DNS Problem



  • 1. DNS domain and host records with the same name
    I'm trying to add the following hosts to my DNS hierarchy: services.mycompany.com staging.services.mycompany.com I've taken following steps: 1. Created the zone "com" 2. Create the domain "mycompany" under "com" 3. Create the domain "services" under "mycompany" 4. Create the host "staging" in the "services" domain When I try to create the host entry "services" in the "mycompany" domain, I get the following error: "A domain of this name already exists. To create a record with this name, select the domain and then create the record." The problem is that I want to treat "services" as both a domain and a host. Can't DNS differentiate entries by their type? Is there a way to create the entries above? Thank you.
  • 2. DNS Delegation
    Hi, We currently have our forest empty root domain and a child domain dns hosted on a non-windows 2000 server. Here is what we want to do. We are planning to move the dns to the windows 2000 domain controllers for the domain to take advantage of active directory replication. IF it were a single windows 2000 domain then I think it would be straight forward. Just create secondary dns zones for the domain on the windows 2000 server and then after it is populated change the currect dns server to point to the windows 2000 server as the primary and start of authority. But in our case we have two DNS domains. The parent forest root 2k domain and a child domain. We have two domain controllers for each domain. My thought was since they are at the same location just have the child domain controllers take over the dns for both the parent(forest root) and child domain. But then I was wondering can I still have active directory integrated dns since we now have two domains although it will be on DNS servers (domain controllers) of the child domain. The other way I suppose I could do this is delegate the DNS domains to the domain controllers in their perspective 2k domain controller. Now I would be installing dns on four servers instead of two. Sorry this is so long but I wanted to give as much detail as possible.
  • 3. DC has no DNS Name
    I get a 414 error in the DNS Event Log on my only Domain Controller that states: "DNS name is a single label hostname with no domain (example: "host" rather than "host.microsoft.com"). You might have forgotten to configure a primary DNS domain for the server computer. For more information, see either "DNS server log reference" or "To configure the primary DNS suffix for a client computer" in the online Help." Obviously on a domain controller I cannot go into the Network Properties under system and reset those. I have also run the script from Knowledge Base Article - 257623 and that did not seem to work (the proper settings seem to be set in the registry) I am having several strange problems such as Exchange won't start because it says it cannot contact my domain controller, I get errors when I run DCDIAG: "SERVER's server GUID DNS name could not be resolved to an IP address. Check the DNS server, DHCP, server name, etc Although the Guid DNS name (7942fd1f-bf54-4105-a1d5- 45f6824bfbab._msdcs.domain.com) couldn't be resolved, the server name (SERVER) resolved to the IP address (xx.xx.xx.xx) and was pingable. Check that the IP address is registered correctly with the DNS server." and when I run NETDIAG it says there is no host name. Does anyone know how to "reset" the host name and/or primary dns name for a domain controller?
  • 4. Internal DNS
    Hi all. Need a little help here. I have a web application that calls the url on another server to populate fields in the call. Both servers are on the smae LAN. Only problem is that I cannot browse internally and when the app calls for the info it uses the DNS that I have set up which points to our external(public)ip addresses. Also have a PIX Firewall. Do I have to set up an additional internal DNS server that serves up the URLs with internal addresses to solve this problem? Or is there another way to correct this? Thanks.

DNS Problem

Postby William Oliveri » Wed, 02 Jul 2003 00:41:29 GMT

Hi all,

  We have a small W2K Active Directory network with the DNS Suffix as
mydomain.com where mydomain is exchanged for our domain name.  This is fine
and all is working well.  However, we have an off site mail server which is
not part of our AD domian and where the mail server address is
mail.mydomain.com.  Whenever we set the DNS Server IP in DNS settings on the
client to our DNS Server they can get to the internet fine but cannot
retrieve their email and I believe it's because the suffixes are the same.

  Is there anyway in DNS to tell the DNS Server that when a request comes in
for mail.mydomain.com to forward that request to the mail server?

Or Is there another way to solve this problem.

Actually it's "exchanged for" mydomain.com  <-- the AD domain name includes
whole dns zone/domain name.


Perfectly normal -- add records BOTH in your External DNS and your
Internal DNS (each manually and separate) for this "mail" server address
and MX record.

Possibly but more likely because you haven't added the Mail server
(properly) to the Internal DNS servers.

BTW, your clients SHOULD/must be set to use those INTERNAL DNS
servers -- the internal servers forward to the Internet (ISP or recurse from
root themselves) for ZONE they cannot cover locally.


