Scan Error 301 - SystemRoot Share Access Required to Scan

Version 3

    Symptoms

     

    When performing a scan, you receive the message:

    Error 301

    SystemRoot share access required to scan

     

    Cause

     

    Protect is unable to connect to the remote machine’s system share. This may occur if the administrator has unshared the systemroot (typically C$ or similar) or has disabled the AutoShareServer(Wks) via the registry.

     

    Resolution

     

    1) Test connecting remotely to the admin shares to see if any additional error is given.

    Examples:

     

    From Windows explorer:

    \\machine\C$

    \\machine\ADMIN$

     

    Or from command-line:

    net use \\machine\IPC$ (optional specify user/pw)

    See: Net use

     

    Test opening a file to test read access.

    Test creating a .txt file or editing a file to test write access.

     

    If you are unable to connect to the admin shares or successfully perform the above tests you most likely need to review the Scanning Prerequisites.

     

    2) You may need to restore administrative shares with the following steps:

    • Set Value from 0 to 1 in these registries:
      • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters\AutoShareServer
      • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters\AutoShareWks

    Additional Information

     

    If you receive the following error when testing access to admin shares:

    “System Error 1130 not enough server storage”


    We have previously seen this resolved by following steps in this third party documentation:

    Note: Following this documentation is at your own risk. Setting the IRPStackSize value larger than it needed can waste system resources and possibly cause other failures.
