single and local access only SBS 2008 SP2

I am scratching my head with this problem.
Configuration
- SBS 2008 SP2
- Single:  dc, forest, server, dhcp, dns
- 1 network adapter, ipv4 and ipv6, static ip 192.168.1.200 and static ipv6, preferred dns server are 127.0.0.1 and ::1.

NSLOOKUP in SBS displays all root hint servers plus the following:

Default Server:  Unknown
Address:  ::1


If I enter server.domain.local in NSLOOKUP, it shows:

Default Server:  Unknown
Address:  ::1

Name:  server.domain.local
Addresses:  ..(snip ipv6 addr)..
                  192.168.1.200


In DNS console, it listens to both ipv4 and ipv6, "Disable recursion (also disables forwarders)" is checked, monitoring to simple query and recursive query are both passed in test.

Running RSOP in server shows no GP user preferences though a printer has been added.  This happens once ipv6 is enabled.  If there's only ipv4 in the nic adapter and totally disabled ipv6, the GP user preferences can be seen in RSOP from server.  The printer can also be successfully passed to XP during logon.

Please help.

This is normal...  However, add a reverse lookup zone in DNS and add a ptr record so that default server shows the actual server name instead of unknown.

Can you explain the actual problem you are encountering?

reverse lookup zone has already been added before.

The problem is the last but one paragraph that i mentioned "Running RSOP in server shows no GP user preferences though....."

do i have to add a PTR record for ipv6 in the reverse lookup zone?  I just don't see it there.

The ipv6 reverse lookup zone and the PTR record have been created, server restarted twice, but nslookup still shows the same things.

hmm...  can you post your TCP/IP settings?  and your reverse lookup zones?

Note:  I'm not 100% on this but...  can your change preferred dns server from 127.0.0.1 to 192.168.1.200 and retry nslookup command?  The error might be a result of not having a ptr for 127.0.0.1...

Thank you for the instructions.  I've changed the dns server to 192.168.1.200 before reading your mail, and nslookup is fine to recognize Default server.  However the printer settings in GP user preferences can't be seen yet after running RSOP in server though the GP user policies windows settings are appied correctly.

I'll close this question and raise another one for this specific issue of GP user preference.  Thanks NJComputerNetworks.
