We just changed our DNS IP for our Intranet to a new IP and how can we get DNS to replicate this change further? When we ping the site it still comes up with the old IP.

External or internal?
DNS in the internet needs some time until fully replicated, so give it a day. Ther is not a lot you can do.
If it is your own DNS it should work more fast, but even may interferenced by caching.

So, if nslookup on a machine resolves to the wrong name, try ipconfig /flushdns to empta the cache. Internal DNS settings should apply at once.

If more than one DNS is involved, make sure that the settings are replicated and can replicate (for MS DNS by AD integration - otherwise ou have to tell the DNS how and which whome they should replicate).

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Two places you can do this on the servers, first is the DNS server its self.
In the DNS Manager, right click on your server and pick clear cache.

then you can also use the command prompt for your servers local cache.
IPCONFIG /flushdns

The Ipconfig /flushdns can also be used on your clients to help clear out old settings as well