Not really.  Forwarding is done on an all or nothing basis.  If the server
is authoritative
(covers) a zone then it will not forward for records IN THAT ZONE.

But you don't need that.  Just add the records in both places.

Hi all,

I received the following warning in a WIN XP PRO..."The

Does anyone know how to fix this problem??

Luis, this error indicates that the XP machine could not 
register its IP address with the DNS server.

The most likely causes are either the DNS server is not 
allowing Dynamic Updates or the DNS server is not 

If the XP machine is not hosting services or a member of 
an Active Directory domain, you can ignore it.

I didn't say that it was incomprehensible.  I said that it 
was _self-contradictory_.  I also said that until you provide 
an accurate problem report, the best that you are going to 
get is guesses that might be wildly off-target.  And, indeed,
that is what you have been getting.  (At least one of the 
responses has flatly contradicted what you wrote to be the case, 
because the poster has had to resort to guessing at what is 
actually going on in the face of your clearly erroneous 
description of your problem.  His guess might well be wrong
and his prescribed remedy incorrect as a consequence.  Moreover,
two other responses have prescribed remedies that directly 
contradict each other, because their authors happen to have 
made different guesses as to what your actual situation is.)

As Jonathan said, we can (sort of) guess what the fellow meant.
Jonathan and some others have been doing this long enough to
make sense out of statements that really make no sense in and
of themselves, because they KNOW what must be true,
and can GUESS what is likely meant....

This does not substitute for clarity or accuracy of the report,
espcially if the problem is difficult to resolve or even diagnose....

Our internal DNS domain.com is the same as our external

must include the WWW as setup in DNS to go out to the 

How can I make the domain.com (without the WWW) resolve

Add a record named www in your internal DNS zone and give it the IP of your
external web site.

If you use regedt32 it is a pretty simple and straight forward process, you
just navigate to the the registry above then click edit, new Value, type in
DnsAvoidRegisterRecords in the Value field, then choose REG_MULTI_SZ as the
type, when you click OK it will bring up the Data field and type
LdapIpAddress, click OK and your done. Then you can delete the (same as
parent folder) records with the private addresses and add one for the public
address you need.

I am tring to do this w a dlink router 604 which has a public ip and private IP , Also I have Windows 2000 server setup as DNS ad integrated with ip also it has a name server and WWW / Exchnage runing on i
This is my setu

My DNS / Exchange / Web server has addres
Under Virtual server, I allowed SMTP port 25, DNS 53 and www port 80 which oint to my windows 2000 server

If I get a request for mail from outside. The router will give the private IP as the holder for my MX record and it getting this from my internal DNS which is the same host

If you type nslookup and try to resolve to my domain name you will get my private IP 192.168.0.

If I take the router out and assign my public IP to the my DNS/Exchange/Web server, it works ok. So I think I am doing something wrong but it not obvious

2.Internal DNS problems and w2k DNS

I am running in mixed mode.  I have an NT4 BDC that runs DNS for our
websites.  I have Active Directory / DNS used for internal resolution
on a Windows 2000 domain controller and a Windows 2003 domain
controller (PDC emulator).

I am by no means a DNS genious, but every morning when I get back in
the office I am unable to resolve any websites that are listed on our
public DNS server.  I am able to reach those websites from an external
location (like home).  In otherwords, the public DNS server works

In order to resolve this, I simply clear the cache on the 2000/2003
servers and it is up and running again internally.

Any ideas on what could be causing this?

4.DNS Problems - BIND DNS server on linux, mainly windows XP clients

Hash: SHA1

Hi, heres the layout of the server (running BIND 8 on Slackware Linux 9.1):

eth0 -, in bind as a master zone called "linuxserver"
eth0:0 -, in bind as a master zone called "fredsserver"
eth0:1 -, in bind as a master zone called "jonysserver"

eth0 = first network card, "real" ip address
eth0:0 = first network card, a fake ip address (for an apache ssl virtual
eth0:1 = first network card, a fake ip address (for an apache ssl virtual

So the server has one network card, with three ip addresses.

there's also a "lan" master zone which resolves:

fred.lan to
james.lan to
server.lan to

My other linux computer (SUSE 9.0 Professional) can lookup all of the host
names correctly. However there are various Windows XP clients, all of which
can lookup linuxserver and *.lan, however none will lookup "jonysserver"
but one will lookup "fredsserver" - tcp/ip properties is identical apart
from ip address on each windows xp computer - Any ideas? I have checked
what a dns query returns from the dns server, and it is definately a
problem on the windows xp side. The virtual servers can be reached by IP
