I think my DNS / AD is screwed up. My client has been reporting some weird behavior in their network. Suddenly, mapped drives or network based apps are not accessible. Some are reporting that they are not getting an IP address via DHCP. In fact, they are getting nothing - not even the default machine address.
I saw some events in a workstations logs (didn't collect it for this report - I will if necessary).
I looked at the DNS on the domain controller and I saw this (see attached): There is a forward zone for the domain but not one for the active directory (sorry, I don't understand this part very well so I might be using the wrong nomenclature). So, there is no '_msdcs.domain.local' zone.
Not sure but something tells me this is a big deal. Can you help me confirm this? And, if so, what can I do about it?
