Hi Guys,
I am not sure if this is the right forum to ask such question or perhaps someone can divert my question. Any implication of a Windows 2008 server running on cold standby without any network connection for a period of time, tombstone issue? and the reason I asked is I am thinking of whether to do a 2 domain controllers replication where 1 fail and 2nd domain controller to take over or just to clone it as standby and plug in the network whenever the 1st domain controller fail. Appreciate any feedback.

Have 2 servers online all the time with replication, do bare metal backups nightly with the ability to restore to different hardware ( Acronis True Image, Storagecraft Shadow protect), Or virtualize your environment and use veeam to backup and restore the VM if the primary fails. If you leave the secondary domain controller offline and do not use backups you will have issues with user passwords and trust relationships with computers depending on the duration it's offline not replicating.

You need to learn more about how AD works.  MS recommends a minimum of 2 DCs in a forest for AD failover.
