DNS doesnt resolve child hosts names without full dns name


R

Rich R

hi,

we have domain which has a child domain. the child domain
can resolve hosts names without using the whole dns name,
but the parent cannot do the same for its children.

example, on computer2.child.domain.com i can type ping
server1, and it find server1.domain.com.

on server1.domain.com i type ping computer1 and it
responds with something like computer2.com instead of
computer1.child.domain.com. instead i'd have to ping the
full dns name to get a correct response.

i'd like the dns to check it's delegated subdomains first
before looking outside, is this possible?

server1 is running windows 2000 AD and sits on the parent
domain.

server2 is running windows 2003 AD and sits on the child
domain.

thanks for any info

You'll have to configure the "DNS Suffix Search Order" on the parent DC.

On the Parent-DC:
Open the Properties of the IP-Protokoll of your Network Card. Click
Advanced.
Select the "DNS"-Tab. On the DNS Tab select the radio button "Append these
DNS suffixes" and "Add..." the suffixes of both the parent and the child
domain.
Reorder the suffixes with the arrows on the right side(entries higher in the
list are
used first) according to your need.

You need both domains in the DNS search list, on the DNS tab (append these
names in order)

Delegate the child name in the parent zone to the child DNS server (do not
forward) then forward the child to the parent.
