x64 Windows and Exchange 2007- No VSS Writers RRS feed

  • Question

  • I am trying to use BES 11d to take VSS backups of E2K7, which fail for all E2K7 servers.


    When I check the vss writers on each exchange 2007 box I get the below, on exchange 2003 servers, backups work fine and there are plenty of writers listed, anybody else come across this??


    Microsoft Windows [Version 5.2.3790]
    (C) Copyright 1985-2003 Microsoft Corp.

    C:\Documents and Settings\exchm>vssadmin list writers
    vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool

  • I had the same error on some Exchange servers I had worked on recently. In the end we worked out that it was due to using the NewSid utility on a VMWare environment to build servers fast. Try the following steps:


                1. Stop the Microsoft Shadow Copy Provider & Volume Shadow Copy Service


    2. Export the contents of the HKLM\Software\Microsoft\EventSystem key to a .reg file (as a backup).

    3. Delete the HKLM\Software\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\Subscriptions key. (Just delete the Subscriptions subkey; leave the EventClasses key.)

    4. Restart the server.

    5. Run the "VSSADMIN LIST WRITERS" command.

    This causes the VSS entries in the HKLM\Software\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\Subscriptions key to be rebuilt when the writers initialize.


    If that does not resolve it try this:


    Check the Registry - HKEY_CLASSES_ROOT\CLSID\{FAF53CC4-BD73-4E36-83F1-2B23F46E513E}\InProcServer32
    - check right pane for (Default)
    - ensure this is pointing to the correct location
    à %systemroot%\system32\ES.DLL


    Try launching each of these consoles:


    - perfmon /wmi
    - msinfo32
    - wmimgmt.msc


    If the above works out without any issues, please run these commands on the server:


    Net stop vss

    Net stop swprv

    regsvr32.exe /i %windir%\system32\eventcls.dll

    regsvr32.exe /i %windir%\system32\swprv.dll

    regsvr32.exe %windir%\system32\vssui.dll

    regsvr32.exe %windir%\system32\vss_ps.dll

    regsvr32.exe %windir%\system32\msxml.dll

    regsvr32.exe %windir%\system32\msxml2.dll

    regsvr32.exe %windir%\system32\msxml3.dll

    regsvr32.exe %windir%\system32\msxml4.dll

    regsvr32.exe %windir%\system32\ole32.dll

    regsvr32.exe %windir%\system32\oleaut32.dll

    regsvr32.exe %windir%\system32\es.dll

    regsvr32.exe %windir%\system32\comsvcs.dll

    vssvc /register

    net start swprv

    net start vss

    Brilliant, thanks Rhys, that worked a treat! Yes, the servers were provisioned for esx also..

    Excellent solution. Worked like a charm. We have been strugeling with this issue for ages.

    Anyone know if newsid has any other issues we should consider when using it ?

    Too bad microsoft does not have a general tool (for all types of OS)... like newsid. Sysprep is different for every OS and even service pack

  • Exellent!!!!!!!!!! Thanks a LOT!!!!!

    I had this trouble on the real servers, which were cloned using NewSID. It was my mistake =(

  • This did *not* work for me.  Now nothing displays when I type 'vssadmin list writers.'

    I had to use regsvr32 from %SYSTEMROOT%\system32 since I have a 64 bit system.  This restored all my writers -- all but 'Exchange Writer' which I'm having a problem with.

  • Thanks to Ryhs Winter too.
    I had the same problem with Windows 2003-SP2 64-bit and Exchange SP1.
    I hate NewSID.
