I have A lync Implementation where database deployed on SQL cluster but when moving sql instance from node to another all Lync Clients go into "limited functionality" and never go out of it till the user sign out and sign in is that a normal behavior
SQL instnace moving from node to another take less than one min
another issue I am using enterprise pool with 2 lync frontend and I am using DNS load balancing when a server go down and clients was connecting to it the clients take about 5 mins to fail to the second server , is that normal ?
