Can't access corporate website??

[Guest]

I have a weird problem at one of my clients. They have a webpage that is
hosted by an outside company and they sometimes have problems getting it to
display on the PC's on their internal network, but they can access any other
page on the web. If they type the IP address of their webpage they can
connect but then none of the page links work. Now after a few hours
everything will work normal again. We have talked with the hosting company
and the ISP and they are saying everything is fine and it must be an internal
problem. They have a 2000 server that was setup as a domain controller with
DHCP and DNS but AD was removed a few months ago and now it is basically just
used as a workgroup server. Could there be any DNS stuff left on the server
that is causing these problems?? I am not sure what is going on, any advice
is appreciated.

Any DNS stuff left on the server wouldn't be a problem unless clients were
still using it as their DNS server. This usually happens when an internal
domain is named the same as a public domain and local resolution does not
have records for the off-site host's IP address. When you get one that's not
working, do an nslookup for the web paage and see which server resolves the
address and what it is resolved to.

Hi

Where do those ex domain clients machines point for their DNS since the DC
has been demoted?

What forward zones are on the DNS server?

Is (or was) the client's internal Active Directory domain name the same name
as the external domain (website) name?

How are the clietns setup in IP properties? Are they using the internal
domain only, or a mix internal and external (ISP's) DNS servers?

Instead of the website you're using, I suggest to use OEx (Outlook Express

news.microsoft.com. This is a direct link to the Microsoft Public

to easily find, track threads, cross-post, sort by date, poster's name,
watched threads or subject.
