Microsoft has an error lookup tool [0]:

    $ err 2450
    # for decimal 2450 / hex 0x992
      NERR_BadUasConfig                                     lmerr.h
    # /* The user accounts database is not configured correctly.
    # */
    # No results found for hex 0x2450 / decimal 9296
    # 1 matches found for "2450"

> Microsoft has an error lookup tool

My little one liner has the advantage of having worked for me since Windows 98 days (OK, Perl did not have `say` then), but this tool provides more clues:

    C:\> Err_6.4.5.exe 343
    # for decimal 343 / hex 0x157
      KERNEL_THREAD_PRIORITY_FLOOR_VIOLATION                         bugcodes.h
      ERROR_EXTERNAL_BACKING_PROVIDER_UNKNOWN                        winerror.h
    # The external backing provider is not recognized.
    # for hex 0x343 / decimal 835
      ERROR_INVALID_SERVER_CERT                                      raserror.h
    # as an HRESULT: Severity: SUCCESS (0), FACILITY_NULL (0x0), Code 0x157
    # for decimal 343 / hex 0x157
      ERROR_EXTERNAL_BACKING_PROVIDER_UNKNOWN                        winerror.h
    # The external backing provider is not recognized.
    # 4 matches found for "343"

    C:\> wm 343
    The external backing provider is not recognized.
