Re: DNS Root Hints Question

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Thanks SG

I looked at the article and can confirm that there wasn't any root zone
entry.

I'm still confused though.

There are 2 subfolders of folder Forward Lookup Zones:
_msdcs.'ourdomainname'.local and 'ourdomainname'.local


The data at the end of the subfolder chains is in all cases
<number>ourservername.ourdomainname.local. (example number [0][100][389])

So there's no reference to the DNS servers provided by the ISP there -
should there be?

If I right click the server name and look at Properties Forwarders there
does not appear to be any entries there.

I'm actually getting an error event (on server reboot only) that warns that
there are no Root Hints (or some alternatives) entries.

Gregg suggested using the copy from server command in the root hints folder.
This prompts for a server IP address. Which DNS server IP address should be
used please?

TIA

DON'T DO ANYTHING YET but have a look at this article

does it look familiar?

Jon,

What I meant is that the root hints are not needed for DNS lookups unless
you have no DNS forwarders. However, having the WRONG root hint server,
i.e., your own, will definitely cause errors.

Deleting your own server from root hints will kill the errors. Not having
any root hints is better than having your own listed. To fix the root
hints, delete any reference to your own, then click on "Copy from Server"
to put in the defaults.

When you use the CEICW to set up your Internet connection, it takes the
ISP DNS entries that you feed it and puts them in the correct place as
the forwarders. You can do it manually, but you should a wizard whenever
possible. Your understanding is correct.

When you run an "ipconfig /all" on your servers and workstations, you
should see ONLY the SBS' own LAN IP address for the DNS server, even if
you have two NICs. The CEICW will take care of that.

The wizard will set up the correct DNS entries for forwarders, but the
root hint problem sometimes happens if you set up SBS without having its
NICs connected.

DNS forwarders should be set up on all Active Directory enabled servers.
If you had an NT4 server, they were not needed. If you had a 200x server,
then your "ipconfig /all" results probably would have shown the ISP's DNS
servers, which would have been a misconfiguration.

You should install the support tools (CD2?) and verify with dcdiag and
netdiag that you have no errors.

If this is your first-ever SBS 2003 install, flatten and do it two more
times to learn it well.

Thanks for the reply Gregg

This is puzzling as this Roots Hint entry has definitely solved the
repeating error.

Looking at the Forwarders tab the only entry is "All other DNS domains"
which I presume is the default for adding a new forwarder i.e. there
currently aren't any set up.

I'm confused as the ISP's prefered & alternate DNS server IP addresses
were definitely entered when running the CEICW wizard and are still
there if the wizard is rerun. Are these not DNS forwarders or is my
lack of understanding of DNS now showing? Either way the server seems
to be functioning OK. Considering this is a brand new fresh install
shouldn't the wizard have configued these setting correctly? It seems
that were running OK with no forwarders or Roots Hint. BTW, Forwarders
weren't enabled on our old server.

What do you think?

Thanks for your help.

BTW, the only time the root hints would be used is if you have no DNS
forwarders set up.

You need to use the "Copy from server" to put back the defaults.

I deleted the only Root Hints entry of
'ourservername'.'ourdomainname'.local and this seems to have halted
the
literally thousands of ID 7062 errors that were being generated on
our
new and functional 2003 R2 Premium SBS server . Set up was through
the CEICW wizard.

Should we be running with no Root Hints? (Our old SBS2000 server had
about a dozen entries of the format Name: 'letter'.root-servers.net.
IP
Address: [external IP address] which seem to have been generated
automatically.)

TIA
