View Full Version : DNS search order and server responds when it shouldn't

Hello all,

I have multiple DNS domains so I configured a domain search order on my
clients. If a client submits a request such as webserver11, it gets the
wrong domain in response.

For example, I watch this happen with Ethereal so I know it's not a client
cache issue. Client issues the command ping webserver11.

Ethereal sees the DNS request go to the DC/DNS server as
webserver11.dom1.com and the server replies no such name.

The client then requests webserver11.dom2.com and the server replies with
the correct IP address.

Unfortunately, webserver11 belongs to dom3.com and not dom2.com. The DNS
server is lying. The DNS server is authoritative for dom1 and has secondary
zones for dom2 and dom3. webserver11 does not exist in any zone except dom3.

Has anyone seen this before? Does anyone have good information on the
Advanced/Options settings in the DNS server properties? Which should be on
and off?

Any help would be greatly appreciated.

Thanks
