nslookup server fails

I've setup a new sbs2011 server and everything seems to be working fine. Expect for one thing. When we try to login to www.hyves.nl a call is being made to secure.hyves.org. At this point the login fails and the page errors out. If I check the URL with ...
nslookup secure.hyves.org 192.168.1.2

Open in new window

... I get the error "server failed". If I ping the URL it says "can't find host". If I try the same thing with ...
nslookup secure.hyves.org 8.8.8.8 (Public Google DNS)

Open in new window

... it works.

How can I solve this? Every other webpage is working just fine.

I'm guessing 192.168.1.2 is your sbs2011 server and the DNS server used by your machine?

You need to figure out why hyves.org is not answering correctly when you query for secure.hyves.org.  Is your sbs2011 server using forwarders for that domain?  Root hints?  Does it host the domain?

Need a little more info...

You say you have REDIRECTION from www.hyves.nl to secure.hyves.org
I think it is the problem, because the device, which redirects, does not resolve "secure.hyves.org" properly, most probably from internal network.

How is this redirection created?
Is it client-side redirection on web page? In this case PUBLIC resolving must work.
If it is server-side redirection on IIS. then server must resolve properly.

It all depends of where "secure.hyves.org" is located:
- if it is on LAN with the same server as www.hyves.nl, then you must add A-record to local DNS, which resolves secure.hyves.org to 192.168.1.2 or whatever local IP
- if it is on PUBLIC side, then your local DNS must have an A-record with secure.hyves.org having public IP (...or resolve to public)

www.hyves.nl is a social media site in The Netherlands comparable to facebook, much smaller of course. Very popular in The Netherlands. So the site is not hosted on our server, it just a public website. If I'm outside our network, for instance using my smartphone or internet at home, the login succeeds. If I'm on a workstation connected to the network the login fails. So one way or the other the name isn't resolved in an ip-address.

Gotcha... so you have nothing to do with hyves.nl or hyves.org.  So, you need to figure out what's wrong with your DNS server.  Are there any errors in your eventvwr in the DNS Server eventlog?

192.168.1.2 is indeed the SBS2011 server. It's the only server in the network and acts as the DNS, DHCP etc...

Are there any errors in the DNS Server log?  Also, is your server set to use forwarders or root hints?

I do have some information messages that could be related.

Error 5504

The DNS server encountered an invalid domain name in a packet from
193.0.14.129. The packet will be rejected. The event data contains the DNS
packet.

I would suggest you switch your DNS server over to use fowarders.  Ask your ISP what their caching nameservers are that you can use.

Thank you. I added a forwarding address and now it works. Man how I missed this is beyond me.

Thanks!
