|My active directory keeps dropping its connection to DNS. As long as I keep AD open, it works fine. However, if I close it, and don't use it for some hours, it will not load up due to a dns problem. Also, when I use the NSLOOKUP command, I get the message, "Can't find server name for address 192.168.0.x: Non-existent domain."|
When I reboot, it clears up.
DNS and AD have previously been working fine, for some years - so this just started happening in the last few weeks.
DNS and AD work fine on my backup DNS/WINS server.
Appreciate any help or suggestions!
