    Problem

    When running a Software Distribution task the task fails with the error "Failed to download all additional files".

     

    Here we provide a few suggestions on how to resolve this issue.

     

    Troubleshooting


    Reset the package hash

    A common issue when getting the error “FAILED TO DOWNLOAD ALL ADDITIONAL FILES—TASK MANIFEST” is that the hash on the file has been modified. Try resetting the hash on the package.

    Gather client logs that can assist in Troubleshooting

    • C:\Program Files\LANDesk\LDClient\data\sdclient_task#.log
    • C:\Program Files\LANDesk\LDClient\sdclient.log
    • C:\Program Files\LANDesk\LDClient \ tmcsvc.log
    • C:\Program Files\LANDesk\Shared Files\proxyhost.log
    • C:\Program Files\LANDesk\LDClient\ SDClientTask.[Core-Name].[task#].log

     

    Verify that the files can be downloaded

     

    Refer to the above logs to determine which file is having a difficult time downloading.

    From the agent workstation, try to download the Task Manifest file as local system manually as directed below:

     

    In this example replace “core” with the name of your Core Server. The #### below will need to be replaced with the Task ID.   (To gather the task ID right-click the scheduled task and select "Info".  The ID # will be in the top right)

     

    “C:\Program Files\LANDesk\LDClient\sdclient.exe” /f /p="Http://core/ldlogon/filelists/taskmanifest####.inI"


    If successful the task manifest file will be downloaded to ..\Program Files\LANDesk\LDClient\sdmcache\

     

    Where Core Server Name is

     

    "C:\Program Files\LANDesk\LDClient\sdclient.exe" /f /p="Http://LDMS2016:9592/ldlogon/filelists/taskmanifest.LDMS2016.8.3.ini"

     

    In this example there is no need to replace “localhost”, but you do need to replace the #### with your Task ID. When you use localhost Windows resolves that to the client computer's address that the command is initiated from. The purpose of doing this is to use sdclient to redirect the request properly. If this is successful then proxyhost and lddwnld are most likely working properly.

     

    C:\Program Files\LANDesk\LDClient\sdclient.exe /f /p="Http://localhost:9592/ldogon/filelists/taskmanifest####.ini"

     

    Example

     

    "C:\Program Files\LANDesk\LDClient\sdclient.exe" /f /p="Http://localhost:9592/ldlogon/filelists/taskmanifest.LDMS88.8.3.ini"

     

     

    Get the sdclient_task##.log

     

    Enable XTrace
