Windows 2000 AD is crashed

Hi All,

I am using Windows 2000 server with AD, I assumed that my server is crashed and I need to reinstall the AD to new server, what is the best way to migrate all of AD from crashed server to new server.

Have more than one domain controller and it's fairly easy.  (Also, more than one Global Catalog server).

And/or make sure you have frequent and known good System State Backups.

I have one more domain controller, but how to make it become the root of AD when the original root server is crashed.

I usually backup the System State, but it can't be restored to another server which have difference hardware configuration.

What do you mean by root?

The key AD services are:

Global Catalog
FSMO roles

DNS can be on multiple machines
Global Catalog can be on multiple machines
FSMO roles can be spread out and when and if necessary, "Seized"

As leew explained, Windows 2000 AD doesn't have a Primary Domain Controller and one (or more) Backup Domain Controller(s), it is a multimaster architecture (not master-slave, like NT 4) per se so, unless you have more domains and you meant to say you lost the only domain controller of the root domain, you will not see any problems.
You CAN migrate AD to new hardware, I have done this many times at DR testing.

Install a base OS then restore system state. Machine will fail on first boot - probably. So, boot from Win2k CD and chose SECOND repair option. This will repair Windows and you will be able to boot.

Like I said, I have done this many times and it works a treat.
