How to recover Exchange accounts when domain controller is no longer active... RRS feed

  • Question

  •  

    We had a working Exchange server together with Active Directory (installed on another machine- domain controller)

     

    Exchange accounts were actually domain accounts. Then the domain controller machine's hard disk failed and there was no secondary domain controller (although we could manage accounts through exchange machine- with active directory users and computers mmc tool on the exchange server machine).

     

    After all we re-installed win2003 server and active directory (with the same domain name as before) on the domain controller machine.. i am aware that the domain is not same but is there a way of importing those old accounts and profiles to this new domain (from the exchange machine)

     

    when i run exchange system manager it tells:

    There is no Microsoft Exchange Organization in that domain.

    ID no: c1030a8c

    Exchange System Manager

     

    Thanks in advance.. I need urgent help....

  • Probably the quickest way to get the data back (exported out of the old database) is to purchase something like Quest's Exchange Recovery Manager for Exchange or OnTrack's PowerControls for Exchange.  These tools will let you mount a database WITHOUT an Exchange server and merge data out to a PST or in to another mailbox. 

     

    If you are looking to do this manually, take a look at this whitepaper.

    What you want to build is a recovery server.

    Dear customer:

     

    In order to better troubleshoot the issue, please provide me with the following information.

     

    1.     Did you have a backup for the previous DC?

    2.     Did you have a backup of Exchange server 2003 mailbox store?

     

    If you have a backup for the old DC, you can restore your data from the backup, for detailed information about how to recover a Windows Server 2003 operating system domain controller, please refer to the following documents:

    Active Directory Operations Guide Version 1.5

    http://www.microsoft.com/downloads/details.aspx?FamilyID=4a82eccc-76d6-4431-aac4-1ef1ba11dbea&displaylang=en

     

    If you don’t have a valid backup for the old DC, since the previous DC is unavailable, your Exchange server might stop functioning. If you have a backup of Exchange server 2003 mailbox store, you can try the following methods to restore your mailbox database:

     

    1.     Make a note of the following information that is on the previous Exchange Server 2003 computer:

    • Organization name

    Administrative group name

    Storage group name

    2.     Create a new domain with the same name as the old one that Exchange server belongs to.

    3.     Run Exchange Server 2003 Setup, and then create a new organization that uses the same name as your existing Exchange organization.

    4.     Do one of the following, as appropriate to your situation:

    • If the name of your administrative group is First Administrative Group, go to step 6.

    -or-

    To install Exchange Server 2003 to an administrative group other than the First Administrative Group:

    a. Run Exchange Server 2003 Setup, and then install Microsoft Exchange System Management Tools.

    Important At this point, do not install Microsoft Exchange Messaging and Collaboration Services. Type the name of your administrative group (the same name as the administrative group on your production server). 

    b. Start Exchange System Manager.

    c. Right click your organization, and then click Properties.

    d. Click the General tab, click to select the Display administrative groups check box, and then click OK.

    e. Quit and then restart Exchange System Manager.

    f. Right click Administrative Groups, point to New, and then click Administrative Group.

    g. In the Name box, type the name of the administrative group, and then click OK.

    Important: You must use the same name that you used to name the administrative group on your production Exchange Server 2003 computer.

    h. Quit Exchange System Manager.

      

    5.     Run Exchange Server 2003 Setup, and then install Microsoft Exchange Messaging and Collaboration Service and Microsoft Exchange System Management Tools (if the Exchange System Management Tools are not already installed on the server).

    6.     Configure the storage group name to use the same name as the production Exchange Server 2003 computer. To do so:

     

    a. Start Exchange System Manager.

    b. Expand Administrative Groups, and then expand AdministrativeGroupName.

    c. Expand Servers, and then expand YourServerName.

     

    If the name of the storage group on the production server uses a name other than First Storage Group, configure the storage group name to use the same name as the storage group on the production Exchange Server 2003 computer. 

     

    7.     Dismount the database. To do so: a.  Right-click Mailbox Store, and then click Dismount Store.

    b. Click Yes when you are prompted to continue.

    c. Right click Mailbox Store, and then click Properties.

    d. Click the Database tab, and then click to select the This database can be overwritten by a restore check box.

    e. Click OK.

    f. Quit Exchange System Manager.

     

    8.     Delete the existing database and log files that are on the recovery server. To do so:

    a. Start Windows Explorer.

    b. Locate and then click the C:\Program Files\Exchsrvr\Mdbdata folder.

     

    Note: The C:\Program Files\Exchsrvr folder is the default installation location for Exchange Server 2003. If you installed Exchange Server 2003 to a different folder, the location of the Exchsrvr folder is different on your computer.

     

    c. On the Edit menu, click Select All.

    d. Press the DELETE key.

    e. Click Yes when you are prompted to confirm the deletion.

     

    9.     Restore the database files from backup.

    10.            Mount the database. To do so:

     

    a. Start Exchange System Manager.

    b. Expand Administrative Groups, and then expand AdministrativeGroupName.

    c. Expand Servers, expand YourServerName, and then expand YourStorageGroupName.

    d. Right click Mailbox Store, and then click Mount Store.

    e. Click OK when you receive the message that indicates that the store successfully mounted.

     

    11.            Create a new test user in Active Directory Users and Computers. Make sure that you do not make the new user account mailbox-enabled. To create the new user:

    a. Start Active Directory Users and Computers.

    b. Right click Users, point to New, and then click User.

    c. Specify the user name and the user logon name in the appropriate boxes, and then click Next.

    d. Specify the password information for the user, and then click Next.

    e. Click to clear the Create an Exchange mailbox check box, and then click Next.

    f. Click Finish.

     

    12.            In Exchange System Manager, expand Mailbox Store, right-click Mailboxes, and then click Run Cleanup Agent. 

    13.            Recover the mailbox. To do so:

    a. Right click the mailbox that you want to recover, and then click Reconnect.

    b. In the list of Active Directory accounts, click the user account that you created in step 12, and then click OK.

    14.            Check whether you can use Outlook connects to the test user’s mailbox.

     

    Please let me know the result. If anything is unclear, please feel free to let me know.
