Lync Server Front End: Lost connection to the Web Conferencing Edge Server

Looking through the event log I stumbled across these 3 errors, logged at the same time every 5 min, after a reboot, every 15 min:

  • Event ID 41024 – Lost connection to all Web Conferencing Edge Services
  • Event ID 41024 – Lost connection to the Web Conferencing Edge Server
  • Event ID 41025 – Connection to the Web Conferencing Edge Server has been restored

Solution:

Disable IPv6 on the Front End server. You should disable it in the registry. Don’t forget to reboot after you make this change. Here is the MS KB article how to do this via the registry: http://support.microsoft.com/kb/929852

Hope it helps.
