Hello Pat,

Reverses lookup zone with 0.in.addr.arpa is default and ok, forward
shoudln't have it, also ok.

The other both records are not servers in your domain?

Any additional zones in your domain where they belong to?

Can you ping them?

Best regards

Forward look up doesn't have a recorfd for 0.0.0.0
Reverse lookup has 0.in.addr.arpa zone and the name server is listed
there.
xyzd-7100.xyz.domain.com on the one server and
xyzd-8200.xyz.domain.com on
the other dns server.
Thanks,

Hello Pat,

The 0.0.0.0 you can ignore if i am correct. And records for
192.168.103.0, if that subnet is not used, just delete. Do you have
a record for 0.0.0.0 under the forward/reverse lookupzone, if yes
for what machine name?

Best regards

Meinolf,

How can we use X.X.103.0 or 0.0.0.0 these are reserved for network
only they shouldn't show up when I nslookup xyz.domain.com we
never had any machine with an IP adrees ending in 0

Hello Pat,

I assume the entry x.x.103.0 is from an old machines connected to
the domain some time ago.

If you open in DNS the reverse lookup zone with advanced view
enabled you have also the 0.in-addr.arpa, which belongs to your
domain name 0.0.0.0, which is created by default in the same way
like the 127 and 255. I assume that belongs to your 0.0.0.0

Hello Meinolf,

All are DCs but only 1.1 and 1.114 are DNS servers.
I don't have the tool that perfomed DIG. That was forwarded from
another
admin.
But if I run NSlookup for xyz.domain.com I get the same address
listed
as in
my post. 0.0.0.0 and a 103.0. I deteted the records on Friday
and
they
haven't came back thus far. I was thinking that it may be a
problem
with 2 of
the teamed nics.
We have recentley been upgrading drivers and firmware using
Insight.
Since
the bad address haven't re reregistered is there anything else
that
could
cause these entries?
Thanks again for the help

Hello Pat,

Are your DNS servers the DC's? Can you post the command you use
so that we can maybe reproduce it? I think even with DIG it
should only result in answers that are from your domain.

When performing a DIG we noticed a couple of malformed entries
in
DNS
that
might be causing lookup issues for the proxy server. Any Idea
what
would
cause this
We only have 4 domain controllers. 192.168.103.0 and 0.0.0.0
have
me
concerned.
Each server has 2 nics and they are teamed
