IP address change on DNS server

Hello,

I've promoted this new box to a PDC and taken it offline. It is currently a secondary DNS server. It will soon be the new AD/GC/Root server after the Win2k upgrade. I need to change the IP address to match a BDC (soon to be offline - backup) which happens to be the primary DNS server in our 'single' domain. Right now, way too many devices point to this address, that is why I need to re-use this address.

1. Can I just change the IP address of this secondary DNS server in NT?

2. Can I just change the zones from "secondary" to "primary" and then modify whatever DNS entries in NT?

3. If this actually works, and if I actually modify these entries, I want to upgrade this offline box to Windows 2000 Adv server and then bring it back online, will the other NT BDC's bark?

Any help would be much appreciated!

Brant, your plan looks solid.
1. Yes, you can just change the IP address in NT.
2. Yes, you should be able to change the zone type from "secondary" to "primary" and then edit it.
3. NT4 BDCs can exist in a Win2K domain as long as the domain remains in mixed mode. The AD DC will function as a NT4 PDC emulator as long as NT4 BDCs remain active. There should be no problem with your plan as long as the BDC you plan on using as a backup is taken offline before putting your new AD box online.
