Hi, I've got a new (about 1 month) server 2008 box out at a clients and periodically it stops serving DNS requests. Restarting the DNS Server service has no effect but running a manual "copy from server" in the root hints tab of the DNS server resovles the issue. There are no enlightening events in the logs to shed any light. Has anyone else experienced this phenomenom at all? It's the first live 2008 server I've deployed and if this is a known problem then I could do with having the resolution clear to avoid/solve in the future. IPV6 is enabled as Exchange 2007 is installed, it grumbled about it not being available, and it is the IPv6 addresses that appear next to the IPV4 addresses when the "copy from server" button is hit. Regards Greg
