network resources.

Thanks in advanced

Hello Nuno,

Do you use a single label DNS name like DOMAIN?
http://support.microsoft.com/default.aspx/kb/914050

Is this the only DC/DNS in the domain? Where was it migrated from? Please
post an unedited ipconfig /all from the server.

Best regards

Meinolf Weber

Hello Nuno,

Remove the 195.22.0.33 from the NIC settings, i assume this your ISPs DNS
server. This must be set as FORWARDER in the DNS management console in the
DNS server properties instead.

After that run ipconfig /flushdns and ipconfig /registerdns and reboot or
restart the netlogon service.

Also if not used disable IPv6 accroding to:

That's because there is no reverse IPv6 zone that has a PTR entry for ::1.
Did you disable IPv6 based on Meinolf's suggestions?

Once you've disabled IPv6 on the machine, and restarted, it should be fine,
that is as long as you have a reverse zone for 10.1.1.0 as well as a PTR
entry for 10.1.1.200.

Curious, what exactly does not work? Can you be specific, as well as
describe exactly what you've performed so far?

Did you remove 195.22.0.33 and disable IPv6 and restart the machine?

Also, if you see duplicate records with the same IP, this wouldn't cause
problems to stop internet access. However, to clean up this issue, you need
to force DHCP to own the records. Read the following on how to accomplish
this:

DHCP, Dynamic DNS Updates , Scavenging, static entries & timestamps, and the
DnsProxyUpdate Group (How to remove duplicate DNS host records)

My DNS server is also the DC of AD and the exchange server 2007 i have the
domain inoxxxx.local in the forward lookup zones and i still have also

i am all confused here
