  • W2K3 R2 AD GC with DFS Dead, how to rebuild?

    Hi all,

    I had two W2K3 R2 Standard Edition 64 bit ...

    The Main first server is FS01, it is a full five FSMO roles and it is a AD with DFS + DFS Replication some share folder and target to FS02 the second AD with DFS Server.....

    My big problems are one day the Main Server dead, so I need reinstall the Windows and the HDD are like the new one .... and I seize the FS02 second server to become the five FSMO role and make the GC from the dead FS01 server to FS02, mean that now the FS02 become the Main Server after seize and give it to be GC roles .... but the problem come here ....

    I seize the AD and clean up the meta by following step

    http://www.petri.com/seizing_fsmo_roles.htm
    and
    http://www.petri.com/delete_failed_dcs_from_ad.htm
    (Just clean up the metadata part, other step have not following)

    My user and workstation can using the FS02 for the DFS and working .....

    But I check the FS01 after reinstall Windows, and join the Domain and installed the DNS Server plus give it the File Server with REplication Role from the Management your server ...

    I open the DFS Management Interface on the FS01 Server, Oh, it is nothing here, lose all the inform that the record, it is like total new DFS what not setting it up ...

    But on FS02, I open the DFS Management Interface same like the FS01 I do, I can see the Namespaces Root, and the Folder, and the Folder Target that etc record, BUT, have some error here with RED "X" on some tab. I am lost the way how to fix it, I want the reinstall FS01 Server can save back the files where on the FS02 (Before the FS01 dead, the DFS Replication on the Target and Group Memeber setting is FS01 ---> FS02 (Mesh)) Now I am wonder why it will not auto copy the FS02's files to FS01 ...

    Here are my DFS Setting
    My setting of the DFS is

    Domain:
    company.local

    Namespace:
    EGR

    DFS Folder:
    Design Department

    DFS Folder Target (Design Department):
    Point to
    \\FS01\Design Department FS01
    \\FS02\Design Department FS02

    DFS Replication Setted copy the data from FS01 to FS02

    Share will be show like that on working environment
    \\company.local\EGR (Root Namespace)
    Under it can see
    \\company.local\EGR\Design Department



    Here are the error (RED "X") of the FS02 DFS Management Interface I see.....

    On FS02, I check the Namespaces tab, where the RED "X" of the DESIGN DEPARTMENT (Replication) and see the error, it show me
    <Unknow> (Design Department)
    The member
    CN=bdxxxxxxxx, CN=Topology, CN=company.local\\egr\\design
    department, CN=DFSR-GlobalSettings, CN=System, DC=company,DC=local does not refer to a valid computer object


    On FS02, I check the Replication tab, where the RED "X" of the MEMBERSHIP and see the error, it show me
    <Unknow> (Design Department)
    The member
    CN=bdxxxxxxxx, CN=Topology, CN=company.local\\egr\\design
    department, CN=DFSR-GlobalSettings, CN=System, DC=company,DC=local does not refer to a valid computer object


    On FS02, I check the Replication tab, where the RED "X" of the CONNECTIONs here have two RED "X", include the FS02 too ....

    On the first "X", it show ..
    <Unknown> to FS02
    The sending member object
    CN=bd9XXXXXXXXX, CN=Topology, CN=company.local\\egr\\design
    department, CN=DFSR-GlobalSetting, CN=System,DC=comapny,DC=local in Active Directory is invalid.

    On the second "X", it show
    FS02 to <Unknown> to FS02
    The sending member object
    CN=bd9XXXXXXXXX, CN=Topology, CN=company.local\\egr\\design
    department, CN=DFSR-GlobalSetting, CN=System,DC=comapny,DC=local in Active Directory is invalid.


    Hope here someone can help me.

    Actually, on my case, if it happened on your server, what the step by step you will do to make the two Server can sync again and the DFS Replication work again?

    Thank you of your time

    Did you rebuild FS01 with the same name?

        Re: W2K3 R2 AD GC with DFS Dead, how to rebuild?

        And I have not rebuild any directory on the FS01 on this D: driver

        Before the format HDD, it have the DFSRoots and a Folder Target called "Design Department FS01"

        I try manual rebuild and setting the permission to above folder ...

        The DFS Replication still not working ....

        So I don't know what is wrong here.

        Do my rebuild step have something miss or wrong?

        Thank you of your time.

            Here are the Event Viewer Log of

            File Replication Service

            Warning: 13508
            The File Replication Service is having trouble enabling replication from FS01 to FS02 for c:\windows\sysvol\domain using the DNS name fs01.egr.local. FRS will keep retrying.
            Following are some of the reasons you would see this warning.

            [1] FRS can not correctly resolve the DNS name fs01.egr.local from this computer.
            [2] FRS is not running on fs01.egr.local.
            [3] The topology information in the Active Directory for this replica has not yet replicated to all the Domain Controllers.

            This event log message will appear once per connection, After the problem is fixed you will see another event log message indicating that the connection has been established.

            Information ID: 13516

            The File Replication Service is no longer preventing the computer FS02 from becoming a domain controller. The system volume has been successfully initialized and the Netlogon service has been notified that the system volume is now ready to be shared as SYSVOL.

            Type "net share" to check for the SYSVOL share.

              Im pretty sure you can't rebuild a faulty DC with the same name afer seizing.
              Please reinstall with a different name.

              But didn't you have backups?
