I have a Fedora Core 4 box which I joined to my Win2003 ADS domain using winbind. I also managed to configure named as a secondary name server to accept zone updates from the Win2003 domain controller DNS service. The Fedora box also doubles as a Samba server to which the Win2003 file areas are backed up each night in the small hours.

Named is configured to log to two log files - one which logs issues (event.log) and the other which is a straight query log (query.log).

Everything has been running fine for about a month, but now when I look in /var/named/chroot/var/named, I see the query.log is going haywire, and is fillling up with about 200 requests every second from 127.0.0.1 all similar to the following:

04-Nov-2005 23:04:32.339 queries: info: client 127.0.0.1#33202: query: dc1-winsvr03.domain.local IN AAAA +

These are interspersed at a much lower frequency with messages similar to the following:

04-Nov-2005 23:04:32.466 queries: info: client 127.0.0.1#33202: query: _kerberos-master._udp.DOMAIN.LOCAL IN SRV +

I've tried the simple stuff, such as restarting named, rebooting the box, but to no avail. There is nothing in event.log to point to a problem, but I can't help thinking that this means something has gone wrong somewhere!

Can anyone tell me a) what is causing this, and b) how I stop it without rebuilding the box from scratch please (which is the only way I managed to cure it last time).

Many thanks

Have you made sure that on the linux box, the /etc/hosts file has a hard coded entry (IP Hostname) for the windows server, and conversely on the Windows server, make sure it's HOSTS file has a hard entry for the linux box? This would prevent either one from having to do a DNS lookup to get the IP address for the other.
