Hi,
Have you come across any issues in Lync 2010 where the front end server shows event log 5719. The effect is that the server “drops” of the domain. All services carry running. This basically means that all IM and all telephony stops working. I have had this on 2 pool front end servers and also a SBS. A reboot fixes the issue but as we use lync companywide for telephony a reboot isn’t particularly great! The issue seems to appear again after a period of time e.g it maybe 4 weeks before it happens again.
Thanks
Matt
