bbwin on windows server 2008 - no data sent to bbdisplay

Hi all,

I try to set up bbwin on windows 2008. the only network packets I get from the bbwin server are like this one : 1.2.3.4 224.0.0.252 LLMNR Standard query A yourfirstbbdisplay

my bbwin.cfg works fine on windows 2003, but 2008 doesn't seem to work fine.

did anyone already experience this ?
