I have Active Directory Integrated DNS servers (about 7 AD DNS) which are transfering there zones to Secondary DNS. I noticed a trend where the secondady DNS servers chokes to a halt after every 12-13 days. On the Secondary DNS servers DNS event log there are several informational event ID 6522 and 3150 before I get Event ID 3000. After that I get multiple event ID 6522 and 9999 alternativley and continously for several days which then chokes DNS and hangs the DNS service. I have to reboot the secondary DNS servers for it to resume work. Anybody have an Idea what I can do to stop this trend from happening over and over.
Any input would be highly appreciated.
