Lost connection to the Web Conferencing Edge Server

Problem
Error messages repeatedly logged, "Lost connection to the Web Conferencing Edge Server" from LS Data MCU.

Solution
I followed the advice here: http://msunified.net/2011/02/09/lync-server-front-end-lost-connection-to-the-web-conferencing-edge-server/ and disabled IPv6, but that didn't solve the problem.

It turns out this had to do with a previous OCS 2007 installation which left orphaned records in the Active Directory. This OCS 2007 installation was abandoned and never used in production, and therefore when Lync 2010 was installed it was not a migration. This is because the person installing Lync 2010 (me) had no idea that OCS 2007 was attempted to be installed on our system.

So i followed the advice here: http://blog.ucmadeeasy.com/2010/11/09/lync-server-2010-active-directory-references-and-how-to-remove-them/

and removed all references to the objects created during the OCS 2007 installation. This has gotten rid of the rampant error messages, and most likely has solved some other painful issues we've had that, which have been quite baffling.
