Hi, relating to this problem:
http://groups.google.com/group/micr...564c3/5918d2148b6e9a59?tvc=1#5918d2148b6e9a59
We have a similar problem, only we have Windows 2003 server. We are
loosing connection intermittently througout the day, for a few seconds,
then, it goes back online.
We are not sure what's causing it. I believe it's a trouble with DNS,
although I don't have enough knowledge in this area, that's why I'm
posting this. The Internet provider already came in and confirmed that
nothing wrong with their line or anything.
In regards to that topic above, I looked at the properties that we have
in registries on the server, and there is no such a key
PublishedAddresses. Should I create it?
Thanks.
Vladimir

You should use the PublishAddresses value if DNS is listening on all IP
addresses. Make sure the published addresses are the internal IP.

Would you please post the unedited ipconfig /all from the DC?
 
Thanks Kevin for the reply.
In the DNS properties, on Interfaces tab, we have:
Listen On:
Only the following IP addresses:
10.0.10.15

which is our DNS server.
Does that mean that we don't need PublishAddresses value?

Here is the info you requested

I'm not sure if it's related. because we ARE running windows server
small business edition. and we do have Routing and Remote Access Server
that also runs DNS and WINS.
What can we do?
Thanks in advance.

It is related, since it is a RAS server when a RAS connection is made it
creates an extra IP address the you don't want registered in DNS. Follow the
KB article you posted, make all registry entries and manually create the
recommended records for the Global Catalog and LDAP IP address (that's the
(same as parent folder) record for the domain name.

Also, remove the three external DNS server IP addresses, your DNS server
will resolve external names using root hints or forwarders. If the
forwarders tab seems to be disabled, delete the "." (Root) forward lookup
zone. This will enable root hints and allow you to add a forwarder.
 
Also, Kevin,
How do we remove those 3 external DNS server IP addresses? We DID list
them as our forwarders, but somehow they show up as our DNS servers
besides our internal DNS server.
Thanks.

Have you looked at TCP/IP properties and they are not there?
If not, check this group policy:
Computer Configuration
-Administrative templates
-Network
-DNS Client
