Domain Problems

[Guest]

We have a small domain called www.somename.co.uk and our website site is the
same name, i can't see my website on my internal network i can only view it
externally from another PC that is outside my network. What could the problem
be?

Its a Windows 2000 Server network with Windows XP cleints.

Cheers

We have a small domain called www.somename.co.uk and our website site is the
same name,

Surely you didn't really name your DOMAIN
"www.somename.co.uk"?

Didn't you name the DOMAIN: somename.co.uk

i can't see my website on my internal network i can only view it
externally from another PC that is outside my network. What could the problem
be?

All the DCs register the name of the domain so
there would be a conflict if you named it as you
reported.

Assuming you named the domain without the WWW,
your users can resolve the web server by typing that
www, but no by typing the "bare domain name."

You must add the WWW server A record to the internal
DNS server -- you should also add any/all other external
resources for your domain that you wish to resolve by
internal clients, e.g., FTP.somename.co.uk, smtp.somename.co.uk
or whatever else you have "out there."

Its a Windows 2000 Server network with Windows XP cleints.

You have a DC right?

Sorry, just read what i wrote, you are correct the domain is somename.co.uk
the WWW is not present. Yes i have a DC and installed is Windows 2000. Could
you just explain what you mean by adding the WWW Server A Record to the
internal DNS server?

thanks again.

Sure, if you clients will lookup www.domain.co.uk
then they must find the www record in that zone.

You must list it on the internal servers used by the
clients (correct used by the clients in fact.)

Just add the www record as an A (Host) record with
the address of the www server. (Right click, add host...)

You cannot expect the clients to find that record if it isn't
listed in the (version of) the zone they check.

And internal clients must check SOLELY with internal
DNS servers.

thanks..

Right i have tried what you told but it still doesnt work i am affraid, so i
am not sure what else to do, any ideas?

Then you did something wrong because this MUST work.

Are you clients setup to use your Internal DNS SOLELY?
(On their NICs.)

If you type on the DNS server (paste in the text of the answer):

nslookup www.domain.com Srv.IP.Addr.ess

Then the same from the client.

Paste the text of the answers in and please don't send graphics
or type them in by hand -- I need to see the output.

Include your IPConfig /all from both Server and a Client.

You TOOK OUT the info I needed to see below.

Go back and check your zone (somename.co.uk) for the www
record.

This MUST work.

Do the clients use the server with this zone directly?

Do the clients use a DIFFERENT server (without the zone)
for the alternate DNS server (that doesn't work unless the
two servers return ALL the same answers.)

i just didnt fancy my domain information wacked out on this forum thats all.

Ok. We will help if you ask us.

Also note, there is nothing wrong with obfuscating the
domain name or some such, but it is the numbers that
I generally need to see.

Of course you could send them to me directly -- I prefer
that we do it in the forum so that everyone can learn, or
even help if I don't know the answer.

Let us know when we can help.

ok no problem then, i will send what you want because i havent got a clue
about this if i am honest.

*** fileserver.Somename.co.uk can't find www.Somename.co.u

Ok, then how about doing these lookup:

nslookup -q=soa Somename.co.uk 10.100.100.100
nslookup -q=NS Somename.co.uk 10.100.100.100

[Show me the output if you don't know for sure.]

We want to prove that the DNS server can resolve
both the SOA (zone header record) and the NS servers
for it's zone Somename.co.uk

1) If it can resolve those others but no the www, then you
put the WWW record in that zone incorrectly.

You might have written the whole name (without a
termininating dot) which ends up as:

www.Somename.co.uk.Somename.co.uk

Or you might have made some other typographical error.

The www record needs to be an A record. (It might
be a CNAME but that is a wee bit trickier to get correct
so let's just make sure it is an A record.

If you can't find that error, open up the DNS MMC and
send me the screen-window picture of the record you
think you defined showing in the data pane with the
zone showing on the right. You can email it to me
rather than obfuscating.

2) If it can't even resolve those SOA and NS records
then there is something wrong with the zone or the server
itself, perhaps:

1) Zone name is wrong
2) DNS Server is stopped
3) Server is running a "personal" firewall that blocks

You might be resolving local names with broadcasts so
maybe it never worked.

