Cannot make DNS Dynamic update work.

[pctest]

I have changed the "Allow dynamic updates?" to Yes for the zone type Primary in Forward Lookup Zones and Reversed Lookup Zones on the Windows 2000 DNS Server.

I have checked that the Windows 2000 DHCP Server has enabled the options:

- Automatically update DHCP client information in DNS
- Enable updates for DNS clients that do not support dynamic updates

I have checked that Scope Options have both 006 and 015 and the ip address 192.168.1.16 and domain name XXXX.com are correct.

NOTE: Server Options have nothing setup.

I have checked that the Windows 2000 client has the following TCP/IP settings:

General tab
- Obtain an IP address automatically
- Obtain DNS server address automatically

IP Settings tab
- DHCP Enabled inside the IP addresses
- nothing inside the Default gateways

DNS tab
- nothing inside the DNS server addresses
- Append primary and connection specific DNS suffixes
- Append parent suffixes of the primary DNS suffix
- Register this connection's addresses in DNS

I can ping to the dns server by name or ip address from the client machine.
If I issue the following commands on the client machine:
nslookup
set query=SOA
XXXX.com

the result is:
Server: Unknown
Address: 192.168.1.16

XXXX.com
primary name server = test.XXXX

If I issue nslookup test on the client machine,

the result is:
Can't find server name for address 192.168.1.16: Non-existent domain
Default servers are not available
Server: Unknown
Address: 192.168.1.16

Name: test.XXXX.com
Address: 192.168.1.16

I have issued ipconfig /registerdns on the client machine but nothing is updated and there is no error in the Event Viewer.

Thank you for any help.

I hope someone can help and I have these additional info:

Domain: XXXX
Full Computer Name of the server which contains both DNS and DHCP: test.XXXX and its IP address is 192.168.1.16


In the DNS panel:
under test
-Cached Lookups
-Forward Lookup Zones
- XXXX.com
- same as parent folder NS test.
- same as parent folder NS test.xxxx.
- same as parent folder SOA test.xxxx. (Primary server)
- dns A 192.168.1.16

-Reverse Lookup Zones
-1.168.192.in-addr.arpa
- same as parent folder NS test.
- same as parent folder NS test.xxxx.
- same as parent folder SOA test.xxxx.
Note: there is no PTR record for test or dns

Both test on the Monitoring tab passed.

Thank you for any help.
