Corp. is the host for our AD services. We are a plant across a frame circuit that has a 2k3 server for file sharing. Last night our circuit died, (corp. does all dhcp/wins/dns also), my clients worked for some time then expired. I updated the hosts file to do name resolution. How could I keep my clients from expiring? If I have a local 2k3 server, how can it provide validation to my clients instead of depending on corp.?
