Sysvol FRS to DFSr migration

    I successfully went through the frs to dfsr migration for my sysvol using the
    dfsmig utility. (succesfully went through "dfsrmig /setglobalstate 3")

    However, Backup exec fails when trying to back up the system state. It
    states "sysvol share" is corrupt. This did not occur until I migrated.

    Are there some cleanup steps I can go through after the migration is complete?
    Can I set FRS to disabled?

    Thanks,
    Bob

    BE is DFS Aware, but when it backs up sysvol it s marked as part of the
    "system state".

    Is FRS nevcessary for anything other than sysvol? I would like to see what
    happens if I try to backup without frs running

    Thanks,
    Bob

  6. Hello,

    As you have migrated the SYSVOL folder to DFRS, the FRS can be safely
    disabled if no any other replication groups are using FRS.

    From my search, it seems that there is a compatibility issue between
    Symantec Backup Exec and DFSR. In the following Symantec knowledge base
    article, it provides a workaround by stopping the DFSR service. As this
    issue is related to Backup Exec, I suggest that you contact Symantec
    support to see whether Backup Exec is compatible with DFSR and whether
    there are any updates. Meanwhile, I suggest that you use Windows Backup to
    backup System State to see whether it works. If so, the SYSVOL migration
    should have been completed successfully and the problem lies in Backup Exec.

    Does Backup Exec for Windows Servers (BEWS) version 10d and above support
    Microsoft Windows Server 2003 R2?
    http://seer.entsupport.symantec.com/docs/281856.htm


    If Windows Backup also encounters problems, please try to perform the
    following steps to verify 'Eliminated' state works fine.

    Step 1: Verify the DFS Replication global migration state is set to
    eliminated by running the following command:

    DfsrMig /GetGlobalState

    Expected Output: The current DFSR global state: Eliminated. Succeeded.

    Step 2: Verify that SYSVOL and NETLOGON shares are pointing to paths under
    SYSVOL_DFSR Share
    ---------------------------------------
    1. Click Start -> Run, type "regedit" in the text box, and click OK.
    2. Locate the following registry value to ensure that it is pointing to the
    right path. By default, it should point to "C:\Windows\SYSVOL_DFSR\sysvol"

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters\Sy
    sVol]

    Step 3: Verify that there are no more NTFRS objects
    -----------------------------------
    NOTE: The ADSI Edit tool is included in Windows 2003 Support tool. If you
    cannot find this tool, please install first Windows Server 2003 Support
    tool.

    1. Click Start -> Run, type "adsiedit.msc" in the text box, and click OK.
    2. Locate the CN=Domain System Volume (SYSVOL share), CN=File Replication
    Service, CN=System, DC=<Domain>, DC=<local> item, and ensure no child items.

    Note that it may be necessary to force Active Directory replication and a
    DFS Replication Active Directory poll on each domain controller to pick up
    changes from Active Directory, if it is desired not to wait for this to
    happen automatically. To force Active Directory replication, use RepAdmin
    tool. To force DFS Replication Active Directory poll, use DfsrDiag PollAd
    command.


    Is the SYSVOL path correctly? Is the NTFRS object removed properly? If the
    Windows Server Backup Tool fails to backup the system state because of the
    SYSVOL corruption, could you please help to collect the Directory service
    MPS report for our further investigation?

    Thank you for your response.

    On one of my DCs (2008 in native mode) I have peformed the following:

    1. C:\Windows\system32>dfsrmig /getglobalstate Yields
    Current DFSR global state: 'Eliminated'
    Succeeded.

    2. Regedit shows that
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters\SysVol] is set to "C:\Windows\sysvol\sysvol".

    3. It does not appear there ar eany child items by using the adsiedit
    program.

    Another note on my other DC the sysvol key states C:\Windows\SYSVOL_DFSR\sysvol

  9. Hello,

    As I mentioned in my last post, could you please have a try to backup the
    system state by the Windows Server Backup Tool?

    To the further troubleshooting, please answer the following questions:

    1. In the Explorer, can you find the SYSVOL folder under the C:\Windows\?

    2. In the Windows Server 2008 event log, is there any logs recorded that
    may indicating the DFSR error?

    For your reference:

    To give a more clear understand of the domain environment, could you please
    send me the Directory Service MPS report to me?
