My company's website and my domain controller are using the same name.  While on the network I cannot reach my website.  I believe this is a DNS issue, but I do not know how to resolve it.  Please advise what I ened to look for.

Thank you

That would imply that they both would have a name like: www.mycompany.com
But I assume that is not quite true. Could you elaborate a bit?

I suspect that your router does not have "local loopback" feature.

This depends on the brand and model of the router.

It is a pain.

A common problem that some customers encounter when using a NAT router is that they want to be able to access their web site from within their local network, but their NAT router does not support "loopback" connections. This prevents them from being able to reach their own services, even though external visitors are able to connect.

To workaround this issue, you can put an entry in the HOSTS file(s) on your computers that are inside the LAN so they use the local (192.168...) address for the web site instead of the external (WAN) address.

Of, if the local network has its own DNS server, you could fix it there.

Create DNS records and point them to the internal webserver.  i.e.

192.168.0.2 www.example.com
192.168.0.2 example.com

Did you consider (if possible) to name the website www.hali.org?

Ah, sorry. I tried just hali88.org (with the same result).

Ok, what you could first to see if that works is go to: C:\Windows\System32\drivers\etc and open the hosts file there with notepad. Now add a line like this:
www.hali88.org        173.201.23.216

Safe and close the hosts file and see if that works.

Great! Remember that if there are multiple clients you can also add it in your dns server.

Oh, one more thing. Did you close the question correctly?

Well you accepted your own comment as the sulotion which means no points are assigned (I think they call it a refund). I assume that was not your intention.
The strange thing is I have seen that happening before, so perhaps there is a bug in the site.....
