Force DNS changes to propagate through AD with repadmin and dnscmd

In order to ensure a DNS change is propagated quickly through AD we should firstly perform replication between the DC's with the following command:

repadmin /syncall /AdeP

(The above will actually update all partitions)

Although this is not enough - we also need to instruct the DC you are on to poll the directory with:

dnscmd /zoneupdatefromds

You should now be able to see DNS changes / additions on the DC immediately.
