Hi,
We are running Active Directory and DNS Server on the Same Windows Server 2008 R2 as Virtual Machine on vSphere 5 Platform. Since it is for College environment every month we have to delete or create 1000 users. Recently iSCSI based Storage which is used to store the Virtual Machines (Includes Active Directory VM also) is corrupted. Then we have restored the Active Directory Server from the Clone image (of Active Directory) which was taken in Dec 2012. But now all the client machines are unable to authenticate through Active Directory. If we rejoin the client machines to Active Directory, then the authentication successful. But in this way we have to rejoin the 5000 Client machines which will take more than 10 days to complete.

1) Is there any alternative solutions to make Client machines authenticated through Active Directory without rejoining to domain?
2) Why there is a change in a client machines behavior even after restoring the Clone of the existing Active Directory VM?

Should always keep the backups at least moderatly current on the servers for the most part.  If the server is to out of date (old backup) it breaks the trust relationship between the devices, kind of like its adding a system already present ahead of its time.  Rare cases make sure the date is correct on the AD server and reboot.  There are a couple options of restoring the trust relationship between the clients but that also involves connecting to each of the 5000 clients.
