asked on Why some servers have to rejoin the domain again?
This is using MS W2K3 AD Domain. Recently, due to some reason, I got no choice but to change the DC's IP from .8 to .9. After that, I did some clean-up on the AD, DNS, to make sure that DC is using .9 for all the communications.
Recently, users stated to feedback to me that they are not able to logon to the domain. Secondly, I also found that few servers, have to be remove and then re-join to the domain, why? What went wrong? How to solve it? The DC was originally a physical server, and has since been converted to be a hyperv VM.
Shall I setup a second VM DC (a clean setup), to take over the above DC?

Typically I never virtualize DCs. Normally because it is so easy to just throw up another one. I would just build a new DC in the virtual environment like you said.
Also, I assume the DC was also acting as a DNS server? Is there any chance that the DHCP scopes are still listing the old address to clients for DNS? Or static entries on servers?

Hi MKline71,
The dc was virtualized from a HP physical server. It seems that there are 1 hidden NIC that holding on .8, beside the .9 on an "regconised NIC".
Shall I have to remove the hidden nic?

Remove the hidden nic and check how does it work:http://support.microsoft.com/kb/269155http://www.gfi.com/blog/how-to-remove-hidden-network-adapters-from-virtual-machines/

Make sure the networking is setup properly in the virtualization infrastructure too.
Thanks
