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?
