DNS Problem

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.

Thanks,

Bill

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

is

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
the
root themselves) for ZONE they cannot cover locally.

in

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 
system could not register the host Resource Records (RRs)
for the following Network Adapter"

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 
contactable.

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 
name, domain.com.  When we goto our external website, we 
must include the WWW as setup in DNS to go out to the 
internet.  

How can I make the domain.com (without the WWW) resolve 
out to the internet also? 

hi,

you must ask your ISP  makes a record you A:

 @      A       IP (the same of the www.domain.com)

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.

Rodney, if Kevin's step by step doesn't help, re-read this article and it
explains how to do it. Just look for that specific section towards the
bottom. The article ALSO has a link on how to modify the Windows Registry
and may suggest to do that so you know exactly what you're doing.

Please read this aboutthat specific entry:

You probably don't have an A or CNAME record for
WWW

Sorry that was someone else who said he had an A
already.

This guy probably doesn't even have that.

the

I had him confused with a guy who had an A already for his
DomainName.Com but not the WWW.
