CNR- slow response to DNS requests, dns.exe taking 100%
Hi, I'm very new to my current site ( <2 weeks) and I'm seeing some issues with their CNR. There is no one on site that can assist me with historical info on their implemenation.
Here's a brain dump:
CNR is running on a NT4 box with sp5. An IBM netfinity 4000 server P2-450 192mb ram also acting as a backup domain controller.
From the CLI, when I do "server version" I get "316". Version 5.0.2 of the GUI is installed on the box. There are approx 1500 dhcp clients and 1000 dns entries.
Admins are using version 5.5.1 of the GUI. I notice that none of them disconnect from the cluster when exiting the GUI tool.
DNS query response slows right down gradually over 6 hours during the day. A reload via the GUI of the DNS and DHCP seems to improve it to normal performance levels. When DNS is on it's last legs, dns.exe is taking up 80-95% cpu.
We've just had to reboot the box again and we're getting a little desperate. Any help would be appreciated!
