We have around 4 DC's (Win 2008 Ent edition)
When we patch them duing monthly schedule , any user who is working at that time see's outlook disconnection , Lync disconnections . login prompts from IE (if hthey are connected to intranet sites)
ot All DC's restart at same time , so at any point atleast 1 DC's ia avilable.
All DC's are GC's and host DNS as well
I was hoping a DC going down should affect existing connected users since there will be other DC's availbe to serve
Is that correct
