Have a general question about Active Directory Logon. We have a WIndows 2008 server acting as domain controler. Also have another 2008 server running active directory services as well. I can see that some computers when they logon are logging on to our domain via the 1st server (primary I call it) and some onto our secondary. My question is that sometimes when we do updates and restart our primary server some users need to logoff and log back on during that time. Because of that restart (and the fact that they were logged on via the primary) is that why they are having to logoff/logon? Or should it be a more seamless transition and perhaps something isn't set quite right? If that is the way it should work I am fine with it, just want to make sure.
