Thanks for that Marc.

I have confirmed that disabling NetBIOS over TCP/IP stops windows from
issuing the NBNS queries, and wait time for the page refresh drops
from the approx. 3 secs to around 1sec.

I guess mac osx naturally doesn't implement a NetBIOS name server
either and therefore has the same issue when working with windows?
