Problem with dns statistics

[Gé Janssen]

Hello,

A few weeks ago, I demoted a Domain Controller. (also a DNS server). I now
have one domaincontroller/dnsserver left.

Since that time, my dns-test is going crazy.

Can someone give me some things to search for? Is there a debugging mode?

Regards,

Gé Janssen


This is what I did so far:

As you can see, the DNS Teests executed takes 450 seconds.

There were 6 DNS failed, but they are resolved using "testip" in the BB-Hosts.

Al the names in BB-Hosts are tested trough nslookup:

# cat bb-hosts | grep ^[1234567890] | awk '{print $2}' | xargs -n 1
nslookup > /tmp/nslookup
All hosts that did not resolv are "testip"

My logging reports the folowing:
