Recursive Queries fail randomly

Discussion in 'DNS Server' started by Joe Palladino, Dec 6, 2007.

  1. I have two domain controllers on this network, both of them run DNS server.

    One of them NEVER fails recursive DNS queries. The other fails
    occassionally. Sometimes for 3 hours. Sometimes for 15 minutes. Sometimes
    its fine for a few days.

    In an attempt to fix this, I've uninstalled and reinstalled the DNS server
    service. I've demoted the DC and promoted it again using dcpromo.exe. I've
    removed forwarders and relied on root hints. I've tried new forwarders.
    Some times it looks like I've fixed the problem, and I pat myself on the
    back, and it breaks again at some random time with no warning.b

    I've turned on debug logging with all the options, but it honestly makes no
    sense to me.

    Any advice on how to figure out where the failure is occurring or how to fix
    it would be wonderful.
