It seems like it happens on a rolling (but random) basis,

and the outages last about an hour or so. It's just (as far as I know, anyway) the one website, which leads me to believe this is a simple configuration issue that I'm just not catching. My domain users have no luck with the IP address or FDQN. DNS is handled internally via SBS 2008, and I have access to 3 machines - the DNS server itself, a domain workstation, and a non-domain

However, if they replace the internal DNS (192.168.1.3 that is also DC/DNS IP address) with their ISP DNS, they can access the website. All inside computers with the internal DNS have this problem.

The most likely reason you can access nyrp.org by name and not IP is the web server is using host headers, aka many domains are being hosted on one server with the same IP address and the only way the server knows which web site it should serve is by the host name in the request.

Following Follow Firewalls Hello all. I have a weird issue. Our company has an externally-hosted web site. we can get to it from outside the company network but not within. This has been working but stopped a few days ago. For some weird reason there is an entry in our internal DNS server for the external IP address of the site. I have not made access external website any firewall changes or anything like that. We can access other external web sites just fine except our own. Does anyone know what might be causing this?

Can you, from within your network, ping your website by name, i.e. www.mycompany.com? When you do the ping, does the command return the correct IP address for the site? If you ping from outside your network, do the IP addresses match with your internal results? If you do not have ready access to an outside machine from your office, you can also use on of the DNS sites, like www.dnsgoodies.com to do the DNS lookups for you, or use nslookup pointing to an outside DNS server. I suspect that the hosting company may have changed your public IP, either inadvertantly, or after sending a notice to the co

Now the website is accessible from outside the network but not accessible from inside the network. The ISP is the same and we can't access the website using our ISP. It doesn't resolve the dns at all. If i try pinging the website, it says 'host lookup failed', even nslookup is failing. When trying to access the website via the IPaddress, it refuses. The problem is in the ISP but i don't know how to solve it and the ISP isn't being very helpful. dns shared-hosting share|improve this question edited Feb 21 '15 at 20:49 PeeHaa 40.7k33133216 asked Oct 6 '14 at 11:55 David 7319 Try using google's DNS server? nslookup www.stackoverflow.com 8.8.8.8 –Charlie Vieillard Oct 6 '14 at 12:10 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted This often happens when someone is running authoritative and recursive DNS on the same servers. Which is why you should never do that :) It also happens when your local domain (Active Directory?) is the same as the domain you use at your hoster. Never do that. For example: if your domain is example.com then don't use example.com as your local domain. If you do then both your hoster and your own servers believe they are authoritative for that domain. Once the zone data starts to diverge you have this kind of weird problems. Instead use a subdomain of your domain name for your office, like office.example.com so that example.com can remain authoritative at the hoster. If you do have the same domain both locally and at the hoster then you have to manually make sure that the information in your local DNS server stays
