Is the new host connected to the same network?

can this DC ping the old DCs ?

Yes. it is pingable.

The thread doesn't relate to my problem. Actually, I only move the DC image to another VMware server. Nothing is changed.  

Tks

if you run dcdiag, are there any issues ?

The thread is exactly what error you are facing. What you are facing is not related to VMware in any way. Its about AD configuration.

I was told that the problem is caused for VM converter that can convert a Window AD Domain controller that is a lot of know issue for that....

I try to use Window backup on the converted DC to restore the Window 2008 backup copy but a lot of service cannot start.

Reboot the Window 2008 safe mode and want to use Window backup to restore, but it say Safe mode can't support Window copy. Do it mean restore AD and system store can be done through normal mode in Window 2008 R2 ?

Is there other way to move the DC (from VMware 4.1) to VMware 5.5 ?

Tks

I would suggest powering down the moved Vm and powering on the original VM.

If you need to move the DC you can use vMotion.

If neither of these are an option. Please upload the results of the following command so I can get a better idea of your AD environment

dcdiag /v /e >c:\dcdiag.txt

Yes, export / import to ovf template works. It seems that DC need to turn off before imaging.

We have another physical DC server that also need to prepare the VM. How can we do that ?

So what did you end of doing to correct your issue. Also you may find the following KB article helpful as it explains why Vmware Converter does not work with AD domain controllers.

I have to correct myself. You post made be due further research myself and found that you can P2V domain controller but very carefully..
