Does anyone know where I can locate a blog or group for Live Communications Server discussion? I am attempting to allow our external clients and customers access to our Live Communications server thru our firewall. I am able to see the packets passing thru port 5061 successfully, but the clients are not able to connect via Windows Messenger. Any suggestions??

Are the clients using Windows Messenger v5.0? Is there a firewall at the client side? Have you seen this KB?;en-us;834469

I've not come across an LCS newsgroup or blog, has anyone else? Hey... perhaps you could start one :-)
