HI

I currently have 3 zone in my DNS Server( Zone A, Zone B and Zone C) . my client PC is pointing to Zone B suffx.
Will it look for zone A record if zone b does not have the records?
If no, how can I setup so that zone B will point to zone A records if zone b does not have the record
 
If the record is a match in any zone, dns will return it. No zone takes
lead over any other zone. The match is done with ownerName match.

Not unless zoneA is in the search list.

Add zoneA to the search list. IF you want it to look in all zones, you have
to add all zones to the DNS suffix search list.

It will if you have both zoneA and zoneB in the DNS search list. Which ever
one that it asks first that has the record it will resolve.
So if you have a record for machineA in zoneB and zoneB is in the search
list if you ask for machineA it will find it. But if you ask for
machineA.ZoneA it won't look in zoneB.
This only works for applications that use the search list in the DNS client
(e.g. nslookup and the system resolver) Dig and Netdig ignore the search
list in the DNS client.

Click to expand...
TCP/IP properties, on the DNS tab. Select "Append these DNS suffixes (in
order)"
Make sure you limit your list to local zones in local DNS server or it could
considerably slow resolution.
 
I have already put zone A inside the search list but I still got this problem that client PC cannot find LDAP service for another domain controller. The LDAP record is recorded in zone A while the client record is in zone B.

Does it matter ?
 
No.
DNS will figure out what zone to search based on the domain name of query.
If no local zone found or not in cache, then it will to recursive logic if
forwarders and/or root hints setup on server. If a local zone is auth for
the ownerName, then that zone is search for exact match or delegation, etc.
