hostnames.

In addition you can also use Resolve-DNSName if you are using powershell.

Are you currently having any issues on the network?

Thanks

On top of what the others have said already, you can also turn on DNS debug logging to log incoming and outgoing DNS queries and replies. You can use nslookup; particularly with the debug options setup:

.\> Nslookup
set d2
testquery

You can use Wireshark or another packet capture tool to monitor DNS traffic.
