I know this is an old discussion, but it came up when I was googling the interwebs for info on this.

1. You need to understand DNS.

2. You need to configure your server's network config correctly; i.e. do not register automatically with DNS Server

3. Delete all A records from DNS and re-enter as static

4. Disable listen all in your nework protocols

5. Set ip's accordingly

6. Set dynamic ports to nothing; i.e. delete anything there. Otherwise it will use it. 0 is not blank, it is "find something"

Should all work.
