I am having the most baffling problem with one of my domain controllers. Windows Server 2008 Enterprise.
I has been working with out incident for two years. Then with little warning it fell off the network and refuses connection with any computer except for our main file server and the back up server. Those two devices information flows unimpeded. All other devices, including the other DNS simply time out.
I have tried the following:
ipconfig/flushdns
ipconfig/registerdns
located the entry for reverse dns
ensured that the ipv6 box was not cheched in the network properties
turned on and off the firewall
The cmputer can RESOLVE local computer address, just will time out. It cant even ping the gateway. It will not ping or connect EVEN using IP addresses.
Any help would be very appreciated. I am spinning my wheels now.
Thanks in advance.
