Put Computer back into AD RRS feed

  • Question

  • Big mistake:

    Big mistake: in active directory management center, domain computers, I deleted the wrong server (the one that has exchange).

    The trash is not activated. Can I put it back in place?

  • Might try rejoining domain.

  • I don't like the "try". I would have to connect as local administrator, leave domain and re-join domain, so create a new computer account.

    What will happen with all what was installed as domain admin on the deleted computer (exchange)? Will it be lost?

    Isn't it better (safer) to restore a backup from VM with active directory?

    Hard to say, but then you asked in hyper-v forums. Better to reach out to exchange experts in dedicated forums over here.

  • If you have backups of the Domain Controller, you could extract the NTDS.dit database from the backup, and use some like the Veeam Explorer for Active Directory to restore the AD object

  • If you are going to perform an authoritative restore on the domain, you should do it quickly to minimise record drift (and make use of the weekend as an opportunity to drop a domain controller I would suggest). If the Exchange Server has updated its computer account password between the backup being made and the time that the object was deleted, you will have to re-join the Exchange server to the domain anyway!

  • Hi,

    BTW, If you have Windows Server 2012 R2 or later, and If the Active Directory Recycle Bin is enabled, you can restore the deleted objects, more details:

  • Hi ,

    Thanks for your posting here.

    Since your query is more related with AD and exchange , which our forum doesn't focus on , I would suggest you have this asked in AD forum and exchange forum for better answers.

    Here is the link:

    https://social.technet.microsoft.com/Forums/en-US/home?forum=winserverDS

    https://social.technet.microsoft.com/Forums/office/en-us/home?category=exchangeserver

    The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

    Best Regards,

    Candy
