My migration from Server 2003 to Server 2008 was going great until i just shutdown the last Server 2003 box that still had DNS running. Apparently DNS on my new Server 2008 DC was not really working and was forwarding requests to the old 2003 server. Once i shut it down outside requests and the entire internet stopped working until i turned that server back on again. Do i need to setup DNS forwarders with the IP of my ISP's DNS server for this to work or simply remove all forwarder IP's? i noticed on the old 2003 box it had no forwarders setup so that means it was using the root hints all along? internal host lookups work fine.
