Swap Win2k Domain Controller IP addresses

[SirCam]

I have 2 Domain Controllers in Win2000 AD (SP4) domain which need to swap IP addresses (there are several more DCs in the domain). If I unplug the network cable from A, re-IP B to A's IP, reregister with DNS, then change A's to B and reboot, will that work? The theory is B will be ok, and A should reregister with DNS and WINS on bootup.

What do you think?

I'd like to understand the reasoning on why you need to do this?

I would do it this way.

Set server A to use DHCP (temporarily). Change Server B's address.

On Server B execute:

IPCONFIG /FLUSHDNS
IPCONFIG /REGISTERDNS

Change the IP on Server A and execute:

IPCONFIG /FLUSHDNS
IPCONFIG /REGISTERDNS

When changing the IPs you will also need to look at the DNS settings to ensure the systems will still have access to internal DNS servers.



I hope you find this post helpful.

Thanks for your reply.

Can Domain Controllers in 2000 be configured to use DHCP? If so, that's just crazy enough to work...

yes they can. You normally would not want your servers using DHCP,note that it is only an interim step.

I hope you find this post helpful.
