IF AD server goes down across WAN

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.?

DCPromo the remote server, add DNS and DHCP to it locally which would then make the remote location able to function whether the link is up or not.

Additionally, configure both the local and the remote servers as Global Catalog servers, as some authentication functionality is dependent on this.

A better security option would be to deploy a DC on separate hardware from your file server, but if you are budget-constrained they can technically co-exist on the same hardware.
