Help needed!

We have in our sub-organization a subdomain ete.cez.cz. with primary
name
server on NW6 and secondary name servers on NW6 and HP-UX for this
subdomain. For other domains we have forwarder in upper domain cez.cz.

which is connected to ISP.
When DNS client looks up for a nonexisting domain/host in our
subdomain
ete.cez.cz or in an upper domain cez.cz the answer is correct as
follows:

C:\WINNT>nslookup
Default Server: ete1.ete.cez.cz
Address: 10.89.12.101

> nonexisting.ete.cez.cz.

Server: ete1.ete.cez.cz
Address: 10.89.12.101

*** ete1.ete.cez.cz can't find nonexisting.ete.cez.cz.: Non-existent
domain
> nonexisting.cez.cz.

Server: ete1.ete.cez.cz
Address: 10.89.12.101

*** ete1.ete.cez.cz can't find nonexisting.cez.cz.: Non-existent
domain

But when DNS client looks for a nonexisting domain/host in other area
the
answer is time-outed:

> nonexisting.other.domain.

Server: ete1.ete.cez.cz
Address: 10.89.12.101

DNS request timed out.
timeout was 2 seconds.
*** Request to ete1.ete.cez.cz timed-out

Here is the debug from NAMED console from simillar lookup:

Result is clear:
The response is dropped - why??????

The lookup realised via secondary name server on HP-UX is O.K. without

time-outs and droppings.

Many thanks for any tip.
