Can't access external website

02-02-2010

Hello
Our internal domain name is the same as our external website. I created a
host record pointing to the external site with its IP address and it has
worked fine. Recently, our website administrator changed the website format
from Windows to Unix and the IP address changed, so I updated the host record
and again it worked fine. Now, he created the whole website using WordPress,
and again, we can't access the external site. I have checked, and the IP
address is the same. I even tried creating a new delegation, but it still
isn't working. Is there something else I can do? Thanks.

He emailed me back and said that he went to the server that hosts our website and all the DNS information was correct. My boss is telling me that "it happened before to us, so it is very likely that it is our problem". Then I explained why it happened and that when I pointed the record to the new IP address, it then worked. I even called Network Solutions, and they said that as long as the site can be seen from the outside, it is an inside problem. I am not familiar with WordPress, so it is very difficult to troubleshoot a problem when I only have half of the tools. The error isn't even a "page cannot be found" error. It is either "The website declined to show this webpage" or "Under Constructionâ€ or â€œ403 Forbiddenâ€. I am thinking that if we are getting those errors, we must be getting through, yet we canâ€™t get in. If it was a website issue, why can you get through
from the outside?

In addition to Jonathan's suggestions, I would talk to the developer to see
exactly what he changed. He could have simply changed the hostheader, which
can cause all of this, or he may have incorrectly set a redirect in the site
design. It seems that all of this started with the developer changing
things, so that would be the first place to look.

I have already spoken to the developer, and he claims that he looked on the website to see if anything was set up incorrectly, and it wasn't. He also claims that as long as he can get onto it from home, it must be my network. Would the suggestions you made pertain to WordPress? We didn't have this problem when it was in Windows format. Is it possible that as well as a record pointing to the external site, I need a reverse lookup as well?

Marie,

I assume you are only talking about getting to the website by using
"www" in front of it, and not without using "www" such as,
http://domain.com.

If you are trying to get to it without the www address, that is a
little more involved to configure it and requires installing IIS on
your domain controllers/DNS servers, which I don't advise.

Since you have the same external and internal name, I need to know
exactly how you created the internal "www" record so it can resolve the
external IP address.

In the meantime, read my blog on this scenario and common problems
associated with this scenario. It explains everything regarding the DNS
side of it, which *appears* to be the problem, or simply you are trying
to get to it without the www in front of the domain name.

Split Zone or no Split Zone - Can't Access Internal Website with
External Name or external site with same name.

Curious, can you tell us what the domain name is? I want to make sure
you have the IP correct, and to see if there are any CNAMES going on at
Netsol's end.

Also, in a command prompt, can you ping www.domain.com? If so, what IP
address does it reply with?

One other question, it would be helpful to also see an ipconfig /all of
the server. I'm starting to think the server may be configured with an
external DNS address in it's IP properties.

Thanks for posting the info. I can access the site, however it's slow
loading. When I ran an nslookup on it, it's slow responding, too. It even
timed out on me on a couple of occasions. I'm kind of surprised that
happened considering it's Netsol's nameservers.

As for AD, apparently things look ok, and you are not using an outside DNS
server. But what I can suggest is to make some minor changes, and one major
one.

As for the minor changes, all of your DCs point to .252 as their first DNS
address. I would actually suggest, as well as many other engineers, to point
to itself as the first address, and then to a partner DC. Using three DNS
servers is really not necessary. THe client side resolver service (even on a
DC/DNS), will check the first. If the first has a NXDOMAIN response, meaning
not found, it lookst at that as an answer and will not look further in the
list.If the first response is no response, or NULL, then it will remove the
first from the eligible resolvers list, and move on to the second one.
However getting a NULL will only be after a time out period before it goes
to the second. If the same happens on the second, the time out the client
side resolver will wait will have expired. Therefore having three of them
doesn't matter because it may never see the third one due to the client side
resolver timing out waiting for a response.

The major change suggestion is for the multihomed DC, APPSRV1. A multihomed
DC is defined as a DC with more than one NIC, IP and/or RRAS-VPN installed.
This causes havoc with DNS registrations for the DC and consequential issues
with AD communications and functions. It is a well known issue. You have two
options. 1) Move RRAS/VPN role to another non-DC (member server), and either
disable one of the NICs or team it up with the other, or 2) make necessary
change with the operating system regarding DNS registration, including
registry changes.

Please read my blog on this issue, with much more detail regarding why this
is necessary.

Back to the website problem.... Are there no other records created for www,
whether a delegation (which would look like a yellow folder called www), or
any other records? I assume you are trying to get to it by using
www.empressems.com and not simply http://empressems.com, correct? Using
http://empressems.com will not work.

Marie:
I am seeing exactly the same issue for my customer with an in-house Exchange
Server. When I revised their website and hosted it on a different server,
exactly the same result-they cannot see the website from the office, and
experienced network support inside office cannot resolve. Did you find a
solution to this problem?
thanks,
Marcia
