How long can a domain be shut down

    Question

  • Hello All

    I need to shutdown all of the domain controllers in a domain for an extended period of time and I'm wondering if there is anything to worry about. 

    I am aware about the tombstone issue when you shutdown one domain controller, I just want a sanity check about what to expect if all the domain controllers are shut down.

    Thanks

    P.S. The only purpose for this domain is Exchange, no client PCs or servers.  The Exchange server will also be shutdown.

  • Do you if setting it to 0 will make it infinite? >>> I don't think so,please don't set 0 :-))You should modify long time interval..(so just plan that.)

    also check the article to modify Tombstone Lifetime for a Domain;

    And you should take a full backup of PDC before the process.

  • Well, you won't have access to domain services for one. :)

    A few things that come to mind:

    • Don't let them sit offline for 180 days.
    • If your DCs host DHCP, all leased addresses will expire (consider this for items like printers or access points that don't normally shut off).
    • Do you scavenge DNS? If so, keep in mind that records will need to be created again.

  • Hi

    what to expect if all the domain controllers are shut down.>>> If all DC's be turn off and will not be replication request,change AD objects,etc..Just you should be careful about tombstone lifetime period.this is normally  60 days or 180 days, depending on your verson of Windows.

    But as you know there is possible effects on clients when PDC is unavaible,check the artciles for effects;

  • Joseph_Moody:  The domain in question is only in place for Exchange, and all users have been moved off that server, but we want to hold on to the Exchange environment for a while for litigation purposes.

    Burak:  Thanks, I think I'm going to go with changing the tombstone period.  Do you if setting it to 0 will make it infinite?

    Thank you both for the feedback.
