What protocol is mDNSResponder
The mDNS Responder Daemon (mDNSResponder) serves both as a DNS Stub Resolver, as a resolver for information published using multicast DNS (mDNS), and as a publisher of mDNS information. mDNSResponder monitors multicast traffic on port 5353, the mDNS port, to keep track of services advertised on the local network.

It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as unicast Domain Name System (DNS).
What happens if I disable NetBIOS
Disabling the use and support of NetBIOS can help to mitigate an attacker's ability to: poison and spoof responses, obtain a user's hashed credentials, inspect web traffic, etc. It's important to point out that NetBIOS itself is an API, not a networking protocol.

Vulnerabilities in Windows Host NetBIOS to Information Retrieval is a Low risk vulnerability that is one of the most frequently found on networks around the world. This issue has been around since at least 1990 but has proven either difficult to detect, difficult to resolve or prone to being overlooked entirely.
How do I know if NetBIOS is being used
Both your Active Directory domain FQDN and NetBIOS can be confirmed using simple command prompt commands. Type nbtstat -n and it will display some information. Under Name will be several entries: the NetBIOS will be one of the Group type.
