bbwin on windows server 2008 - no data sent to bbdisplay

[pkc_mls]

 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 ?
