Entering website name within organization in IE no longer resolving - 'Under Construction' message

I have a problem with a user being able to navigate to our internet website from inside our organization. Everything was working fine until I demoted a DC that was a DNS server and replaced it with a new server and added dns to that new server. I have flushed her dns cache but what she gets is 'site under construction' so if you flush it again it works for a couple of times then she gets this message again.
I am not an expert in DNS and I don't know what happened but I think that her computer thinks that the IP address of the new promoted server is the address for our internet website.
As an example:
New server: newserver.ourdomain.com
Our website: wwww.ourdomain.com
User enters ourdomain.com and instead of getting our website gets the 'under construction' message.

Anyone have any ideas?

can you do an nslookup to the server? and paste output here

Is the ip address gained via dhcp if so i would check dhcp settings.

Sorry! I think I solved it. I had check marked "use this conection's DNS suffix in DNS registration' in my nic configurationfor both the new DCs I had created. As a result a 2nd Host (A) entry was created where the Host field was set to (same as parent folder-ourdomain.com). These multiple entries were causing the issue when trying to navigate to our website.
Thanks for taking the time to read my question.

Just a retraction - the issue is resolved but it wasn't what we thought. The setting in the nic configuration did not control the registration of the 2nd Host(a) records. It did require a registry entry that prevented the DC from registering these records explained at this link:
