On our office VLAN we see numerous (about 10 percent of all traffic on all switchports) NBNS "UNDEFINED" queries:
We also see normal NBNS queries for hostnames, wpad, etc. However we are unable to find any explanation for the "UNDEFINED" queries. Please can someone shed some light on this?
Many thanks :)