What is this 10.100.100.5 machine?

The server is an internal DNS client and must itself
use ONLY internal DNS servers, but that isn't part
of your client problems.

If 10.100.100.5 is an internal DNS server then the
clients can use it too -- as long as it gives the same
answers as 10.100.100.100.

 

[Guest]

The output I got from the other NSLOOKUPS are below, it’s the same for client
and server. The 10.100.100.5 is an alternative DNS server, which is my
exchange box. I have created the A record in the Forward Lookup Zone under my
Domain name: Somename.co.uk

There are loads of host records in the DNS>Forward Lookup Zones

Somename.co.uk, which are client PCs and SOA and NS records, there is also a

folders called,

_Msdcs
_Sites
_Tcp
_Udp
www

and inside the www folder I have created the www A record. Could you explain
how to create an www A record just in case I have done it wrong or point me
to a website where I can find out? Does the A record need to be the www
folder or does it need to be in the first directory with all the client PCs
and the NS and SOA record.

Did you JUST create this A (since your last report and test)?

Or was that "www" A record there before?

If it is new, did you try it? Did it work?

It pretty much has too, since your DNS server is working
for SOA and NS -- so if the WWW A record is there it
must work.

 

[Guest]

no the A record as been the www folder since, when i created it three days
ago and its doesnt work.

When i created the record i think i am typing the wrong stuff in, like what
IP address do i enter.

The records says the

parent domain = www.somename.co.uk
Host = SOMENAME (is this right?)
IP = i have entered the IP address of the internet site (is this correct?)

Maybe i have the A record in the wrong location, i have never done this
before so i wouldnt know. Thanks for help, very much appericiated.

 

[Herb Martin]

There is a difference between "doesn't work" (at all)
and gives the wrong answer.

If you nslookup that record then it has to work if it is
in there correctly AND the client can lookup other
records in that same zone.

When i created the record i think i am typing the wrong stuff in, like what
IP address do i enter.

The address of the www server.

The records says the

parent domain = www.somename.co.uk
Host = SOMENAME (is this right?)

No. Somehow yo uhave made a SubDomain named
"www" rather than an A record, or a host named
"somename".

Delete everything related to WWW, make a NEW
A record with host name "www".

Refresh server.

Go to any client and type:

ipconfig /flushdns

(You don't need the above for nslookup, but you do
for ping and IE or other regular applications.)

IP = i have entered the IP address of the internet site (is this correct?)

Why would you do that if you wish the WWW to be the
name of your INTERNET web server?

You put whatever address you wish in there, but that is
what the clients will be using.

Maybe i have the A record in the wrong location, i have never done this
before so i wouldnt know. Thanks for help, very much appericiated.

In your zone (main zone) internally you want a SIMPLE A-Host
record named www.

The full name will be www + the zone name.

Ok i will try and do what you said and see if i can get it too work, as
regards to you above advise, so basically create the A record in my main zone
and the full name will be wwwsomenamecouk because it doesnt allow you to add
the .

So the record will be

Parent Domain = Somename.co.uk
host name = wwwsomenamecouk
IP = IP address of web server

 

[Herb Martin]

Yes.

the .

No. The name will be www.somename.co.uk You add
www onto somename.co.uk .

Why ever would you think the "."s would DISAPPEAR
from the domain name?

(The dot between www and the domain name is implied by
the dialog box. In DNS files etc, an unterminated name is
appended with the domain name by default. Were you to
be able to put the "." on the name it would be an full name
with just that value "www." There is no such domain.)

So the record will be

Parent Domain = Somename.co.uk
host name = wwwsomenamecouk
No.

www.somename.co.uk

IP = IP address of web server

That's where you want it to point, right?

 

[Guest]

I knew you were going to say that about the missing "." but in the host text
box where i want to write www.somename.co.uk, it won't let me add the "." but
i guess in that host text box i just add www and then it will add it to
somename.co.uk(parent domain) to become www.somename.co.uk. I will give it a
try and let you know.
