Server freezes while generating Exchange GRT Catalog (Exchange Granular Restore Catalog). This happens when the backup destination is on a network share.


  1. Disable Exchange GRT Catalog generation, so that it does not freeze the server when it attempts to generate the Exchange GRT Catalog again. Exchange GRT Catalog Generation can be done even at a later point of time.

    How to enable or disable Exchange GRT Catalog Generation?

    ARCserve D2D r16.5
    ARCserve D2D r16.0 \ Update 7
  2. Make sure ARCserve D2D is at r16.0 Update 7 or later, or at 16.5.
  3. This problem was seen when ESET Mail Security Software was installed. Please refer the following article if ESET Mail Security Software is installed on the computer, otherwise proceed to Step 3.
  4. Apply the following MS Hotfixes,

    2029048 - Applications that use the TDI driver for network traffic may stop responding in Windows Server 2008 or in Windows Vista

    2665809 - You cannot exclude ports by using the ReservedPorts registry key in Windows Server 2008 or in Windows Server 2008 R2

  5. This step suggests to disable NetBIOS over TCP/IP option, As per Microsoft, NetBIOS over TCP/IP (NBT, or sometimes NetBT) is a networking protocol that allows legacy computer applications relying on the NetBIOS API to be used on modern TCP/IP networks. It exists on Windows OS only for backward compatibility. Unless you have an application that requires NetBT this should not be enabled. Windows Internet Name Service (WINS) is Microsoft's implementation of NetBIOS Name Service (NBNS).

    Note: - If there are legacy computer applications relying on NetBIOS over TCP and if NetBIOS over TCP is disabled, then those applications might not work properly. Please verify if this is required in your environment before disabling this.

    Note:- If NetBIOS Over TCP/IP is required in your environment and if it cannot be disabled, then we would suggest you to use a local removable drive as the backup destination. This server freeze problem is not seen when ARCserve D2D is configured to use a local volume as the backup destination.

    Steps to disable the NetBIOS over TCP/IP:-

            a. Select Disable NetBIOS Over TCP from the TCP Properties. Also remove any IP if it is present in WINS Server Properties.


            b. Stop and disable the NETBT Driver from the Windows Device Manager under Non-Plug and Play Drivers.
                This disables the SMB direct host listener on TCP/445 and UDP 445.
                Try the following steps:

  • Open Windows Device Manager.
  • Click the View menu, and click Show hidden devices.
  • Expand Non-Plug and Play Drivers, right-click NETBT driver, and then click Properties
  • Goto the Drivers tab. In the startup type drop down, select 'Disabled', and then click ok.


              c. For the DHCP clients, disable NetBIOS from the DHCP Scope options. Refer the following Microsoft Knowledge Base Article,
        , please refer to “Disable NetBIOS on the DHCP server”.

                  If you see '044 WINS/NBNS Servers' under DHCP Scope Options, please uncheck that as well. 

  1. Reboot the server.
  2. If the Backup Destination is a NAS Device, make sure the firmware is updated. If it is a Windows OS, make sure it is at the latest Service Pack.
  3. Before generate catalog make sure that there are no backup or merge related problems.

    If you find a backup or merge related problems fix it first and then attempt the Exchange GRT Catalog, or run a Full Backup and Generate Exchange GRT Catalog from the Full Backup.

  1. Suggest to generate Exchange Granular Restore catalog manually,
  2. If the Exchange Granular Restore catalog generation was succesfull in Step 8, then you can enable it as part of the regular backup. Please refer the link to Advanced Settings in Step 1 to enable Exchange GRT Catalog Generation.
