NETBIOS NS: Type Unknown
This protocol anomaly detects an invalid value in 1) the QUESTION_TYPE field in the question section, or 2) the RR_TYPE field in the resource record header.
Extended Description
If the value of the QUESTION_TYPE field and RR_TYPE field in NetBIOS name service packets are outside the range specified in RFC1002, the packet would be treated as a protocol anomaly.
