Hi Brian,

I've seen some similar problems before, On a WinXP system, if the XP 
firewall is up, I've seen it block the audio services.  Or even in general 
if there is a firewall inbetween the the laptop subnet (wireless router?) 
there could be blockage there.

On a MacOSX system, Some reason it doesn't support encrypted Venues. We 
have our own Bridgeserver here, The Powerbook couldn't see anyone due to 
the Venue had encryption on. Once I dropped encryption, it worked fine.

I hope this will help!
