Hello,
We are currently shutting down all server 2008 R2 DCs and replacing them with server 2012 R2 DCs. We have Lync 2010 with exchange 2010 as part of our infrastructure. When we stop the AD service on one specific DC lync will no longer expand the address book groups in lync. I have already stood up and shutdown 5 DCs without an issue with Lync. Can lync be tied to one DC?
