Hi All,

We have Windows Server 2003 DNS running. Actual we changed with our ISP to
hidden primary. The Forward Lookup Zones work fine. Only the Reverse Lookup
Zone don't wantet to talk to the DNS of our ISP.

We got the Subnet xxx.xxx.xxx.96 255.255.255.240
I made a Reverse Lookup Zone 96/28.xxx.xxx.xxx.in-addr.arpa
but when the DNS of our ISP ask our DNS, our DNS forwarded the question to
the DNS of our ISP

Here is our zone file configuration:
;
; Database file 96_28.xxx.xxx.xxx.in-addr.arpa.dns for
96/28.xxx.xxx.xxx.in-addr.arpa zone.
; Zone version: 2004082307
;

@ IN SOA ns.domain.de. hostmaster.domain.de. (
                                2004082307 ; serial number
                                900 ; refresh
                                600 ; retry
                                86400 ; expire
                                3600 ) ; default TTL

;
; Zone NS records
;

@ NS ns1.isp.de.
ns1.isp.de. A xxx.xxx.xxx.xxx
@ NS ns1.isp.de.
ns1.isp.de. A xxx.xxx.xxx.xxx

;
; Zone records
;

100 PTR host.domain.de.

Does anyone knows problems with this configuration? Or is this configuration
wrong?

Any advice would be nice.

Tanks,
Kristina
